Introduction
GE microwave door switches ensure that the appliance only operates when the door is properly closed. These switches are part of the microwave’s built-in safety system.
If a switch fails, the microwave may refuse to start or stop during use.
How GE Microwave Door Switches Work
When the microwave door closes, the door latch presses against switches located inside the microwave frame.
These switches signal to the microwave control system that the door is closed and the appliance can safely operate.
If the switch fails, the microwave may behave as if the door is still open.
