Customer Questions and Answers for Microwave Door Switch (Microswitch) by Ge

This microswitch senses the microwave door position and controls the safety interlock circuits. Replacing a worn switch restores proper start/stop behavior so the oven only runs when the door is fully closed.

• Detects door open/closed status to enable or disable cooking
• Part of the safety interlock system that stops operation if the door opens mid-cycle
• Replace if the switch fails a continuity check or shows heat or terminal damage

• Disconnect power before service; microwave capacitors can retain a dangerous charge
• Note wire positions and move them to the same terminals on the new switch
• Ensure the door latch cleanly actuates the switch; test operation before reassembly
