I just installed a Weathermaker 8000 in my camp after converting it from natural to propane. It seems to start up fine, but the blower runs continuously-weather burners are ignited or not. Any insight to this would be greatly appreciated. Tim

Disconnect G/Green wire from the circuit board. If the fan shuts off then it is a wiring or thermostat problem. If it does not shut off then it could be a defective fan relay.
