Frigidaire Oven F3 Code: Meaning & Fixes
- Meaning
- Communication error: the oven control has detected a fault in communication between its boards.
- Can I fix it?
- Sometimes, may need a pro
- Seen on
- Frigidaire electric ranges with electronic oven controls. Frigidaire groups F3 with F20 and F26.
Frigidaire’s current error code guide lists F3 with F20 and F26 as a communication error between the oven’s controls. Many repair sites call F3 an open oven sensor, but on current Frigidaire ranges that fault has its own codes, F30 and F31. Whichever it is, Frigidaire’s steps are the same: clear the code, retry, then remove power for 5 minutes.
Try this first
- Press Cancel (Clear/Off on some models) to clear the display and stop the beeping.
- Try Bake or Broil again.
- If F3 repeats, switch the range off at the breaker for 5 minutes, restore power and set the clock.
- If it comes back again, write down the code and call for service.

Record and call
Try Bake or Broil once more. If F3 comes back, write it down and call for service.
When to call a technician
If F3 returns after the 5-minute power reset, the control boards or their wiring need a technician. Frigidaire says to contact your installer if the range was installed within the last 30 days, and to schedule service with Frigidaire otherwise.
