Error codeF090
ApplianceRange
F090 reports a door lock problem: the relay control board never sees the lock motor working. Two entries exist, one for Kenmore 790 freestanding ranges and one for Kenmore Elite electric slide-ins, 790.5256, 790.4131 and 790.4255.
Power reset
Take power off the range for 30 seconds, then put it back. Next, try to get the door to lock again by starting either Oven Lockout or a Clean cycle.
If the motor stays silent
Cut power again.
Inspect the wiring that runs from the lock assembly to the relay control board. Loose wires are reconnected; a harness with damage is replaced.
If the wiring is in good shape, the lock assembly itself is the part to replace.
Should F090 remain, the relay control board is the last replacement.
f050: the board cannot read the door lock switches.
