Robert H Sandpoint , ID November 25, 2021 Burner going from low to high for no apparent reason Replacement was easy. Just access the controller, place the new controller next to the faulty one and transfer wires one at a time to the corresponding position and you take the old one, discard it, then install. Easy 5 minute from start to finish. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
