I have a Quadrafire classic bay pellet stove. It started struggling when the stove met temperature and would periodically require a reset due to shutting down. Almost like a brain fart. Today I cleaned the stove and when I restarted it, it was not dropping pellets. The call light is staying on despite the thermostat being down all the way. The thermostat doesn't seem to work at all and was no issue prior. The call light remains on even when the thermostat wire is removed from the back of the unit. The exhaust fan is running, but nothing else happens. Also if you hit restart nothing happens and the call light remains on. Any advice?
