Error codeF91
ApplianceRange
F91 in plain terms
The oven has attempted to release its door more times than the control permits. Frigidaire counts F91 among the door lock issues, and the code belongs to current ovens controlled by an electronic oven control (EOC).
Do these first
Hit UNLOCK and answer whatever the display asks. It hands you a code that opens up the door and the panel.
If F91 sticks around, cut power to the unit for a stretch of up to 30 seconds, either at the plug or at the breaker.
According to the guide, most false codes disappear after that.
The technician’s sequence
Wiring that joins the EOC to the lock motor’s micro switch.
The motor door latch assembly.
Binding in the latch cam, the lock motor rod and the lock motor cam.
An open coil in the lock motor.
A lock motor that never stops running while its micro switch stays open: that earns a new lock motor assembly.
Last of all, the EOC.
Codes on the same theme
See F90 for a door that stayed unlocked too long, F94 for too many lock attempts and F92 for a door left open too long.

Model compatibility: Frigidaire 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.
Plain language
What this code means
F91 means the maximum oven door unlock attempts were exceeded, a door lock issue.
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.
