Harmon Accentra Pellet Stove Wont Start

Good Morning,

I have a Harmon Accentra Pellet stove that will shut off with no codes. If you turn the fan rheostat switch a bit harder it turns back on. I’m wondering if the rheostat is worn and it just needs a new board? Thank you for all your help.

Hello
Yes the potentiometer (rheostat) has a bad spot where there is no resistance, common problem in older stoves. A new board should fix this problem.
