Video summary
The video documents a technician's troubleshooting process on a Dectron pool unit that was suffering from dangerously high indoor temperatures and excessive head pressure. The system is designed to provide both air conditioning and dehumidification for pool areas, utilizing a complex network of coils, valves, and a boiler for backup heating. Initially, the facility reported that the room was becoming unbearably hot despite claims that the boiler was turned off; however, the technician discovered that a specific three-way valve had been left in an incorrect position, effectively bypassing the cooling circuit and allowing hot gas to circulate unnecessarily. This misconfiguration caused the system to trip on high head pressure alarms almost immediately upon attempting to run the dehumidification cycle, confirming that the root cause was not the boiler but rather a failure in the refrigerant flow management within the reheat section.
Upon disassembling the unit to inspect the internal components, the technician identified two distinct issues contributing to the malfunction. First, the faulty valve mentioned earlier was corrected by closing the bypass path, which immediately stabilized the discharge pressure and allowed the system to cool effectively without tripping safety limits. Second, a critical airflow restriction was found in the form of severely worn pulleys on the blower motor assembly. These degraded pulleys were destroying new belts and significantly reducing air volume, which exacerbated the head pressure problems when the system attempted to run the reheat coils. The technician replaced the damaged pulleys with high-quality aftermarket parts, restoring proper airflow and demonstrating a dramatic reduction in noise levels and vibration compared to the unit's previous squealing state.
After reassembling the equipment with the new pulleys and correcting the valve positions, the technician tested the system under various operating modes to ensure stability. The unit successfully maintained target humidity levels around 50% while keeping supply air temperatures within safe ranges, proving that the combination of the fixed valve and restored airflow resolved the overheating crisis. Although some minor issues remained, such as a malfunctioning keypad display and a sensor that required manual adjustment, the core mechanical problems were addressed. The technician concluded that the primary failure was a result of poor maintenance history and incorrect valve settings left by previous workers, emphasizing that even small oversights like an open bypass valve can lead to catastrophic system failures in complex industrial dehumidification units.

We go.
Okay. Sometimes this works, sometimes it
don't. That works real great. Oh, great.
Now they don't even want to work. That's
great. Freaking garbage, man. I hate
dealing with this.
>> This video is brought to you in part by
True Tech Tools. Quality tools.
Essential support.
All right, guys. So, it's bright and
sunny out here, but let's go inside.
We're going to take a look at this
Deckron unit. I've worked on this thing
before actually. Uh I think I made a
video on it earlier this year or you
know technically the end of last year
and replaced some three-way valves uh
stuff like that and it's basically
making the water way too hot and they
say it's not the boiler doing it. Uh
Detectron unit basically
dehumidification for pool areas. So
you've got air conditioning and
dehumidification. So you got reheat
meaning they use the condenser uh water
instead of running it into a water
tower. They run it into the air path and
if they don't need that then it goes
into the water tower. also has a boiler
as backup which allows it to keep the
air temperature warm enough so that
you're above the pool temperature by a
degree or two. I just got here and took
a quick look at it and trying to figure
and track things down cuz I mean I don't
have this thing memorized. It's a little
different than the one I have at one of
my other locations. So, let's go in here
and take a look at it.
All right, so we've got one compressor
here. My other unit I work on has like
four total. So, this compressor I was
following the pipes here to try to
figure out what's going on. So, we've
got the discharge gas here. You can kind
of see that green laser there, maybe.
Comes across
and comes up to these two valves. These
valves are what I changed here and here.
And then you got a bypass, so to speak,
that goes around them. It can go through
this valve right here and down into that
coax coil there. And then this one here
comes in and goes to this coax coil.
Coax coil just water and refrigerant
loop. So comes into that, comes out of
it here,
comes around, goes down through a check
valve,
and who knows what it's doing. So it's a
little confusing. I'm wondering, are
these valves acting up or what's going
on? So when this is usually running, you
got this blower here just cranking some
major CFM across it, going to the duck
work that then goes on out. So it makes
a lot of noise. So, here's the boiler
coil, and
you've got the reheat coils right over
here. These are the condensers when
they're doing dehumidification.
