Hello there, I have a quadrafire mont vernon pellet stove that will only run for 10 minutes or so before shutting down. The call light stays on the whole time and the room never reaches the proper temperature. After it does this, I can turn the thermostat down and back up again and the stove will fire up and run for another 10 min. Sounds like maybe a snap disk? How do I go about resloving the issue?
