I have a Pelpro Bayview, it had a acutron 2 control board that recently went crazy, I’ve replaced it with the recommended acutron 4 control board, now when starting the stove starts up fine, feeds pellets fine, ignites fine burns for a short stretch (5-10) minutes then goes into shut down mode. The Auger light flashes rapidly. I’ve checked auger, everything is fine. I never seen the auger light flash rapidly before on the old board. Is this a code for what’s wrong? What should I be checking?