Otherwise, these are bypassed. Here's
your evaporator one. Evaporator number
two. And like I said, I've replaced all
the core dryers. I just checked that
valve over there. They just turned the
water towers back on. So, they don't
understand why it's getting so hot now.
They turn it on. So it uh can bring
outside air in here through this one
here which goes onto the outside,
comes across
into here. This is closed. The other
location I work at, half the controls on
it don't work. This one here, I don't
know, kind of partially. I just kind of
recently started doing this. One of the
other guys uh retired and so it's my
baby now. Being it's getting uh hot in
there makes me Okay. is does it do it
when the system is just calling for
cooling? Because in reality, if it's not
the reheat causing it, cuz they claim
that they turned off Yeah, that's open.
That's good. They claim they turned off
the boiler and it was still getting
warm, which means the reheat would be
doing all of the work there, causing it
to get warm. You would think that's
assuming that the valve isn't screwed
up. So, you got all kinds of little
hidden things like that right there.
little screens or check valves comes
into that and then would come out like
here you got liquid coming in. So after
it condenses it in that coil there
either going to the roof to the water
tower or coming over through
this coil here. It then turns into
liquid. The liquid then there it is. It
goes back in there of course underneath
there. You can't even see any of that.
Goes into there and then comes back. So
I got to see what that that valve does.
Comes through the filter dryer, then
into the evaporators. The evaporators
are pretty much always getting some some
love from the liquid refrigerant. Goes
through, comes back, the two combined
together here,
and on back it goes to the compressor.
So the basic refrigeration system is
pretty simple. You know, when you don't
throw all this extra crap in there,
that's when everything goes to crap. So
like I said, it comes into an
accumulator and uh you got valve there.
It's open into this. It's probably not a
filter dryer. It's probably just a
screen. Then it comes back into the
compressor. What we need to find out now
is we're going to have to turn it on.
We're going to have to see what gets
hot, what don't get hot. My biggest
thing I wanted to know was what's going
on here. There's those two pipes that
were coming back. So, if it goes into
the reheat valve or into the reheat coil
here, it's going to come back on these
two here.
One's going to come through, come up to
here, and there's a uh looks like an
AXV, but it's some sort of motorized
valve. Then comes up,
comes through this thing, then goes into
this receiver and comes into the
receiver on the low half. The other one
comes up and comes on. Okay, so up here
is the end. Comes in on the end here. I
got to make sure all these are open. So
if it goes into these reheat coils,
which are condensers, goes into the
receiver and goes on out. Kind of the
same thing with the other stuff. If it
goes into the coax coils on one, it's
going to come out through a check valve.
The other one's probably going to come
out of it, too. Yep. As a check valve,
and then comes out and then goes up to
this little goofy device, which is
basically another valve that's going to
send it one way or the other. So it's
either going to run this one over to
that flat plate heat exchanger. That's a
coaxial and that's flat plate. comes
across, goes to this thing. And that
one,
look at that. It comes into that top
here.
Yeah. And that's the inlet. So, what the
crap? So, that's the return path. That's
the outlet. The outlet. So, yeah.
Anyhow, that kind of gives you an idea
of what's going on. I'm going to need to
study for a moment here what we got
going on. But that's a bit a gist of how
everything is. So, there's something
weird going on here. here. Maybe there's
a valve open that shouldn't be open. And
we'll figure this out. I think I might
have found one of the problems. So, this
comes back from
the condenser or the uh reheat coil and
comes up and goes to that valve there.
