Quick answer
Kenmore F91 is an oven door unlock attempts code on 790 and 2014 ranges and a door lock failure on glass touch and Elite slide-in ranges.
Model compatibility
Kenmore reuses codes across series and model years, so F91 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Oven door lock failure
What to try on the glass touch and slide-in ranges
Start with a power reset: disconnect the range, count to 30 seconds, and reconnect. Activate the oven lockout feature or start a clean cycle and see if the door will lock. A door that refuses to open can be released with the cancel button.
No lock motor movement? Unplug the range and inspect where the harness meets the door lock assembly and the oven control board. Reattach loose wires and replace a harness with damage. After that the manual lists the door lock assembly, then the relay control board. The glass touch manual goes to the electronic oven control board after the lock assembly instead.
What a technician does on the 790 and 2014 ranges
Motor wiring and microswitch, cam binding, coil condition and a motor that runs without stopping are the points the manual names. The fix is a lock motor assembly or an oven door latch motor assembly, and the control board is the last item.
