Rocco P East Northport , NY February 13, 2022 Appliance: Model BOSCH SPEED OVEN Microwave did not heat and turntable did not work. Defective door switch. Installed new switch and all is well. Putting new switch support definitely helps as the plastic tabs break easily removing the old switch. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
