Error codeF9
ApplianceWall Oven
If a self-cleaning wall oven from Kenmore or Kenmore Elite, model number beginning 790, shows F9, the door lock has failed.
Within the owner’s reach
Disconnect the wall oven from its outlet.
Go along the harness running from the door lock assembly to the electronic control board and tighten any slack connection.
A harness with damage is swapped for a new one.
Multimeter tests done by a technician
The door lock switch is tested twice. Arm pushed in: close to 0 ohms. Arm extended: OL.
Matching values in both positions condemn the whole door lock assembly.
Switch passes? Then the lock motor is measured, and infinite resistance there also means a new door lock assembly.
Other door codes
A self-clean latch that will not lock or unlock is F5/E1, and F5/E0 covers a door switch and latch switch at odds.
Door lock service in San Francisco
Because the lock tests need a meter, F9 belongs with a technician. Reach Kenmore wall oven repair for San Francisco and the Bay Area at (415) 825-6393, and pass along the 790 model number, the code and your notes on the lock wiring.
Model compatibility: Kenmore reuses codes across series and model years, so F9 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
