Question about Sanyo STW0923H2 Thru-Wall/Window Air Conditioner
I have a Sanyo through the wall heat pump unit. When I plug it in the heater coils start heating even with the dial in the off position. No matter where I turn the dial; heat,fan, or cool the heater coils stay on. The compressor seems to be working fine and the reverse switch seems to be working but with the electric heating coils on all the time of course all I get is heat. This is also very dangerous because as I said the coils stay on even with the fan off causing the unit to overheat and start smoking. Any help is sincerely appreciated.
We use the STW0925H! in 60 rooms on this property and have encountered similar problems that were caused by weldedd contacts on one of two relays that controls the electric strip heat. They can be replaced if needed.
PTHP's and PTACs employ thermal fuses as well as a bimetal limit stat on the heating element to limit risk if fan motor were to fail and the heating element were to remain energized. It would be wise to check that both are fuctioning properly while you are servicing the unit.
