Kathleen W Kingsport , TN July 02, 2022 Appliance: Model FRIGIDAIRE PLEB38T8CCB The upper wall oven didn't heat. We talked to Gaye on the helpline after pulling the unit out enough to remove the metal shields. He was super helpful. He recommended we test the Thermal relay and the cooling fan motor to make sure they were working. He told us how the control board could fail because of using the self-cleaning mode, which was when it had stopped working. If those two were working, it would most likely be the control board. He checked the wiring diagram to make sure we would be ordering the board for the upper oven. He gave us part numbers and prices for all the possible parts we could order. He was methodical and took his time to make sure we understood what to do. We tested the relay and motor. They were working so we ordered the control board. It came in less than a day, we replaced it and the oven works again! Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