But if you look here, that valve is open
and that would bypass it, which then
would allow it to bypass and obviously
heat when you don't want it to. So, that
valve needs to be closed. And you know,
when you are doing a repair that
somebody else found, but since they're
not here no more, you just kind of do
what you're told and don't try to go
more than that. And this is the kind of
crap that happens. One of the many
reasons why it's always
counterproductive
to do a job someone else starts. But in
this case here, we had no options. So
that one should be closed. And this here
for giggles, let's make sure this one
here is actually open, which about have
to be. Otherwise, it would have probably
tripped out on something.
Open this valve before startup. Well,
yeah, no kidding.
That one is open. Okay, good. All right.
Now, let's look at some of these other
ones, cuz these other ones are kind of
like bypass, too. So, this one here,
hotter than blue blazes.
And see that one says B and A. So I put
A, A, B, A right here, and A right there
because when we unhooked all these, so I
was doing my work, I didn't want to do
whatever. Now I don't know if these need
to be I don't see these would have to be
bypassed because the solenoid should
open and close this. So these should be
open
at this point. I'm just having to go
through and double check it.
Yeah, that one's open.
That one's open, too. We might have got
it, but just in case, I don't want to
get too big a hurry cuz I was very, very
careful with those valves when I did the
work on them. And that one there, this
is what's kind of confusing. So, you got
a check valve here coming [music] from
that direction. This one here probably
needs to be open. This should probably
be open. That's a check valve right
there. And it is open. Yeah. We're just
making certain that all these are right
cuz I mean if that's the case right now
basically I just had one mistake so far.
That's all it takes to screw you. So
this valve here I wasn't sure about the
stem. So I checked the stem. I don't
want to pull that stem out any further
cuz it's that stem's got like a lot of
threads on it and I'm worried that it
may just back all the way out and then
blow the whole charge. Well, we've got a
valve there that we can shut which would
kill that side. You've got discharge
coming over the compressor. I shut that
just in case. These are already closed
here. So, we're closed here. Closed
here. And technically, we're closed
here. So, I'm going to back that stem
out the rest of the way. It was also
leaking a little oil. So, that tells me
it's got a little bit of a leak there.
So, we got to tighten up. My worry was
if I back this out, it's going to blow.
It just don't seem like it just don't
seem right. And I tried looking it up
online. Yeah, I'm just a little I'm
thinking if I go any further. Okay,
boom. It stopped. Thank goodness. I I'll
tell you what, that's experience there.
You don't want to do something stupid
like that when you ain't 100% certain. I
mean, I looked up everything I could
find on it online.
And normally, a valve is closed and you
have to manually stem it open.
Those are questionable. Now, here's what
happened. This was quoted. I most likely
didn't have a lot of time. I don't know
what the whole whole story was. You can
see I've spent quite a bit of time right
now just trying to figure out what I
need to do on this thing. So, I'm going
to put a little bit of thread tape or
something on that thing as an extra
precaution. Um, I could not find
anything other than it was made in
Mexico.
Other than that, I didn't find no valve
body information on it at all. So, and
you know, I looked up that that right
there and it just didn't have much. That
body [music] there is starting to
completely fall apart though. So, let's
see if we can push that down.
Put that there. And there we go.
Good. It's on. Uh, so anyhow, the uh the
boiler that he said is off.
Can't be off cuz it's it's hotter and
crap in there. I mean, I feel tons tons
of heat coming in. I mean, I'm I'm
radiating radiating off that thing.
Yeah, that right there. You got a
three-way valve up here. And I kind of
figured that that was a possible problem
right off the bat. But the only reason
why it's doing it now is probably
because it's defaulting to that cuz I
killed power. It wasn't that hot
earlier. So now we've got that done.
We'll get that put back to normal. We'll
open these valves back up. For the most
part right now, it just seems like we
got one valve that was well other than
those there that were uh
one valve is in the wrong position
bypassing cuz normally you'd think all
your valves need to be out back open if
you're not like paying super close
attention. [music] But I think this was
a day and a half job that I was on this
cuz I mean I had to completely recover
everything out of it. The evacuation
didn't go real great. I think I had to
pull forever on it. I think I made a
video. I'm almost positive I did.
