How to Fix Frigidaire Oven Error Code F91

1. 1

   Let oven cool completely

   If self-clean just finished, the oven may still be above the latch-unlock threshold (typically 375°F / 190°C). Wait 1–2 hours and the door may unlock on its own.

2. 2

   Power cycle after cooling

   With oven cool, turn off circuit breaker for 10 minutes. On some models this resets the latch state machine and unlocks the door.

3. 3

   Manual latch release

   On most Frigidaire ranges, the latch has a manual release: remove the top rear panel and use a screwdriver to manually slide the latch to the unlocked position. Refer to the service manual for your model number.

   ⚠️ Range must be cool and unplugged before attempting manual latch release.
4. 4

   Replace the door latch assembly

   If the latch motor failed mid-cycle, replace the complete latch assembly.
