Justin B Snohomish , WA May 22, 2018 The door latch switch on our Kenmore microwave was not working properly I took the microwave case off and checked each switch after it started turning on when opening the door. One switch had shorted out. The switch board had a couple parts which broke as it seemed to be a bit brittle so I replaced that as well. The microwave is back to normal. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
