Error codeF050
ApplianceRange
F050 describes a lost signal from the door. On a freestanding Kenmore whose model number begins 790, what the oven relay board fails to read is the state of the door lock switches. On the Elite electric slide-ins (790.5256, 790.4131 and 790.4255) the relay control board is unable to see two things: the oven door switch and the oven door lock switch.
Steps, in the order the manual gives them
Take power away from the range.
Inspect the harness plugs running from the door lock switches to the relay control board. Elite owners have two harnesses to look at: the door lock and the door switch. A loose wire gets reconnected, and a damaged harness gets replaced.
A technician tests each switch using a multimeter. A dead door lock switch means the door lock assembly is swapped out; on the Elite, a dead door switch is replaced too.
Wiring and switches that all test good leave the relay control board as the part to change.
f045 is a cooling fan speed fault on the Elite models.

Plain language
What this code means
F050 means the relay board cannot detect the status of the door lock switches.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
