Hi Dave, I have a QuadraFire Mt Vernon E2 pellet stove. It was working at the start of the season in mid-October. The following day was not working. Started the troubleshooting process. I have a blinking amber light. Research suggests a bad thermocouple. However, don't see a thermocouple on the schematic or listed in the parts section. At start-up the combustion motor starts, the light is blinking green and then after approximately 45-90 seconds, the light blinks amber. I thought I had fixed it and it was working briefly, bu the problem above occurred. I have replaced every component from the snap disc, to the vacuum switch to the control board to ignitor and exhaust probe. Also blew out exhaust ducts to the outside with leaf blower, cleaned the pellet stove. The pellet stove has a remote function which we do not use. Therefore, I have it in the "ON" position (or manual). There is one thing I recall and that was a wire that was underneath the pellet stove that hung down and laid on the floor. That wire is no longer there for some reason. My thought was this was the thermocouple. Any suggestions on what is going on would be greatly appreciated.
