My stove is having issues with keeping a steady supply of pellets entering the burn plate. All systems seem to be in operating order--augers rotate as they should. I replaced both motors on 12/1 and until the past few days they worked perfectly. When it does stop feeding, if I take the upper motor and wiggle it and poke the pellet feed entry in the hopper the supply restarts. And 15-20 mins or so it does it again. One thing I noticed when I did a reset the 3rd lower button wouldn't work. I could get the numbers to change on the 1st & 2nd, but the 3rd doesn't respond. Any suggestions?
