Have noticed that similar threads have appeared about Castile pellet stove insert. I have had mine a little over a year. I clean it weekly. In December it began to periodically stop feeding pellets. If I hit the reset button, it would start working properly again. I took some advice and did a thorough cleaning. That seemed to help for a week or 2. The other day it did it again and would not restart. I did a thorough cleaning again including cleaning the hopper out and cleaning the exhaust piping. I have tested the auger and also bypassed the thermostat to rule out problems there. It fired back up but I still have to hit reset periodically and more often now than before. Wondering now if it could be a snap disc. Any help, thoughts? Thanks. I have called our local dealer to try to get some advice as well.
