I woke up this morning to my Harman Accentra blinking to an error code of #6. This is the second time this week it has happened and i'm not sure why. I've troubleshot everything the manual has said and its all been ok. I cleaned the stove and burnpot yesterday evening so it cant be a dirty stove. All i can think that it could be is low draft or my auger isnt feeding pellets when needed. My settings are room temp, heat setting of 75, and feed rate of 4. Does anyone have any ideas? I really dont to wake to a cold house when the winter cold comes.
