I live in West Chester, Pa., 30 west of Philadelphia. A ARUF018-00A-1 heat pump was installed in my condo about 3 yrs. Ago. I notice that in the summer if I set the thermostat to a random temperature such as 73 degrees the A/C kicks on and when it reaches 73 degrees the aux heat kicks on, the compressor kicks on and off every 5 to 10 seconds and the condenser fan locks out and it seem to go into defrost mode for about 10 minutes. In the winter the defrost mode does not work at all. I had the tech service the unit 3 times. The first time he replaced the thermostat. The second time he added Freon. The third time he replaced the defrost board and sensor. And after all this it still did not take care of the problem. Can you help me.
