Description

This set replaces the primary and secondary door interlock micro switches in the microwave's latch assembly. Restores reliable door sensing so cooking starts only when the door is fully closed and stops immediately when you open the door. What it does:

• Detects door open/closed position and signals the control to enable or disable operation
• Helps address symptoms such as: won't start unless pressing on the door, won't run, stops intermittently when the door is jostled, or continues running/light stays on when the door opens
• Restores proper safety interlock function and consistent start/stop behavior
• Intended for the latch/switch housing where the door hooks engage

What's included:

• Two micro switches: one primary and one secondary door interlock switch

Install notes:

• Unplug the microwave; the high-voltage capacitor can retain a dangerous charge—discharge it safely per the service procedure
• Access the latch/switch housing; note wire locations and transfer to the same terminals (COM/NO/NC) on the new switches
• Match the orientation of actuators and mounting to the originals to ensure proper engagement with the door latch
• After installation, test door operation and interlock function before full reassembly