There we go. That would be really bad to
ride in that without any without any uh
It's so nice and dark in here. Got to
love it. Now the stems can go on. They
are brass, but they just don't give me
the warm fuzzy feeling. Um those have
looks like a rubber seal in there. It
does have a rubber seal in there. Does
that other one have a rubber seal? It's
got a rubber seal, too. Maybe it just
wasn't tight enough. I don't know. It
ain't going to hurt to put a little
thread tape around it. It's easy to
clean up. Okay, so it looks like the
threaded fitting wasn't on quite
straight. So, once I straighten it up a
little bit, they really didn't make
[music] this in a great position to get
too much of this, but hopefully that'll
keep it from leaking now. Man, I turned
that uh power back on and it went back
the other direction. The heat's not
radiating out as bad as what it was.
Okay, other than that, I mean, we got
everything pool water coming in. The
pool water came into here and here.
these two coils. You can see the water
going in
flow switch that's bypassing and they
didn't want to approve.
Uh yeah, we'll just not talk about that.
So water goes in, refrigerant goes in,
refrigerant should come out.
There we go. Okay. I had to watch some
of this and it's kind of be nice if I
made some labels, but this stuff's not
going to stick to this. It's all green,
nasty, chalky. Ate up from the chlorine.
But that discharge gas comes in, goes
through, potentially could bypass and
let that go in around that valve to let
a little something go through into the
pool uh while still sending most of it
down here to the main valve that's going
to send it whether it be to the main
condenser or the reheat coil. So that I
made a mistake on that one. So that one
goes that way or it can go this way. And
with judging from that valve there, it
looks like it probably can modulate one
or the other and do both possibly. Uh
which because otherwise it'd be just a
solenoid. So can't know everything. Uh
you might, but you know, whatever. So
I've corrected a couple arrows going in,
coming out. They all come in, whether it
goes through that reheat coil, which is
basically then your condenser. They all
combine together. They come through and
they come to that one valve there, which
is a metering device, probably a
holdback valve. That's if your uh
pressures and stuff are too low. It's
going to hold it back just like you
would on a rack. That valve has to be
shut and then it's going to come into
the receiver. Then you got liquid going
back out to the metering devices over
here for the evaporator. So in reality,
the only evaporators you got are over
here for cooling. The rest of it
condensers. Condenser whether it going
to water tower, condenser is going into
the pool to heat the pool, getting free
heat there. And if it needs
dehumidification, it's going to take
that hot gas and run it into the coil
that's behind here to reheat the air. So
that's how it basically is able to
maintain close to the same temperature
uh by neutralizing the cold air, which
then causes it to sweat. When it sweats,
it dehumidifies and there you go. So
yeah, it just took a second to kind of
follow it around. I think my only
problem is that valve right there. We're
going to put her together and kick it on
and see how it does. Blower on.
Well, that sounded good.
Humidity 75%. That's going to change as
the unit starts running. Yeah, I had to
go through here and mark things out.
There's your book.
Right here's something I see done wrong
all the time. Somebody just tease off
and decides to feed another evaporator.
They should be bullheaded into it. Bam.
That way it has to go equally one way or
the other. That's the right way. You can
also do it in series. Okay, I just
tested this out and labeled it because I
think this is going to be my baby. Open
definitely's down here. I uh flipped the
switch here on the side to see what it
would change to and sure enough I had a
lot of heat coming out. Closes up here.
These little quick reference checks just
make it easier. Sure, marker looks kind
of crappy at points, but I mean when you
can't read the freaking display, I mean,
give me a break. Supply air
is going up in temperature again. Great.
Now it's coming down. It must have that
or it shut off.
Yeah, it's 410A. So, 460 lb. Evaporator
is 86. It's dropping. So, something had
it must have kicked in. We either
weren't in a happy spot or something,
but something must have just kicked in.
