I have had a Vermont Casting Reliance #2220 pellet stove for 19 years and it has stopped feeding pellets. It went out a couple of nights ago and I thought it just needed cleaning. I cleaned the stove but noticed that the fire kept going out in the burn pot. I can't tell if the circulation blower is running or if it is the exaust fan, but at least one is running normal. I hear it running and the flames are moving like normal when you first light the burn pot. The glass door and the door to the ash drawer both seal. The auger is turning and there is no smoke buildup. I noticed at the bottom of the hopper there are 2 doors on top of each other. The top door moves back and forth and only closes half way. The bottom door is not opening at all to let the pellets drop into the auger. Since the stove is 19 years old, do I need to get a new one or is it worth repairing? I have looked high and low for the service manual and can't find it. Is it time for a new stove?
