F8 — Door Latch Stuck

On Frigidaire microwaves, F8 indicates the door latch is stuck between open and closed — typically a defective latch motor/switch so the control cannot confirm a clean door state. It is not an EEPROM/memory fault. Check the door latch assembly and its switches.

  1. Unplug for 5 minutes; reset the clock and try a cycle.
  2. If F8 returns, the control board is failing — replace it.
  3. After replacement, set clock and any model-specific options per the tech sheet.
