GE WB24X829 Microwave Secondary Door Interlock Switch

This OEM secondary interlock switch restores proper door safety detection, ensuring your microwave only operates when fully closed and properly latched.

If your microwave powers on and counts down but refuses to heat, a failed secondary door switch is a common cause. The GE WB24X829 works as part of the three-switch interlock system, confirming that the door hooks are fully engaged before allowing the control board to activate the heating circuits. Installation involves accessing the door latch assembly and replacing the switch while carefully transferring the existing wiring—always disconnect power before servicing.
