Possible Causes

Failed door lock motor, Faulty lock switch, Wiring issue between lock and control, EOC lock driver failure

How to Fix / Troubleshooting

Safety first: Disconnect power and allow the oven to cool.

  • Check door latch movement: With the top or rear panel removed, manually move the latch to ensure it is not mechanically jammed.
  • Test motor and switch: Use a multimeter to check motor winding resistance and switch continuity. Replace the lock assembly if readings are out of spec.
  • Inspect wiring: Verify the harness from the lock to the control is intact and connectors are tight.
  • Replace EOC if needed: If the lock assembly is good but F90 persists, the control board may not be driving the motor correctly.
