Frigidaire Range F12 Error Code

F12 is an electronic-control code in Frigidaire documentation. The public support article does not provide a homeowner component diagnosis, so keep checks limited to recording the code and one documented reset.

Applies to Frigidaire electric range or applicable cooktop with electronic controls

What the appliance detected

Detected condition

Frigidaire labels F12 as a Micro Identification condition.

What may contribute

Possible causes

  • The electronic control has reported the F12 Micro Identification condition.
  • Frigidaire’s public homeowner article does not identify a specific owner-serviceable component cause.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the exact code and model number

    • Photograph or write down F12 before clearing the display or disconnecting power.
    • Confirm the full model number and use the owner or Use & Care guide for that exact appliance before following any model-specific control procedure.

  2. Stop cooking and check only from the outside

    • Cancel oven and cooktop operation and allow hot surfaces to cool before doing anything else.
    • Do not remove panels, reach into control areas, touch heating components, or treat a cleared alarm as proof that the fault has been repaired.

  3. Use the documented power reset once

    • If there is no smoke, sparking, burning odor, wet-electrical hazard, or uncontrolled heating, Frigidaire says to disconnect power for up to 30 seconds, then restore it.
    • If the code remains or returns, stop resetting the appliance and arrange service or installer support as Frigidaire directs.

Actions not recommended

  • Do not remove control panels, rear panels, cooktop panels, or other service covers to chase the code.
  • Do not perform live-voltage, continuity, resistance, harness, sensor, relay, or control-board testing as a homeowner troubleshooting step.
  • Do not replace a keypad, sensor, probe, lock, wiring harness, or electronic control solely because the display showed this code.

When to stop and request service

  • Request qualified service if F12 remains or returns after the single manufacturer-documented reset.
  • For a newly installed unit, Frigidaire says to contact the installer when the problem cannot be resolved with the documented reset.
  • Leave the appliance off and seek urgent professional help for smoke, sparking, burning odor, uncontrolled heating, visible wiring damage, repeated breaker trips, or abnormal heat.
