What Does Error Code F15 Mean on a Frigidaire Oven?

EOC / relay board communication loss — control fault.

F15 indicates a signal loss between the Electronic Oven Control (EOC) and the oven relay board, so the control can no longer command the heating relays. The range will not heat reliably until the link or a failed board is restored.

Frequently Asked Questions

Can I keep using my Frigidaire Oven when error F15 appears? +
It is not advisable. The oven may still power on, but running it while F15 is active can worsen the control-board fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes F15 on a Frigidaire Oven? +
Across reported Frigidaire oven repairs, the most frequent is loose/failed ribbon or wiring between EOC and relay board (40% of cases), relay board failure (30%), then eOC (control board) failure (25%). Check them in that order before replacing any parts.
F15 keeps coming back after a reset — what should I check next? +
A reset only clears the stored F15 fault; if it returns, the control-board problem is still present. Move on to the physical checks — power cycle, then reseat the EOC-to-relay wiring — 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 F15? +
A DIY repair typically runs $80–$280 in parts, versus $200–$500 for a professional service call, so handling it yourself saves around $120. Expect the work to take 1–3 hours.
