How a Frigidaire range reports a fault
A Frigidaire range is diagnosed on two fronts. The Electronic Oven Control reports genuine “F” codes, so a stalled bake or a stuck self-clean shows a code. The cooktop is different — radiant elements and gas burners are mostly read by symptom. As a rule of thumb, F1x is a control failure, F3x an oven temperature-probe problem and F9x a door-latch motor problem.
The codes you will see
F10 is a runaway over-temperature condition — safety-critical: disconnect power and do not use the oven until it is repaired, as it points at a shorted sensor or a stuck relay. F30 means an open oven temperature probe (the RTD reads out of range) and F31 a shorted probe. F90 and F91 mean the self-clean door latch will not unlock in time or after repeated attempts. F1 and F11 are a failed control or a shorted keypad, while F12 and F13 point at the control-board memory. F40 is a cooktop lock-out, not a failure.
What to check, and when to call
For a one-off code after self-clean, let the oven cool fully and power-cycle at the breaker for five minutes. An F10 runaway means you stop using the oven immediately. A recurring sensor (F30, F31), control (F1, F11, F13) or door-latch (F90, F91) code needs an experienced, independent technician with the correct genuine OEM part; if you ever smell gas at a gas range, ventilate and shut off the supply first. See the range error codes page or the error codes library, then book range repair.
