I have a model 35 Osburn pellet stove from SBI. For awhile now when I would go to start the stove, the pellets would feed into the burn pot normally but, the ignitor didn't seem to heat up enough to actually get the pellets to start burning. Now the ignitor element wont heat up at all. I'm guessing I need to replace the ignitor but is there a chance that it could be a control board issue or one of the sensors malfunctioned? Thanks.
