Error codeF8 / F9
ApplianceRange
What the pair means
Either F8 or F9 may show on an older Frigidaire oven when the microprocessor decides the lock motor’s switches are in the wrong positions, whether through the wrong order or a short.
Technician procedure
Test the switches on the lock motor.
Once they prove good and correctly sequenced, fit a new EOC.
Advice to the owner
The fault code sheet offers no do-it-yourself fix, so book a visit and keep hands off the door lock.

Read F7 for the lock relay watchdog, F90 for an unlock that took too long, and F6 for a missing time base.
San Francisco service for Frigidaire ranges
A visit for F8 or F9 in San Francisco or the surrounding Bay Area starts with a call to (415) 319-6371. Have the exact code, the model number and earlier attempts ready. The Frigidaire range repair page has the rest.
Model compatibility: Frigidaire reuses codes across series and model years, so F8 / F9 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
F8 and F9 mean the lock motor switches are improperly positioned, out of sequence or shorted.
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.
