I have a Mt. Vernon pellet stove the date punched out on the sticker is May 2005. I have a problem where the stove thinks there’s a fire in the burn pot if the thermocouple or the stove is the slightest bit warm. On start-up, the control box light is a steady GREEN so it constantly feeds pellets, to where it cannot start a fire because of SO much fuel. I can trick it into lighting by switching it to the lowest setting to restrict the flow of pellets. The local service man has replaced the thermocouple twice, the wiring harness, and the Control Box, to no avail. He also suggested and I moved my thermostat and have the differential set to 3 degrees. The local service man has also installed a thermocouple grounding kit. I have replaced the Ceramic cover of the thermocouple because it obviously gotten smaller and worn overtime. I have also replaced the igniter because the braided cover on the igniter is chaffed down by the ash pan being taken in and out. Same problem… The local service man claims he has contacted quadrafire and has no other ideas… What is the light signals of the Control box? What should it FLASH during the start sequence? If I put an electric tester on the thermocouple, what should it read? I saw online a Mt. Vernon AE is 15mv or greater, but this an older Mt. Vernon. Before this started acting up this way, I had (I believe) Snap switch #1 go bad on my Stove, and the blower was shutting down and then the stove was over heating… What does snap switch #2 DO? Could that be causing the control box to think there is a fire in the box? Last night I noticed when I placed the heat output control knob to low - it actually turned off the GREEN Light in the Control Box. Does that make sense to anyone? What Resets the Control Box back to initial start-up? PLEASE HELP Any Questions I can answer to solve this riddle PLEASE ASK! THANKS! Mike C.
