Homer G Palm City , FL June 13, 2021 Oven would not pre heat to required temperature. I read that the controller and probe controlled the oven temperature. Also read if replacing controller you should replace the overlay. So I ordered all three parts and installed myself with no problem. I took a photo with my phone prior to unplugging wires so I knew the right way to plug the wires into the new controller. Works like new. Only need a nut driver and screwdriver to repair. Job from star to finish approximately 30 minutes. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
