Heat pump compressor won't go off and red light on tstat comes on
I have a comfortmaker climate control heat pump/electric furnace. The compressor, (I think) the unit outside, doesn't seem to want to shut off and since it runs continuously even when the furnace backup (fan) turns off. I think because of this, it makes a red light on the tstat come on and it seems to make the "heat" smell hot. Not like burning wires, but just not normal, if that makes any sense. Any suggestions would be greatly appreciated.
I have search for answers here, but didn't really find what I was looking for. I'll continue to look, but sort of need an answer soon. THANKS IN ADVANCE.
