Frigidaire oven error codes

16 codes that Frigidaire publishes for its ovens, each with what it means, the likely cause, what you can safely check and when to call a technician. Tap your code:

Switch off and unplug before checking. Anything electrical, anything to do with gas, and any water leak at the mains: call a technician. Codes that need one are marked Technician.

Read this first

Frigidaire, Electrolux’s North American brand, publishes two short code guides for its ranges and wall ovens: an oven error-code and alarms guide, and an error-code guide for its electric ranges. Their first step for any code is the same reset: unplug the unit for 30 seconds, or switch it off at the circuit breaker, then power it up again — Frigidaire says this clears most false error codes. Several codes below are given only a name (“Shorted Key Pad”, “Communication Error”): this page does not guess more than Frigidaire says. The same F codes do not mean the same thing on other makes, and AEG, Electrolux and Zanussi ovens sold in the UK use their own codes (see their page).

F10 Thermal runaway: oven too hot

What it means
The oven is detecting higher-than-normal temperatures. Frigidaire calls it a built-in safety alert that protects the appliance.
Likely cause
On a Stone-Baked Pizza oven, it can be the Pizza Shield in the wrong rack position. Otherwise not stated.
What you can safely check

Switch off and unplug before checking.

  • Turn the oven off and let it cool down before using it again.
  • Stone-Baked Pizza ovens: check the oven rack and Pizza Shield are in rack position 7 (some models differ — see the Use and Care Guide), reset the unit and start the pizza preheat again.
When to call a technician
If it keeps happening, call a technician: Frigidaire says to contact it for support.

What you can safely check

Switch off and unplug before checking.

A code that is not listed here

Frigidaire says to refer to the Use and Care Guide for your model for anything its guides do not cover. On an electric range, a dash (–) in the display means the cooktop is locked: press and hold OFF for 6 seconds to cancel the Lock feature.

We list only codes the source below states. If your code is not here, it may belong to a model the source does not cover: your model’s manual is the authority.
