Robert U Montclair , NJ October 02, 2015 Appliance: General Electric Free Standing Microwave SCA1001HSS01 Ge Microwave Sca1001hss01: No power two out of three thermo devices were bad. How to replace Thermostat. With no power in the unit I started to investigate. I removed the power cord and checked the supply. Then I removed a few panels from the unit. The parts are readily accessible and the wiring diagrams on the computer are very helpful. I removed the wires from each device and the probed the devices. I ordered the parts from Appliance Parts Pros online and they shipped the parts in less than one day! 11 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
