Oven display shows F9, oven door may not lock or unlock during pyrolytic self-clean (if equipped).

Safety first: Disconnect power at the breaker. If the door is locked with racks or items inside, do not force it open; damage to the door or frame can occur.

• Access lock assembly: Remove the top panel or front trim to reach the door lock motor and latch assembly, typically located at the top of the oven cavity.
• Inspect for mechanical jams: Check the lock arm and latch for bent metal, grease buildup, or foreign objects. Clean and lubricate lightly with high-temperature-safe lubricant if necessary.
• Test lock motor: With the connector unplugged, measure resistance across the lock motor terminals. An open circuit indicates a failed motor that must be replaced.
• Check lock switch: Many Asko ovens use a microswitch to confirm locked/unlocked position. Test continuity while manually moving the latch. Replace the switch if it does not change state reliably.
• Wiring inspection: Inspect the harness from the lock assembly to the main control board for breaks or heat damage. Repair or replace as needed.
• Manual release: If the door is stuck locked, consult the service manual for the manual release lever location (often accessible from the top). Use only gentle force to avoid bending components.
