Hi, I have a Quadrafire Castile pellet stove insert. I bought it new in 2006. Original owner. Never any problems with it until this week. Ran perfectly every winter, then one night this week went to turn on stove using wall thermostat and there was nothing. Not a blinking light on control box. Not a fan stirred. No noise. Nothing. I checked the main fuse near the control box. It's fine. I checked to see if the fans still freely spin. They do. I checked to make sure my wall outlet still had power. It does. If a snap disk is "blown" would that completely shut off all power to the control box? No lights at all anywhere? Is my first step to just replace all snap disks and hope that's the problem? That's certainly cheaper than ordering a new control box. Also, there's a third snap disk right? I found the two right near the control box. Where's the third one? What else can I check before calling a technician to come look at my stove? Is there a way to check snap disks if I have no power anywhere? Thank you very much for any and all suggestions.
