Robert B Preston , MD February 04, 2020 Appliance: Model JKP30W0M1WW Not maintaining temperature while baking. -I checked resistance values on the temp sensor, bake and broil elements. -Everything checked out fine, so I contacted AppliancePartsPros by submitting a question. It was answered within minutes and they recommended replacing the control board at that point. -I ordered a control board and new faceplate and they arrived the next day. -I installed the faceplate onto the board and installed it. Though I didn't need it, I bought the new faceplate to simplify installation of the control board and I feel that it was worth the extra cost. -The oven then worked alright and was tested immediately by baking some french fries at 425F. The toughest part of the process was taking the oven out of the wall and removing things to do resistance checks. The control board removal and installation was actually quite easy, but the other things need to be checked first. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
