David F Rutledge , GA April 18, 2020 Run away temp on lower oven (f10 error code) Replace relay board. This part wasn’t too difficult, remove doors, racks, and 2 mounting screws on the sides. Then slide the unit out until you can access the top panel. Remove the 5 screws on the panel and then the panel. Unplug the board, remove 2 screws and release the clips holding the board board. The oven is 6 years old and the new part is a newer revision than the old part so it should last longer. The hard job was replacing the temp probe in the lower oven. The wire isn’t long enough to unplug from inside the oven so the entire unit must slide out to access the rear panel. Once’s the panel is removed it is easy to unplug the old and plug in the new probe. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
