My thermostat sparks when I turn heat on; I tried to leave it on heat but it shorted out the thermostat. I tried another one and it shorted out the second one too.
I checked my transformer and even used another transformer.
That was not the problem
The fan works fine
The cooling works fine
I think my heat has something wrong. Is there a way to check the gas valve for a short?
If the gas valve shorts I have to buy another one right?
