Hello All, I have a 5 or 6 year old Mount Vernon Quad that is having feed issues. The auger seems to get clogged after about an hour of running. I’ve checked the basics like the vacuum switch, snap disc 2, the auger movement, the voltage out of the controller and everything seems fine. I’ve pulled the auger (checked the set screw) and cleaned the hopper but none of this solved the problem. After about an hour the flame height is all over the place and often the stove will shut down but the command from the controller telling the auger to move is still present. But no pellets are dropping. I’m using Lignetics pellets in the white bag but plan on switching bands tonight. What I’m I missing? Any idea’s would be much appreciated. Also should the gasket on the glass door make a complete square? Mine only has the gasket on the two sides and the bottom, not the top.
