OK. Had a brain cramp. Power was off on the VAV. Got it resolved. Thanks for your consideration.
Coolairman.
I just replaced a VAV control module Alerton SD2A, which I'm told is obsolete. The vendor sold us a VAV-2A-E. All terminals are the same, set the dip switch appropriately. Went through the procedure...
Just make an oil trap, it'll be ok.
Does anyone know the 3 digit password for the Danfoss VFD for the compressor on Annex package unit?
M/N AHU-E-03-C-HR-HE-AM16 S/N 2333-01-1214.
You don't have floodback with 61* superheat.

Stupid costs extra.
Thanks for the advise.

I would see if I could find a working display module, but it sounds like your vfd has failed.
Good luck.

I changed the controller and it appears to be working, but some of the values are not showing on the graphics page. I'm new to this system so I'm trying to move up on the learning curve. I tried to...

they are not in parallel to the compressor contactor-they are in series. When one of the safeties opens, the logic in CTD opens that switch. It is pictured as normally open but its actually normally...
To your original question "What are the true symptoms of a bad TXV?". A bad TXV will not control superheat.
To troubleshoot a TXV- make sure your air volume is right. Clean coil, filters, fan...
I have used the Lucas Milhaupt alloy on an Aqua Snap copper to aluminum joint and it held. You have to get it super clean and be very careful with the heat. I wouldn't use oxy acetylene.
You have way too much superheat for comfort cooling-the evaporator coil is starving, and you may be overcharged-find your restriction.

I'm working on a Carrier 38APD40... 40 ton split system. The B circuit check valve makes a high pitched noise when compressors cycle off and refrigerant moves through it. It is a Carrier part...

Does anyone know of a clever way to remove the access plug for the internal oil filter on a Carrier screw? I've put around 300 ft/lbs on the plug and it won't budge. I think somebody put thread...
Thanks-that's exactly what I needed to know.

Put a 1/4" gauge tee in your external equalizer tube and measure your pressure there, it sounds like there is a restriction in that line. I've seen them clogged with solder from the factory....
Does anyone have a service bulletin RTAA-SB-5 in PDF format they could forward to me. I would greatly appreciate it.
Thanks- Coolairman
If everything else checks out check your current value in the vfd config, it may be lower than the motor nameplate, that can cause an over current alarm.
That's another reason most manufacturers recommend NOT burying line sets.

Was not sure what to call it, but your description sounds better-profile updated.
Thanks

Looks like early 70's vintage-you may want to check the expansion valve for capacity. Personally I haven't seen a Chrysler Airtemp in close to 30 years.
Good luck

Thanks Balibe, I'll try that on the next one.
