Yes, much about nothing, but the existence of the dehumid oddness
will make the old gentleman happy! It just has to get back to you in some good karma way--it
might be a good time to buy a lottery...
Sorry, I'm not seeing what you're
seeing. My page 6 has controller
in middle of page--right side has
damper connections, bottom has
controllers two 24 volt connections on right, equipment...

This is my first encounter with
this model of controller, but from
the above manual, it seems like
Owner said brand was Braeburn.
But at the control, there were only
R, G, Y, & W from both stats.
I believe control is seven years old. Again, jumpers on pins on control were all properly set if...
Bryant Zone Perfect 2-zone.
Install manual is readily available with simple google search.
Manual says LED, designated 'L',
"Displays ON when reversing valve is energized."
Except it is not a...
Back from this morning's adventure.
Nobody home so I laddered it over the fence.
Reminder--this was a rental.
I looked at the run cap. It measured 41 mfd,
labeled 40 mfd. Compressor said 35...
Thank you everyone for the thoughtful replies.
I have a message into the shop guy to see if he
will let me in (It is Saturday.) to get my van/tools to go check out
electricals again. I thought...
Heat pump mode.
TXVs inside and out.
In A/C mode, SH about 17, SC 12.
Heat mode, seems okay for about 20 minutes.
Low side 36 F (55 outdoor ambient, 64 indoor drybulb)
The remote on mine died a few days ago after about two years. New (tested) batteries.
Just nothing on the screen. But I am not switching brands--already ordered another
one unit--scale & remote.
I am in this tool forum today looking for recovery machine recommendations.
I have TWO Appion G5 Twins. When the first one died, I needed one fast and
couldn't wait for parts, so I bought the...
I have developed a habit of testing/tightening
Shrader cores on units if I have had my gauges on
them and noticed some time ago that Bryant package
units seem to have a weird core that my tool...
This is for my HVAC brother, so I have not seen the unit.
But he wants to know the tonnage of the a/c as he wants
to install it tomorrow.
(And he's too lazy to read HVAC-Talk. :)
Okay, back from my day. The heat pump was the first call, about 7:20am, because the lady
had said it made the dreadful noise only when it was cold. I got there and ran around to the
Yeah, I was thinking that were there a problem with it being STUCK in defrost,
they would have likely complained about the poor heating. They didn't. Of course,
they DID say it would stay on for...
This unit had only a schematic and some charging charts,
nothing too useful.
Elsewhere on the forum, I read that Trane heat pumps tend to
use an outdoor...
(The Search did me no favors.)
I know a lot of gas valves on condensing furnaces, especially the ones
with sealed burner boxes, had/have vents on their gas valves, but would
it be a mistake to...
OH!!!! I see.
Learn something every day. :)
Thanks for the heads-up. It won't let me edit, so I flagged my own post.
Maybe your browser cached my old profile?
Anyway, thanks again.
Yes, that nicely sums up the two kinds I've encountered.
Thanks for the attempt, Rundawg.
The address in my settings is correct.
I've never seen one of these units before.
The ignitor was in a big separate cannister, not on
the main board. The...
I was troubleshooting it this past week and noticed it goes into
lockout after just one FAILED ignition attempt. Lots of dip switches
on the thing, but customer was not given manuals for it. (Not...
Not the the scale, the meter.
I love my Fieldpiece scale too.
(But my multimeter is starting to go blank briefly
after about three years. DS (?) 35. But I will just
buy another. Fluke products seem so antiquated
I first noticed something was wrong when I heard the compressor's internal
pressure release in heating mode.
Then I switched to cooling mode and this time watched my
gauges. Low-side dropped...
We didn't do the install and we've only been caring
for it for six months--it is an 05-- so I'm not absolutely certain
this package heat pump was never opened, but let us
suppose it wasn't opened,...
My brother does HVAC, but not this forum.
He had a problem with high superheat.
========He wrote to me (only siightly edited. He has some very
dry humor so I'm thinking the ice cube stuff is...
Look for an open safety switch.
I screwed up and broke my 3/8" today.
It is probably the one I use most.
But I am suprised to not see any replacement heads
sold separately from the whole kit, either from the manufacturer
The outdoor unit and furnace were Ruud-labeled.
But the evap coil only had a few markings on its label.
Curiously, it had no model number but DID have
a serial number:
The top line...
But the circuits cannot all be flowing the same refrigerant. They must be separate.
How is that accomplished? A diagram would be good.
Okay, I googled.
Sounds like a variable speed motor.
But I'm really asking about the pumping of refrigerant with multiple circuits.
Oh, of course.
(Waiting for kindly elaboration......or a link or something. Thank you.)
My google and search skills are not turning up anything about how these
things work in regards to multiple heads. I'm thinking they don't
have a compressor for each head/circuit, but I have no...
I was rushed so I didn't really pause to check the schematic for clues
on this, but this unit--which has two compressors and two condenser
fans--would periodically stop one or even both of the...
Just wondering if anybody has experience with the hi/low side temp/pressure
ranges with these.
I saw one with a 13 F SH, an 8 F SC, but
the low side sat temp was, rather than a typical 38...
That might be part of my problem--I have no idea what subcooling should be for a fixed orifice system.
Any guidelines for that?
My first positive liquid-line restriction was an easy call---I had
a vacuum on the low side and about 200 psig on the high side.
But I am guessing most restrictions aren't so clearcut.
I was at the local supply house asking this question last week.
The guy is generally well informed and had just been to a class
on 407C. He said the two methods are to cut out the compressor...
If you are certain there was 24 V to the board (Y/G) and
no 24 V to the ECM motor, then it has to be the board.
I went back and installed the new factory motor this morning.
After I removed the motor from the blower assembly, I noted that
the bearings were rather rough AND the thing had maybe a...
Do you know if the new motor measured 88 ohms?
Was it shaded pole or PSC?
(Why does it seem many (?) package units use PSC
and split systems almost always seem to use
I like the lateral play idea as I already know the bearings
are not great. I can't say I really tried to wiggle it.
The new motor is due from the factory next week so I will
check it more...
I did the amp draw. 3.0 Amps. Only three wires on this motor. Speed is selected by
attaching black to one of several terminals on motor. I didn't pull the motor to check
LRA and the label was...
Today I had a blower motor that wouldn't run.
In the past, I've pretty much checked for 230V
(or 115V, but this was a package), and tested
the capacitance on the run cap, and then
called it bad. ...
"I'm thinking a heat pump thermostat that the reversing valve is energized in heating by hooking the "RR" relay up to the "B" terminal of the stat."
I'm pretty sure that IS the way it is with the...
If W closes RR, then RR2 gets closed, connecting R to Y which closes the compressor/OFM
contactor, regardless of whether the tsat energizes Y. That appears to be NORMAL
operation for this unit. ...
Package heat pump.
Product 542BU0030000PBAE (actually, first 0 is a greek phi, I think.)
I'm guessing it is a 1977, 35+ years old.
It is 2013. Sometimes you read about practices from the past and
people mindlessly keep doing what they learned 20 years prior.
I don't want to be such a victim.
After a residential-sized...
