I have a propane fireplace that wouldn't start. Cleaned the thermopile and thermocouple and got the pilot to work fine. Then the main burner wouldn't light from the thermostat--it only lit if I jumped the terminals at the fireplace with a paperclip. Then it ran. I could turn it OFF from the thermostat, but not back ON. So I removed the thermostat, connected the wires -- that would turn the thermostat both off and on. So I replaced the thermostat, and still have the same problem-- the thermostat turns the burner off but not on.
So what's my problem? Is the thermopile or thermocoupler bad? Is there another bad switch in the circuit somewhere?
