Customer Questions and Answers for Interlock Collar (Assembly) by Whirlpool

This interlock collar assembly centers and supports the door/lid interlock so the appliance can detect and secure the door during operation. Restores proper engagement of the latch for reliable start/lock behavior and safety sensing. What it does:

• Positions and stabilizes the interlock/lock mechanism so the door or lid can latch correctly.
• Helps the appliance register a closed/locked door so cycles can start and run.
• A worn, cracked, or broken collar can lead to failure-to-start, door not locking/unlocking, or intermittent door-latch problems.
• Works with the interlock/latch components to maintain safe operation of the door/lid assembly.

• Disconnect power before attempting any service; follow basic electrical safety.
• Replacement requires access to the door/lid latch—use appropriate hand tools and avoid forcing plastic tabs.
• Inspect the interlock and latch components for additional wear; replace damaged parts as needed.
• Refer to OEM instructions for model-specific removal and reassembly guidance.
