I have a Englander 25 pdvc. It is not burning hot as for the pellets seem to be coming into the burn pot slow. The auger tube is clear and the auger is tight to the gear motor. I am wondering if it is just the motor is weak or the control board is sending wrong currents to the motor. As I look inside the hold box I watch the auger turn on different settings. It looks like on 1,2 it only moves about an inch and on higher settings maybe 2 in. It is hard to judge just how far it moves so I am asking for someone elses opinion on just how much it should move. I am talking about the top auger as the bottom seems to be running fine. Thanks for your help.
