SPEED QUEEN TR7 (TR7006WN / TR7006BN) Lock Clicking

Lid Lock Switch Assembly

The clicking sound is the solenoid attempting to drive the locking pin into the striker plate. When the internal sensor fails to communicate a successful engagement to the control board, the system cycles the power to the solenoid to attempt a re-lock. This failure is typically caused by high electrical resistance at the internal switch contacts or mechanical fatigue of the return spring.

Lid Striker

If the plastic striker attached to the lid is chipped, warped, or misaligned, the locking bolt will hit the face of the striker instead of entering the aperture. This physical obstruction prevents the lock from reaching the 'closed' position, causing the solenoid to bounce and click as it hits the obstruction and retracts.

Electronic Control Board

In rare instances, a failing relay on the main control board may chatter or provide insufficient current to the lid lock solenoid. This prevents the solenoid from fully overcoming the internal spring tension, leading to an incomplete throw of the locking bolt and subsequent clicking.
