I have a QuadraFire Mt. Vernon Pellet Stove about 7-8 years old. When my stove starts up it skips right past the start cycle and starts feeding pellets as if it already has a fire in the burnpot. If I'm lucky and there is not too many pellets in the pot and they actually ignite, the stove works GREAT - blowers function, shut-down cycle... If they do not ignite, the pot fills with pellets and eventually will shut down. The repair guy has been GREAT and has tried almost everything and then some with no solution. He has replaced the control board - no change, thermocouple - no change, thermostat - no change. He's going to replace the thermocouple once more, then he said MAYBE he'll need to replace the wiring harness(?). We're stumped!! By the way YES I have CLEANED and CLEANED my stove. One thing I did notice this morning was the ceramic cover for the thermocouple has been warn down, and is thinner compared to the piece that is held by the stove? I saw a thread talking about a control board with lights that signal what the sensors are telling it... Does anyone have one for a QuadraFire Mt. Vernon Pellet Stove? Does this control Board have lights? Sometimes it seems to happen more when the stove is warm, but I have seen it happen when it's ice cold too. PLEASE HELP!
