What Does Error Code F12 Mean on a Frigidaire Oven?

Electronic control identification / ROM fault.

    ⚠️ Unplug the range before accessing internal components.

Frequently Asked Questions

Can I keep using my Frigidaire Oven when error F12 appears? +
It is not advisable. The oven may still power on, but running it while F12 is active can worsen the control-board fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes F12 on a Frigidaire Oven? +
Across reported Frigidaire oven repairs, the most frequent is rOM/identification read error on the control (50% of cases), mismatched or wrong replacement control/UI board (25%), then ribbon/wiring fault between control and UI boards (15%). Check them in that order before replacing any parts.
F12 keeps coming back after a reset — what should I check next? +
A reset only clears the stored F12 fault; if it returns, the control-board problem is still present. Move on to the physical checks — power cycle, then verify board compatibility — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.
How much does it cost to fix Frigidaire Oven error F12? +
A DIY repair typically runs $100–$280 in parts, versus $200–$480 for a professional service call, so handling it yourself saves around $100. Expect the work to take 1–3 hours.
