I just purchased a home in which has a beautiful Mt Vernon Quadrafire pellet stove. Its an older model, not the AE. It appears the previous owners did not take care of it at all. After cleaning, replacing gaskets, a new ignitor, new control box the pellet stove was working pretty good….up until this weekend. Plugged it in, set thermostat to call for heat, ignitor gets red hot, but no pellets feed into the fire pot. After going through the troubleshooting in the owners manual, I believe its the thermocouple. There is a flashing green light on the control box. Before I replace yet another part, does this sound accurate? Would a bad thermocouple cause it not to feed pellets? And since the ignitor gets red hot, shouldn't it start a fire even if I put a handful of pellets directly into the fire pot? Any advice would be great. Thank you
