Hello, could use some help here. I have a 25 - pdvc englander pellet stove - 8 yrs old . bottom auger motor replaced Jan 2016 ... stove works perfect for 2 hrs then the bottom auger stops turning . it's not jammed at all , I can move it , it just stops turning . control panel does not indicate any E - codes so I press the off button myself . settings on control board - fuel feed 4 , burn air 4 , on temp 1 ... I believe these are factory preset . Could this be an auger motor overheating or control panel issue ? Thank you Dann