Our evaporator wouldn't be dropping in
temperature otherwise
and we go into an alarm piece of you
know now I think about it that would
have been liquid refrigerant coming back
condensed refrigerant it would have
bypassed the holdback valve which would
have caused lower condensing
temperature. Now for all I know that one
right there may not work and maybe
that's why it was acting like that. So
what I need to know is if the reheat is
getting energized. So, I shut everything
down so I could get the doors off cuz
this is a pain in the butt.
My other one I've got has nice hinges on
it, and that's older than this one. So,
they must have cut cut cost and got rid
of the hinges. Or maybe it was an
option. I don't know. Either way,
they've changed their name so many
times, and it's just it's a Canadian
company, so half the time you get
somebody that speaks French and barely
can speak English, and then they all got
bought out. It's a pain in the ass.
Unfortunately, they own all of them. So,
let's go ahead and turn everything back
on.
They've got their own maintenance, guys,
for a lot of that crap. They don't even
sound faster than what it should be. See
if this thing kicks on here in a second.
If it does, we'll be able to tell
whether or not there's hot discharge gas
coming through the reheat coil, which in
reality it should be because we need to
run cooling plus the reheat to bring the
humidity down. One of the problems I had
with my other one was the reheat would
cause it to go off on high head
pressure, kind of like what it's doing
here. And um I had to bypass that. And
because they had no money, I had to
basically make it run the boiler with
the air conditioning, which is totally
inefficient. But when you don't have
$400,000 to replace one of these, that's
what you have to do. 350 400 What's
$50,000 anymore nowadays?
Wow, that thing is squeaking like a song
bird.
Not as bad when you got the door on. We
had a compressor, high pressure fault.
And I think the compressor just came on.
Let's go back here.
Should be able to feel Oh, yeah. That's
hot gas coming through there. That's
hot. Definitely. Okay,
that's hot liquid coming into the EXV
into the TXV. Starting to get cold
there. Starting to get cold there. Look
at that. We got flashing going on here,
which is great.
Uh, grant it just kicked on. Hopefully,
it goes solid.
Outlet,
it's subcooled.
Inlet, pretty warm.
Okay, so that means everything seems to
be going the right direction there.
That that liquid though is hotter than
crap. So, we're not getting anything
going into our main condenser, I bet
you. Cuz I mean, to be honest with you,
the the outlet the hot it's coming in
hot. Well, it was. It just went away.
Discharged 448. So, it sounds like we're
having our problem in our in our reheat.
So, the reheat might be our issue. That
would be that valve I replaced.
Hopefully, the right ones. Right now,
we're fine. Evaporated temperature is
55° even though we're bypassing a lot of
the air. 448 on head pressure. Yeah,
we're sweating there.
That's still got a lot of flashing.
Okay, let's see if we can close this up
a little bit more than what it was.
There we go. That way we got a little
something there. Forcing it through the
evaporator. If you look at the way they
do this, technically they got quite a
bit of area there that bypasses at the
top. So, this little bit here is not
even as much as what that is, and that's
going around the evaporator. I think
what you're going to what you're going
to find out is once that uh reheat valve
energizes, that's when everything's
going to go to crap. What sucks is that
you can't hardly get into it because
everything's in the main path. And so
for you to get in there to feel what's
going on, it's nearly impossible. One
valves were bypassing 100%. Like right
now, we're good. Evaporator temps 49°.
Looking good there. Discharge temps 130.
Looking good there. You know, high
pressure 450 something. Looking good
there. No major issues yet. Temperature
is 84. Relative humidity 67. Supply air
74. So we're we are bringing the
temperature down. That's because we're
purely running in air conditioning mode.
Pressure starting to jump.
You don't want that outlet air to get
too cooled because well, here's outlet.
