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

  • Hello, and welcome to Home Improvement. It's hard to know what's going on from here; would you add some info, and perhaps a diagram, to your question? – Daniel Griscom Jan 23 at 19:56
