Andrew D Lawrenceville , NJ February 02, 2015 Microwave would not power on Through a little research I determined that the primary door sensor on the microwave was bad. AppliancePartsPros got the identified parts to me quickly. I then installed the parts, the microwave worked great, and best of all I saved a couple hundreds bucks by not having to buy a new microwave/pizza oven. 44 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
