I have a Whitfield Quest Pellet stove insert, I believe its around a 1995 model WH-Q. I'm having issues with the pellets feeding properly. When I start the stove the pellets feed for about 20 min then they stop until the flame dies down to almost out. Then the pellets start feeding again and it continues to cycle like that. I've read that it could be the low limit snap switch? or even ashed over? I've even tried to jumper past the snap switch. Even doing all of these things I can't get it to work correctly. I have ordered a new low limit switch hoping that this will correct the problem. This stove is old but it's worked great up till this year I'm afraid it may be the controller? Any advise or help would be appreciated.
