What is the voltage for amana comfort zone 12m32pbeh

4 ton

Hi, when you are running it in the cooling mode, leave the exhaust open to remove the condenser hot air. If you want to run just the fan to circulate the air you can close it.

By "outdoor unit", do you mean the compressor? The unit you describe is a window-mount, single-piece a/c.

Failure of the compressor could be:

Disconnected/damaged power wires.
Damaged current protector.
Defective control board.
Seized compressor.

bad motor or capicitor

is it a split system? majority of problems, lets say 95% occur during install, u may have a leak! A pinhole at that, but maybe installer missed it, your out of labor warranty, call a 3rd party contractor and have them inspect it!

-AC = no power

Check freon, you will need guages on the condensor, also make sure the cond, outside unit is operating

Power coming from circut board? If yes, check the capacitor. Low voltage fuse good? Transformer good?

Check air temp out vent should be approx 20 degrees colder than room temp if it is your unit is too small for the amount of space you are cooling.Rule of thumb 1 ton(12,000btu's) for every 400 sq ft of uninsulated space

Is the blower running? Sounds like unit is tripping out on high limit safety switch.
