Thomas S Minooka , IL November 22, 2016 Microwave did not run and wall oven would not heat I used a simple volt meter to check continuity on the thermostat and switches. I found a switch that was not working on the microwave and a thermostat that was not working on the oven. Simple fixes that cost 30 bucks if you are willing to open it up and look. The oven was a little more difficult, but only because I had to pull it out of the wall. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
