We are getting Err 22 on our American Standard thermostat and the hear / air won't come on. It was just serviced and working a few months ago. The thermostat is hard wired into the wall so it's not a power / battery issue. I checked the fuse box and all are in correct position. Any suggestions?
I see so many problems with these. make sure your thermostat is set to heat. if its hard wired simply turning it to the degrees it shows a bit past, should turn it on.If not check the heat source for any blinking lights which means a malfunction on the heaters it self... If you checked fuse box sometimes to flick the switch to off and back on does the trick to reset it.

Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...
SOURCE: American Standard Gas furnace acting weird
I am concerned of the readings you have given. 120 volts to ground, but 168 volts to neutral? And having 10 amps of current at the "ventor", but only 1 amp for the whole furnace worries me, because power for the "ventor" comes through the furnace.
You should not have 168 volts to anything! Unless somehow 240 volts is feeding the system, and there is a medium resistance short somewhere.
The controller boards are sensitive to AC polarity (if you will). Neutral should be tied to neutral on the board. You can check that by testing for voltage between the neutral terminal and chassis ground (assuming the chassis is properly grounded.). The hot leg of incoming power, which should be 120 volts, should be connected to the terminal that says 120 VAC.
If your getting 168 volts AC somehow, then something is wrong, and you need to disconnect power from this unit until you find the cause.
As a heat-A/C tech, you should know the sequence of operation for all furnaces is pretty much the same. The boards, while manufactured by different manufacturers, all operate pretty much the same way.
Let me know your findings in reply and I will attempt to help you more.
SOURCE: I have error codes flashing
Error codes from American Standard Pub 18-HD32D2-8, which is a one-sheet document that came with my American Standard air-conditioner:
29 = not listed
129 = not listed
80 = HPCO Fault - problem is in outdoor unit - Desscription: High Pressure Monitor Fault (hard lock out, cycle power to reset)
91 = Communication Inactive Fault - problem is in air handler - Descriptions - COMM Bit Master Clock Error, COMM Heat/Cool Demand Error, Serial Motor Communication Inactive Error
91 = Communication Fault - problem is in furnace - Descriptions: Blower motor no COMM response, Inducer motor no COMM response, Loss of heat/cool demand, Loss of clock signal
91 = Communication Fault - problem is in outdoor unit - Descriptions: Loss of Heat/Cool Demand Message (COMM), Loss of Bit Master (Clock Signal)
91 = Communication Fault - Description: Comm line is dead and no bits have been received.
By the way, I do not recommend American Standard. I've had mine 14 months and it just blew up - the entire control panel blew. My advice to you - think about a different brand.

I am experiencing the same error code on my American Standard AC and according to Public. #18-HD32D2-8, error code 126 is in the Equipment Change Alert Group and the description says "Equipment does not match value stored at startup." Then, in a footnote, it says "A device has changed since Auto Discovery (See Installer Guide *S& 0706 to reset)."
This is all Greek to me so I'm calling my AC guy. I can tell you this, however. I bought an American Standard AC brand new just two years ago and one year ago exactly, it blew up. American Standard replaced it. Now, one year later, more problems.
I question the quality of American Standard and would not be inclined to buy this brand again.
the dual run capacitor is bad located in main panel of unit size of small red bull can it will be swelled up on top indicating it bad get on at electric motor or electric supply house most ac stores wont sell it has a rating like 35/5 370
