Introduction
The microwave door switch is usually located behind the front panel of the microwave near the door latch. Most microwaves contain two or three switches mounted in a small plastic bracket.
These switches confirm that the microwave door is securely closed before the appliance begins operating.
How the Door Switch Is Positioned
When the microwave door closes, the door latch hooks enter the microwave frame and press against the door switches.
This activates the switches and signals to the microwave control system that it is safe to operate the appliance.
If the switches do not activate correctly, the microwave will usually refuse to start.
