John E Bellevue , WA January 07, 2022 Appliance: Model GE MONOGRAM My ge display showed “f3” which i read meant the control panel had shorted out that seemed to be the final straw for tiring microwave I looked on the Appliance Parts Pros website and they carried the complete control panel assembly. While I was fixing it, I decided to also replace the dead light bulb and the door switch and the cracked turntable. The microwave is a built-in model, so replacement is quite expensive. The actual repair was pretty straight forward and took me about 1.5 hours. The microwave works great now! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
