Matthew B Gilbert , AZ December 01, 2015 Microwave would not heat Initially the microwave would cook normally and then when you open the door it would turn back on. This would happen intermittently. After doing that for a while, it stopped cooking entirely. The timer would count down but no cooking. I had to also buy security torx bits to get into the microwave. I found them at my local hardware store. After taking off the case I shorted the HV capacitor with pliers. There were no sparks. The replacement was easy. They just disconnect and pop out. The bottom switch tested bad. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
