Frigidaire Oven Error Code F3: How to Fix It

The Logic Verdict

Electrolux’s field trainer shows that F3 is usually the control board complaining because it never got a clean temperature/pressure reading after the last service event. The cure is not guesswork—it’s entering diagnostics with buttons 1 and 3, reading the stored codes, running the pump/fill/heater tests, wiping the fault history, and then launching the 13-minute calibration cycle so the sensor baseline is relearned.

What It Means

On these Gallery/Professional controls, F3 is the board flagging “temperature sensor feedback out of range.” The video proves the board stores the last three faults (his machine logged an i10 because the water was off) and it will keep shouting until you both clear the log and run the calibration so the pressure/temperature sensor matches the new fill profile.

Common Causes

• Water supply shut off or restricted, which instantly logs an i10/iF fill fault and cascades into F3 once the heater never sees water.
• A new or contaminated pressure/turbidity sensor installed without running the calibration cycle demonstrated in the video.
• Heater never energizing during the Heavy/Power Plus pre-wash—the trainer confirms you should see a 7–8 amp draw; anything less leaves the board thinking temperature is out of control.

Step-by-Step Fix

1. Wake the keypad and enter service mode. Restore power, open the door while the LEDs are lit, then hold buttons 1 and 3 for ~5 seconds until three indicators flash.
2. Read the stored codes. Tap button 1 to see the most recent fault (his flashed i10), then tap again to view the older two entries. Document what you find so you can verify the fix later.
3. Run the functional tests the trainer uses. Still in diagnostics, close the door and walk through test 5 (drain pump), test 6 (fill valve—listen for water), skip 7 unless the sump is full, test 8 (wash motor), test 9 (dispenser), and test 12 (vent fan). This confirms every load tied to the sensor is operating.
4. Clear the log and recalibrate. With the LEDs flashing, press button 2 once to light every segment; that wipes all three stored faults. Press button 3 next to launch the built-in 13-minute calibration cycle so the pressure/temperature sensor learns its new zero point.
5. Verify the heater the way he does in the video. Clamp an amp meter around the incoming hot lead, select the Heavy or Power Plus cycle, start the machine, and watch for the heater to pull roughly 7 amps right after the initial fill. If you never see that draw, chase the heater circuit before condemning the control.
