Hi, I have a GE Weathertron Heat Pump circa 1975. No HVAC company wants to work on it. They take one look and tell me I need a new system. It still runs like a tank. So the issue I have is intermittent. Occasionally the thermostat will shut off in A/C mode and the outside unit will continue to run. So I'm thinking welded relay. The relay appears not to be welded. I've had the wires pop off of what I think is the thermistor, and when i reattached them the unit shut off. Both are reconnected so maybe this is going bad? I can't find parts or replacement parts. Any help you can give me on identifying parts and where to purchase would be greatly appreciated! Model Plate.jpgRelay 1.jpgRelay 2.jpgRelay 3.jpgThermistor Maybe 1.jpgThermistor Maybe 2.jpg
Thanks. Any idea what the part is with the screw adjust that says Colder is? There is a wire off the back of it that extends out underneath the fan and looks like a temperature sensor. Here is the entire electrical and whats left of the schematic.
Sorry, now that I see this picture is it possible it's the contactor sticking?
It was changed out last year so I don't think it's likely but I will test for it the next time I have this condition.
Pretty sure that control with the dial is an Outdoor Stat, shuts off the HP if OD temp is too cold.
Does it still have the original stat? 2 stage heat/cool, 4 mercury bulbs? or has that been replaced.
You would need to find out if the 24v signal is being sent out, or not.
If I remember, those HPs had a control box that all the control wires ran to.
