I have an amana heat pump a/c PTAC unit 14700 btu and it seems the compressor is not engaging or blowing cold air

could be a bad run capacitor or the unit needs to be cleaned take it outside and wash the condenser coil the outside coil and the evap coil on the inside be careful not to get the electric circuits inside the unit wet. I would wash the coils first and then see if it cools. Hope this helps

Unit no longer heats


If ur AC is not coolling properly thn u must go for replacing a fuse, resetting a circuit breaker or checking to see if the thermostat is set properly. If an electrical problem isn't the cause, the refrigerant may be low if the system still runs but does not cool properly. This can be corrected by having an EPA certified technician add necessary refrigerant. Most likely, if the problem involves any major part, such as the compressor, you would hear strange noises similar to those of any mechanical equipment not running correctly, or the unit might not run at all.

Go for replacing both theoutdoor condensing unit (which includes the compressor) and the indoor coil on my central air conditioning system at the same time
Matching a new condensing unit with a new coil is the only reliable way to be certain you are going to get the rated efficiency of the new equipment. Matching a new, high SEER (seasonal energy efficiency ratio) condensing unit with an old indoor coil probably would not result in optimum efficiency.

Dont forget to rate me as fixya..

I put new fan motor or heat pump now runs all time and doesat seem to heat well but line set going into a coil infurnace is hot

I would check the fan relay and especially the sequencer. I recently came across a problem with an older sequencer which had come partially apart and allowed the thermo disk to keep the fan running continuously. The sequencer controls not only the fan relay (24 volt), but the heating strips(220 volt) as well. Make sure all power is off to the unit and verify. Make a wiring diagram and take several pictures if necessary. Replace sequencer with only an Identical unit, even if you have to order it. The newer sequencers have two metal straps to prevent this problem from occurring.

Ptac heating problem

This is the service manual for this system. It might give you an idea on what the problem could be. Page 27 should be your area to start. There are two for the PTAC series. I'm not sure which one will pertain to you.

Are you getting 120 vac or 220 vac at the unit? Check the voltage at the first terminals inside the unit as well as the breaker. You should have 220 vac at the elements and you are dropping a leg some where.
