Envirofire Meridian. Stove heats up and sometimes the room fan turns on and sometimes it doesn't. Mostly doesn't at this point. The auger keeps feeding and the stove gets very hot without shutting off. However blower fan still does not activate. When it does, it works well, no noise so, I know the fan is ok. Is there something other than the low limit/POF sensor that should activate the blower?
