Question about Heating & Cooling
Arctic King model MWF1-05CM when set to either cool setting on any temperature setting blows cold air for a couple minutes then switches to very very hot air for even longer than it was blowing cold air. I've only had this unit for about a year and it has been doing this ever since I first started using it.Being unknown as the hottest bedroom in the house just makes this even worse than it appears.

Heat pumps have saftey circuits that prevent liquid flooding of the compressor. Inadequate airflow across the evaporator in cooling can trip this circuit. Have your package unit serviced with particular attention to cleaning the evaporator coil and be sure your filters are clean and changed frequently in the summer months. Hope this helps GL!

Check to see if your outside unit is running. If not, check the breaker. If it is running you may have an issue with the reversing valve. It looks like three lines coming out of the top and one on the bottom. Trace the wires back to see that they are tight and secure. Of course, TURN OFF THE POWER first. good luck.

Your unit may be going into a defrost cycle. If so sounds like a bad defrost board. It sends a signal to electric heaters inside to come on. Change board and sensor