It's 89. So that's not horrible. You
want to keep it, like I said, you don't
want you only want to be you want to be
a degree or two above it. That way you
don't evaporate your water which creates
more humidity. Turns 84. I think 84 85
is what they're running here. I think
what we're running into and we should be
able to come over here to the condenser
outlet tower out. It's not really hot by
any stretch.
Tower in.
Pretty dang cold actually.
About feels the same there. You got like
a possibly a screen or something going
on here. Screen. Yeah, most likely a
screen. I don't know if that's ever been
checked. So, if you look here, 85 and 89
out. So, we're actually gaining some
water temperature on our pool.
Compressor still holding 475, which
we're good there. But our problem lies
with that reheat. And it should tell me
reheat here in a minute. The mode we're
in. See if we can escape out of here.
Set points. Here we go. Now, this this
keypad needs replaced. Humidity is at
45. So, it's set for 50%. I think it was
right. Yeah, right here.
And it kind of wrote here water 86. So
they've actually lowered it 86 87. Here
we went 8485. So they've lowered it one
degree. I don't know if I ever made the
video actually. I made a video of this
and I don't think I ever used it. Here's
some selectable options. We had to go
into the code there. Auxiliary heating
enabled. Yes. And is it working? Yes.
Yeah, that valve I said
>> yeah,
>> that wouldn't have done it after all. I
got looking a little closer. I thought
it would have that actually would have
just made a problem if it was running in
cold weather.
>> Okay. So, I was hoping maybe I found
something. It wasn't, you know, it
didn't didn't help it none if it was
running in the winter, but it can't run
in the winter cuz you don't have a
Yeah.
>> Uh, so I what's happening is it's going
into reheat and that's when it's
actually tripping high pressure. Uh,
right now it's not doing nothing wrong.
It's actually air conditioning and it's
actually keeping moderate temperatures.
But when it did the reheat, that's when
the uh temperature went up crazy high
and then I tripped out on head [music]
pressure. Was you getting alarms on it
when when uh it was acting up?
>> I didn't even give it let it get to that
point because the temperature was going
up so much so quickly. I went it ain't
working right. You noticed it
immediately. Burn anything up. No, like
I said, within minutes,
>> okay,
>> this thing just kept going up and
temperature went down, but the air
temperature just went freaking through
the roofs. I I didn't even give it the
opportunity to alarm out.
>> Okay.
>> And again, that was just me here
yesterday.
>> Yeah. Right now it's not running the
reheat or yeah the reheat right now
which it probably should being and this
heat pad needs about replaced. I don't
know if I can I don't know if I can
clean it. It's about to the point where
it doesn't want to hit it just right on
that center damn thing. I don't
>> so discharges around 440. We're good
right now. But it's not running and
that's the reason why I left open that
thing down here. This is the reheat. The
way that it dehumidifies without
overcooling it is by running hot gas
into this coil right here. It's not
doing it now. I did it earlier, but it
ain't doing it now.
I mean, the thing I changed basically
sends the refrigerant one direction or
another. Okay, the belts. I changed
these back in 24. They take care of
those themselves.
There's quite a few factories up here.
So, he said they might have some. Yeah,
I changed them things back in September
of 24. So, it's a year and a half,
almost 2 years old. I like seeing them
done every every year. These things run
non-stop to to look at it like that one
there is looser in a goose.
Um, but the biggest thing is when you
look at the inside here, that's that's
so rounded. It's not gripping. And
there's a little bit of wear inside that
pulley there. Oh, and there's a bunch of
wear in here. Oh my god. Both pulleys
need replaced. You're just destroying
the new belts. Oh god. Yeah, these
pulleys need replaced. They're not going
to do that either. Jesus. But that
wouldn't cause your head pressure to go
high. Well, you know what though? If
your airflow sucks. Well, either way it
goes after it gets done with the
condenser, after it gets done with the
reheat, it goes to the regular
condenser, I think. Pretty positive.
Yeah, it goes in there one or the other.
