Question about Amana PTC153B50AJ Electric Heat Air Conditioner

1 Answer

Unit blows cold air instead of warm (burrrr)

Our two year old Amana PTC153B50AJ a/c-heat pump started blowing cold air. On the front of the unit after removing the cover we found the message "Electric heater has a manual reset" but we've been unable to find it. Our service person is away for Thanksgiving holiday and it is becoming a real problem with outside temps at 32 or less. Can anyone help?? Thanks.

    I have an Amana PTC153A50AD unit that blows cold air only. The fuse and fan work. The heat cartridge does not get hot or glow. The diagnostic code (one blink every 5 seconds) indicates that the board is OK. I am also having difficulty finding this particular unit listed on any Amana website.

    I am having the exact same problem. My unit is also only a couple years old. What could the problem be?

    I have a PTAC Model PTC153B50AJ unit with the same problem. The unit blows cold air. I tried Tip #1 and it still is blowing cold air. On the front of the unit it states there is a manual reset but I am unable to find it. I noticed the circuit breaker was off when we first could not get it to work. After the circuit breaker was reset I had to reset the breaker on the cord. Now all appears to function properly except the heat.

Amana Wall unit blows cold air before heating


the unit works by chilling air and the byproduct is heat in the compressor, this is used for heating in the winter and then reversed in summer to blow cold air. It has to blow cold and warm up before it can blow heat.

Heater blows hot air then keeps blowing cold air whats wrong with it


This is a heat pump so the problem could be anything related to the compressor, refrigerant circuit, etc. or the defrost control. There is usually a switch or screwdriver slot switch on the front of the unit when you take the large cover off. This will force the auxilliary heat on regardless of outdoor air temp, thus bypassing the compressor heat pump system (and costing you more to operate it.)

Heat Pump - blows heat to set temp, then off, then kicks on to blow cold


Heat pumps defrost which is the AC mode, if the heat strip isnt working during a defrost, the air will be cold, A heat pump only feels warm if the heat strips are on too! the refrigeration cycles heat output is much less sensible to our 98F skin. heat pumps that satisfy a room setpoint are working at least, all heat pumps feel drafty to most.

Amana ptac ac turn on runs short time on cool and go to fan mode warm air.


If this unit has the old style control with the knob instead of the digital control panel
then I would suspect this first. This is the first component to fail on these units. I have
replaced two already and the kit has good instructions and all components.
Takes approximately an hour to do and mount the new sensors. (The transformer is
hidden beneath the sheetmetal just below the control board). You should be able to order this kit through any appliance parts store for around 175 dollars versus almost
800 dollars for a new PTAC. Hope this is helpful.

Is it normal operation for these units to EVER blow out cold air or "nonheated" air when unit is in heat mode?


Yes. Heat pumps have to go into defrost just like a freezer when the temp gets too cold outside. The heat pump will temper the indoor air electric heat.

Heater blowing out cold air


Yes you could have a bad overload on the heater element which is fairly simple to fix. To test for this pull the heater out and get an ohmeter set it to continuity and check the continuity first through the entire heater element then if there is none pin point the overloads and check to see which one has no continuity.
