How Do You Test A Microwave Door Switch?
To test a microwave door switch, first unplug the microwave from the power source. Then, remove the cover of the microwave to access the door switch. Use a multimeter to test for continuity across the switch terminals. With the door closed, the switch should have continuity. With the door open, there should be no continuity. If the switch fails these tests, it may need to be replaced. It is recommended to have a professional repair technician perform this task.
