You may want to check that the pressure switch is not functioning? Secondly there is also a thermo sensor on the condenser coil which could be faulty.

SOURCE: Reversing valve issues.
You will need to replace the reversing valve. You cannot replace the coil with a remote sensing bulb on this unit. Usually you know when reversing valves get stuck when you are having low side problems with heat working properly

Sounds like reversing valve is stuck or metering device or check valve is stuck open. If it is a scroll compressor on 3 phase you may need to reverse 2 motor leads. try tapping reversing valve with rubber mallet when running. This may have done in last compressor by sending discharge gas to suction side.

Your solution is throw that Hunter tsat away and get a good one. You need one with 2 stage heat 1 stage cool heat pump tstat. Heat pump tsta has w,y,o,g,w,rnad w2. Don,t buy one without this one it. I have been in this business 45 years and people are always getting sold the wrong tstat at Lowe or Home Depot. Those guys dont know jack about Tstats. Keep in touch Rus GOOD LUCK. Get the right tstat follow the letter on wiring and you wont have any problem.

The only unit I know that energizes the reversing valve in heat is Ruud or Rheem, All other makes energize in cool. When you switch from heat to cool htere is five minute delay. The y energizes the contactor on heat and cool. Make sure your tstat is ok. Rus Keep in touch.
