What this code means
The oven did not confirm normal door-lock movement or switch position. This often appears around self-clean operation.
Most likely causes
- The door is obstructed or misaligned
- The lock motor or switch has failed
- The lock linkage is jammed
- A harness or main-control fault is present
Safe checks for the owner
- Let the oven cool completely before attempting to open it.
- Do not force a locked door.
- Disconnect power for several minutes only after the oven is cool, then request service if it remains locked.
Estimated U.S. repair cost
$240–$480, depending on model, access, parts availability and local labor.
