Richard S Mcfarland , WI October 26, 2015 Appliance: Samsung Microwave SMH1622W/XAA-0001 Samsung Microwave Smh1622w/Xaa-0001 / : Micro dead again. How to replace Assy Thermostat;Jvm-1750. Intermittent no power to micro. Took it apart. Noticed temp.switch in series with mains was charred. Had a loose terminal on the temp switch (over magnatron). Replaced and now it works. Had to solder wires since Faston was too charred to reuse. The hardest part was locating the temp switch. There are 4 of them. Even with standard shipping the part arrived in 2 days. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