Comes out of there. I don't know if it's
smart enough to automatically modulate.
Yeah. And then that's when it goes
through that little weird valve there.
Maybe leaving that open was probably the
way to try to save its ass. Yeah, cuz if
you don't have enough air flow and
they're running through the reheat, I
guess it depends if you ain't get enough
air through the reheat. Well,
surprisingly, there's a big industrial
place down there that had these belts.
So, we got lucky on that. Heck, they
even had the nice uh posyillock polers
and stuff like I've got a selection of
them. Most nobody has those. So, we'll
get these on there. They'll be good
enough till they wear them out because
of the pulley. But those pulleys need
replaced. I told him that. So, we'll
have to see whether or not they decide
to do anything with that. Have to get
some measurements on it. They can even
replace that themselves, too. I don't
really care. I just want it to work.
It's all I care about. Just like And
just like that, we got those on there.
Yes, you definitely need to loosen that
up and get them on there without rolling
them on cuz you technically break the
belts. Marked on there that the pulleys
are worn so somebody can say, "Yeah, I
told them right back on that date."
Let's put it back together.
See how it acts. Um I'm hoping that we
were losing enough air flow that
that's our whole problem. Let's see how
much noise this makes.
Oh, look at that.
No squawk at all. Oh, wow. You can see
some major air flow difference. Hear it.
Plain as day.
Listen to this squealing. Oh my gosh.
That's 10 times air flow. Oh my gosh.
Yeah, I think that might be our issue.
I think that might have been our issue.
He said he didn't even notice that
happening. Cars tripping out.
Oh, there she goes.
Okay, I've got heat on this reheat
valve. I can feel it plain as day.
Nice and hot. Don't really care for it.
Don't really want to hold on to it.
Let's go to the outgoing side.
Outgoing side ain't too bad.
Let's see. Let's go ahead and put this
thing back together.
There we go. 72% humidity. 83 84.
We go.
Okay. So,
now you can't replace the keypad. All
you can replace is the liquid crystal
display.
Well, I'll clean those up with some
rubbing alcohol. You know, what might
actually pretty decent [gasps] is lens
wipes. Good enough for your lenses.
Should definitely be good for that. Not
for contact lenses. Go figure, right?
Those sides here. I should get them
clean.
Not a lot to be seen. Sometimes this
works, sometimes it don't. It's just a
crap shoot. Sometimes clean inside of
the lens while we're at it. Right. There
we go. Just like brand new. All right,
let's put it back together here and see
what happens.
You have to press hard on that. Press
enter.
That works real great. These buttons
over here work real good. Be nice if I
could switch these buttons for these
buttons. Maybe see if that makes a
difference. Oh, great. Now they don't
even want to work. That's great.
Head pressure fault. That's great. Call
for dehumidification.
Blower on. Head pressure control
modulating 100%. Head pressure control,
which would be that most likely that
valve coming back.
Um, could also be the one going to the
condensers. I'm not sure which one. So,
that button works now, but the other one
don't want to work. Freaking garbage,
man. I hate dealing with this
Whatever's going on, it's just basically
slamming it right. Oh, it went way
stupid high and it tripped. So, it's
really seeing it, but it's like it's not
it's not getting wherever it needs to
go. Something's not right. Something's
blocking my refrigerant path. How you're
supposed to diagnose that when you can't
even get inside there is beyond me. It's
got an idea. We're going to use the
probes there. Put them inside there. And
we are going to see where we're losing
uh where we're basically getting too
much heat. We can do it in and out.
We're going to clean it up here with the
uh brush wheel. We're going to see where
the hot gas is going. Is it going
through this side of the valve or the
other side of the valve? We're going to
put the suction temp on the reheat side
because reheat would be kind of like an
alternative.
And we'll put the discharge or the high
side one [sighs and gasps] on the one
that would go to the normal condenser
cuz that's just what you'd normally do.
