Hi everyone...I have an englander pellet stove, 25-PDVC, and the top auger will not continue to feed pellets after the start up. We have replaced everything from the motors to the control board. We just replaced the rope seal for the door. The stove will start and get through the start up but once the flame gets big, the top auger stops feeding pellets. It will turn once the flame goes out and i have a bed of coals but they dont come in fast enough to keep the stove going. Any ideas as to what could be causing this? Thank you in advance!
