F9 displayed; oven door may not lock/unlock properly during self-clean (if equipped) or oven will not start.

Safety First: Disconnect power before working on the door lock mechanism. Beware of sharp metal edges around the oven frame.

Step-by-step:

• Check door movement: With power off, open and close the oven door. Ensure it closes fully and the latch engages smoothly. Look for bent latch or misaligned door.
• Access lock assembly: Remove the top panel or rear panel (depending on Premier model) to access the door lock motor and latch assembly.
• Inspect linkage: Check for bent rods, broken plastic pieces, or obstructions preventing the lock from moving. Clear obstructions and straighten minor bends.
• Test lock motor and switches: With a meter, test continuity of the lock motor and associated lock/unlock switches according to the wiring diagram. Replace the door lock motor assembly if open or mechanically seized.
• Check wiring: Inspect harness from lock assembly to EOC for damage or loose connectors. Repair as needed.
• Control board: If the lock assembly and wiring are good but F9 persists, the EOC lock driver circuit may be faulty. Replace the Electronic Oven Control (EOC).
