Compressor keeps shutting down - Amana ABC2037TWH Air Conditioner

home compressors should shut down at 100 to 110 psl
replace the electrical control unit on the compressor

The thermostat has a differential built into the temperature sensing operation. The differential is normally a degree or more. If the stat shuts down at 72 degrees it should not start the unit again until the temperature in the room reaches 73. If the AC runs and cools properly until it shuts down, I would check the thermostat. The AC can not restart immediately after it shuts off because the pressures in the system are too high at the compressor. It takes a few minutes for the pressures equalize allowing the compressor to start. If the stat tells the unit to start under high pressure, the compressor will shut down on overload. It will start and run after the pressure falls enough for the compressor motor to run.

If the compressor overheats, the clixon circuit will shut off the power to the motor to prevent damage. Then when it cools it will close the circuit and the compressor will again run to only shut down again.
The suction line going to the compressor should be cold - the cold gas returning to unit cools the hermetically sealed motor. If that line is hot you may be low on refrigerant.

Your Dehumidifier may have a low pressure switch or a compressor hi temperature switch, if the system is low in freon it will shut the system off to keep from over heating the compressor.

maybe your freon is low if it is you know becuase the compressor will come on and very sune after it will kick out. if not and the compressor is running for a long time before breaks but its still not cold the compressor is weak.

Hi, This must be a heat-pump if you are using the outdoor unit for heat. There are a lot of things that will cause this compressor to shut down. Does it shut down and come right back on, or does it stay off for some time before it restarts again? This will help in solving this problem if I know. If you are inclined to do this, pull off the compressor panel and when it shuts off carefully touch the top as it could be hot, and tell me if it is very hot? Try and time it to see how long it takes to come back on. If it goes off on internal over load, it could take some time. Try and set your thermostat to emergency heat and you should have heat strips that will come on to keep you warm. Do the compressor check for me and tell me how hot it is and how long in between cycles. I will be waiting for a reply.

PS do the check before you turn the stat to E.Heat.

The compressor itself sound like it is bad. You might see what it cost to repair it. It might be cheaper to get another one...keep in mind if you do a lot of work with it that a 2 stage compressor will cool better and you won't have this type of problem again.

replace your compressor relay. that's what goes wrong 99% of the time

well most unite will go to 54 degrees but 43 that coooool man what complain about. the compressor dose shut down at certain temp so as not to turn into one hunk of ice. that what they are design to do.

Most Likely Low on Freon. Low Pressure switch shuts That Compressor Off.
