Amana PTC093B50AJ Electric Heat Air Conditioner - Answered Questions & Fixed issues

it may be designed for that. heating is usually low speed while cooling is high speed

The thermostat is bad or out of adjustment.

Short of gas due to leakage. Check the pumping pressure in discharge side of compressor. If it's more than 250psi, it's confirmed there is leak. Check the unit if there is any oil tracing. Remove all gas and pressurize by nitrogen upto 300 psi and find the leakage with soapwater. Arrest the leak, vacuum and do gas charging.

Sorry to read about your problem, I hope this helps you out.

You can have a couple of issue's, one of them is a reversing valve, or even a defective control.
Its takes special tools and equipment to work on this unit.

I suggest you contact a service company.

sounds like ur board is gone out and needs replacing if u dont no about these units i dont advise trying to do this trust me save urself some money and headach and call a tech

several things could be the cause but lets start with the easiest first. check the filter to see if it is clean. if so then you need to see if the coils behind the filter are clean. a blockage of air flow will cause the unit to freeze up. If the coils look dirty then you can purchase a coil cleaner (aerosol) from a home improvement store or an a/c supply house and follow the directions on how to clean. These coils should look nice and shiny. If all of the above mentioned are in good shape then you possibly have a low charge of freon in the system. In that case an a/c tech will bee required since the usage of freon is only to be done by certified techs.
Hope this helped

fp means freeze protection when gets too cold out unit comes on by itself so pipes dont freeze

in heating mode find sensor located on coil follow to board connection usually 24v and dft terminal jump out with a wire and jump test pins if goes into dft then sensor bad if not board

Hi,
Pls check the following....
1) Fix the wire connector to Reversing vale
2) Check the Capacitor if this a low capacitance or (open) not function using Multi-tester.
3) Check the Selector switch if this is not function using Multi-tester . or check the PCB Board (if electronic your units) replaced the Board.

If not yet,go to the nearest repairman to repair that units.

Thank you,have a nice day.

The important consideration is the rotational speed and adding extra horsepower really doesn't achieve anything because the motor isn't really under 'load' as it would be in say a winch. It is better to stick to OEM Specs https://www.google.com/search?q=amana+80+sse+blower+motor ..

Does the power light come on? If yes, then you can do a reset as below: There is a master switch on the bottom left of the control board. Slide that to 'off' position. Then press the hot and cold switch/key together and then slide the master switch back to 'on'. Please put your response/observation here if that does not work or there is power light as asked on top. Thanks

i'm not familiar with your specific unit but ..sounds like an electronic gas value has gone bad or has a bad connection when that happened to my friend it wasn't that expensive to have it fixed .. BYW it acted like this for a while then stopped working completely

Hi, Please hit the "constant fan" button until the "on" button is removed from your Amana screen. Thank you.

bad control board

blower capacitors or motor bad

you will need to call for service. if it needs freon you cannot recharge it freon is expensive and requires a license.
