Oven door remains locked after cycle, or locks immediately on power‑up

Safety first: Disconnect power before attempting to release the lock manually. Internal surfaces may still be hot after pyrolytic cleaning.

• Allow cooling time: If the lock engaged during a pyrolytic (self‑clean) cycle, wait until the oven has fully cooled (up to 1–2 hours). The lock will not release until the safety thermostat detects a safe temperature.
• Manual release: Consult the user manual for the manual door release procedure. Many Brandt ovens have a mechanical release accessible through the top or front panel. Use a flat screwdriver to gently move the release lever.
• Inspect lock assembly: Remove the top cover and front panel to access the door lock. Check for broken plastic parts, misaligned latch, or disconnected rods. Test the lock motor/solenoid by applying appropriate voltage (only if you are qualified). Replace the complete door lock assembly if defective.
• Check lock microswitch: The control board monitors lock position via one or more microswitches. Test each switch for proper open/closed operation with a multimeter. Replace faulty switches or the entire lock module.
