Oven shows E021, often after a self-clean (pyrolytic) cycle, and will not heat

Safety: Ensure the oven is cool and power is disconnected before working on the lock mechanism.

• Check door status: Verify whether the door is physically locked. If locked, do not force it open.
• Power reset: Turn off the breaker for 15 minutes, then restore power to see if the lock releases automatically.
• Manual release: Consult the user manual for a manual door lock release procedure (often accessible through a small opening or by removing the top panel).
• Inspect lock assembly: With the top/front panel removed, inspect the lock motor, linkage, and microswitches for heat damage or misalignment.
• Switch test: Test the lock position switches with a multimeter to ensure they change state when the lock moves.

Recommendation: If the lock is heat-damaged or the switches are unreliable, replace the complete lock assembly. Persistent E021 after replacement may indicate a control board issue.
