Bill D New Castle , NH March 12, 2014 A broken Microwave - suddenly lost all power to the unit Opened the back panal, requires Torex Saftey sockets, located the wiring schematic and traced the power using a multi-meter until I found where the power wasn't crossing. It was the oven heat sensor which had somehow tripped and is not a resetable part. The folks at ApplianceParts Pros helped me find the right part and I had it in 2 days. Thanks! 8 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
