Error code F8 / F9
Appliance Range
Quick answer

F8 and F9 report lock motor switch problems on older Frigidaire EOC models.

Model compatibility: Frigidaire has used more than one control platform, so F8 / F9 may mean something different on another appliance or generation. Confirm this against your model documentation and record your full model number before acting.

Plain language

What this code means

Lock motor switches improperly positioned (out of sequence or shorted).

What F8 and F9 report

Older EOC models can show either code when the microprocessor finds the lock motor switches improperly positioned: out of sequence, or shorted.

Technician procedure

  1. Test the lock motor switches.
  2. If they are good and in proper sequence, replace the EOC.

For the owner

The fault sheet offers no owner-level fix, so book service rather than working on the door lock.
