i own a quadra fire Santa Fe and have used it for primary heat for 6-7 years now. We burn 3-4 tons a year and haven't had any big issues with it. My problem is everything is working fine but the pellets are not lighting. It's turning on and feeding pellets just fine but the burner is just not engaging. Yesterday I noticed that it was shutting off and turning back on very frequently which is very abnormal. It usually runs pretty long periods of time. Plus it's fairly warm out here right now. I guess my question is, could it be the thermocouple or maybe the control box? Any help would be very much appreciated. Im a carpenter and a heating guy!
