system: - stand alone direct vent gas fireplace (stove) - 2 wire system - pilot light - thermostat controlled
the thermostat stopped turning on the fireplace. the fireplace starts and runs fine using the manual switch on the front of the fireplace. i am getting 464 micro volts at the thermostat. even when i manually jump the 2 wires at the thermostat, it still does not start the fireplace.
any ideas would be much appreciated
