Customer Questions and Answers for Interlock (Door Switch) by Whirlpool

This interlock is the door safety switch assembly that keeps the appliance from running with the door open, restoring proper door sensing so the unit only operates when the door is fully closed. What it does

• Acts as the door safety switch to interrupt power or start signal when the door is open.
• Prevents the appliance from starting or running if the door won't latch or the switch fails.
• Common symptom: appliance does not start or stops immediately when the door is closed or opened.
• Useful when replacing a worn or damaged door latch/switch that causes intermittent operation.

• Disconnect power (unplug or switch off at the breaker) before servicing to avoid shock or injury.
• Access typically requires removing the appliance's front or control panel; keep track of fasteners and wire locations.
• Handle electrical connectors carefully; inspect wiring and connectors for damage before reconnecting.
• Test the switch with a multimeter.
