Electrolux Oven Error F90

DIY Fix Basic Reset and Verification

1. Disconnect oven power at the mains or circuit breaker for ~30 seconds to reset controls.
2. Reconnect power and observe if F90 clears.
3. Ensure oven door is fully closed and unobstructed before retrying to operate the oven.

Technician Only Inspect/Repair Door Lock System

1. Disconnect power and remove necessary panels to access door lock mechanism.
2. Inspect door lock motor and linkage for damage, binding, or heat distortion—especially if from a self‑clean cycle.
3. Test lock motor and switch continuity with multimeter; replace components that fail testing.
4. Check harness and connectors between lock assembly and oven control board for continuity and secure connections.
5. Verify control board outputs correct signals to lock assembly; if lock and wiring are good but F90 persists, consider board diagnosis/replacement.

Parts needed: door lock motor/assembly, door lock switch, wiring harness, electronic oven control board (if required)