You go to the normal condenser. So there
we go. Both of them got some juice on
them. Now I've got four other ones I can
go grab. We'll see how these do first.
You know what? Screw it. Let's go grab
the other ones. Okay. So, we've got some
brand new ones here. Then I've got this
one here. I hate the way they all get
beat up. Look ugly. That's the only
thing bad about yellow. Now I can go
through and find them all. 1 2 3 4 5 six
of them. I don't think I have six, do I?
Okay, so here's an update of what's
going on here, cuz this is a totally
flicking joke. So that valve that I
thought I screwed up on, which I kind of
probably did. When I close that off,
that was causing my discharge to go
crazy high because the other valve
beside it that's supposed to do all the
work, it obviously ain't opening. So, we
open it back up. Now, it runs without
tripping head pressure. Look, it holds
right in there at 347. Now, this one
right here, I was looking at the wrong
two when I was when I was doing this.
This is my reheat, 88°. 110 is my
regular coax coil or my flat plate,
whatever you want to call it. That's my
condensing temperature right there, 111.
So, that other valve probably needs
replaced. I don't know why I'm on that
refrigerant. Not that it really would
matter.
Yeah, let's change that to 4010A. There
we go. Select.
Okay. So, either way, um,
yeah, that's what's going on. We're not
tripping out no more. We got good air
flow. Our humidity is coming down. So, I
mean, it's doing everything it should.
So, we're back to the original reason
for being here, which was why did the
room get so flipping hot. I think that
valve over there, which is wide open
right now, is what's doing it? Because,
you know, we're at 84. That's returns
84. It should modulate down. Now, that
valve don't modulate down over there cuz
you can see that it's freaking way up.
This is closed and that there's open
right now. It's wide open. So, it's
letting should be letting some really
hot freaking water through
which
[music]
Yeah, you don't want to hold on to that
one. And this is heating water coil out.
I can hold on to that one now. And so,
they're yanking a crap ton of heat out
of it. Like I said, we're doing full
bore there. So, we got to watch it and
see if this stupid thing modulates shut.
If it don't modulate shut,
cuz they had shut [music] down the pool,
too. the when it somehow kept the
temperature. Okay, our humidity is
getting dog on close here.
Um, your sensor readings, which is
supply air coming in at 87,
inlet, outlet. So, outlet, you know,
sensors, that's for pool. So, we're
still putting heat into the pool. 345
discharge temp 144 which this one here
doesn't say we're that hot which really
kind of makes me wonder how
should be 115 actually I don't
understand how that's accurate
cuz that is un well the pools might be
stealing some of it too I probably could
put another probe on the the compressor
it's just so hard to look at your
freaking gauges [music] and do all this
crap you our humidity we're bringing her
down quick There's 87. So, we should
hopefully the inlet we're right now our
inlet's 85. So, this thing should come
up then that thing should modulate down.
If it does, then I don't know where to
go from there. Okay, our sight glass
looks fine. It's completely
completely full. So, that's good to know
that I got a nice green indicator there,
which I think I replaced that. So, our
sight glass is full. That's good. Yeah,
we're not getting no reheat up here at
the top.
Yeah, we're getting water. You can see
the water down there.
Yeah, our our uh reheat here is
completely
completely not hot at all, which our
gauges should show that. And they do.
87
at three heat 109 is the condenser.
I would be curious to know what my
discharge is. Kind of like to see that.
But we're at 53% humidity. So, let's
have a we have a 50% uh humidity
setting. This was the old one was 87 for
the air. Now it's 84. I guess water is 8
was 86. Now it's 85. I don't know. At
this point, if it starts to modulate up,
if it starts to hit temperature, then I
don't know what to do after that. As of
right now, all I know is I found that we
had a problem with the modulating
sensor, which I was going to try to find
in the book, which is real thin. And
then they probably aren't going to want
to replace it, so it'll work without it.
Just ain't the way it needs to be.
