Samsung Oven DG64-00555A, Replaces 4444444444444444
A failed oven door locker is the most common cause of a Samsung oven that won’t start the self-clean cycle, displays a door lock error, or has a door that won’t latch and lock during high-temperature operation. In most Samsung ovens, the door locker is the motorized latch assembly that physically locks the oven door during self-clean cycles and high-heat operation — when the motor fails, the latch mechanism jams, or the switch inside the locker stops signalling correctly, the oven control board detects an unlocked door and refuses to start or complete the self-clean cycle. ⚡ Common failure point in Samsung ovens after repeated self-clean cycles and thermal stress on the latch motor. Part DG64-00555A is the genuine OEM replacement door locker that restores full door locking function and allows self-clean cycles to run normally with no modifications required.

The door locker motor and latch mechanism are among the most heat-stressed components in a Samsung oven — the extreme temperatures of a self-clean cycle (up to 900°F) accelerate wear on the locker motor and wiring every time it runs. Limiting self-clean cycles to once every few months and using manual cleaning between cycles significantly extends the life of the new locker and the surrounding wiring harness.
