Display shows F9, oven door will not lock or unlock during self-clean, or door remains locked after cycle.

Safety first: Disconnect power at the breaker. The door lock mechanism can move unexpectedly when power is restored.

• Allow oven to cool: If just after self-clean, wait until the oven is completely cool; the lock will not release while hot.
• Check for mechanical jam:
  • Inspect the door latch area for bent metal, grease buildup, or foreign objects.
  • Gently move the latch with a screwdriver (with power off) to see if it is stuck.
• Access lock assembly:
  • Remove the rear panel or top panel (depending on model) to access the door lock motor assembly.
  • Inspect the lock motor, linkage, and switches for damage or disconnection.
• Test lock motor and switches:
  • With a multimeter, check continuity of the lock motor coil and door lock switches according to the tech sheet.
  • Replace the door lock assembly if the motor is open or switches do not change state when the latch is moved.
• Wiring and control: If the lock assembly tests good, inspect wiring to the control board. If wiring is intact, the electronic control may be defective and require replacement.
