Charles M Centreville , VA August 25, 2015 Appliance: Model GE PROFILE Ge microwave stopped working showing an f3 error and randomly beeping We first called a repairman, who wanted $80 just to come out. Said they "didn't have much luck" with such problems, and tried selling us a new microwave. So I did some web research, and the consensus was a short in the touchpad. ApplianceParts not only offered the best price on replacement, but offered technical assistance. Removed the control panel, replaced the touchpad, and repaired the problem in less than an hour! Best $80 I've spent:-) 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
