Frigidaire Gallery Air Fry Oven F10 Error: Runaway... | appliancefaults.com

Technical Background:

The oven control board (MCU) monitors the oven temperature using a resistance temperature detector (RTD). The RTD's resistance changes with temperature. The MCU interprets this resistance and controls the heating elements via relays. An F10 error indicates that the MCU detects a temperature far exceeding the setpoint, indicating a potential fault in the sensor, wiring, or the control board itself. Voltage paths run from the MCU to the RTD and back.

Symptoms:

The homeowner observes that the oven temperature is rising uncontrollably, even when set to a low temperature or turned off. The F10 error code appears on the display. The oven may continue to heat even after the set time has expired.

Possible Causes:

Faulty oven temperature sensor (RTD).
Defective oven control board (ERC/MCU).
Shorted wiring harness to the temperature sensor.
Stuck or shorted oven relay on the control board.
Oven vent obstruction causing heat buildup.

Solution:

1

Disconnect power to the oven at the breaker panel (LOTO). Use a multimeter to confirm 0V AC at the oven receptacle.
2

Locate the oven temperature sensor (RTD) inside the oven cavity, usually at the top or back. Remove the sensor.
3

Use a multimeter to measure the resistance of the RTD. A typical reading at room temperature (70-75°F) should be around 1080-1090 ohms. Refer to the tech sheet for specific values.
4

Inspect the wiring harness connecting the RTD to the oven control board. Look for signs of damage, melting, or shorts. Repair or replace as needed.
5

Access the oven control board (ERC/MCU), usually located behind the control panel. Carefully examine the board for burned components or damaged traces.
6

Use a 1/4-inch nut driver to disconnect and then reconnect the RTD sensor wires to the board. This can sometimes reset the fault code.
7

If the RTD tests bad or the control board shows visible damage, replace the faulty component. Reassemble the oven and restore power.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. High voltage is present inside the oven. Use proper Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energization.

Prevention:

Periodically check the oven vents for obstructions. Avoid placing foil directly on the oven floor, as this can interfere with temperature sensing. Ensure the oven is properly calibrated per the manufacturer's instructions.

Expert Tip:

Some Frigidaire ovens have a service mode that allows you to calibrate the temperature sensor. Refer to the service manual for the specific procedure. Typically, it involves pressing a combination of buttons on the control panel to enter the service mode.

Frequently Asked Questions

•What is the typical resistance range for a good RTD sensor on this model at 350 degrees Fahrenheit?

Refer to the oven's technical sheet for the precise resistance value at 350°F. However, it will typically be in the range of 1400-1600 ohms.

•How do I access the oven's service mode to calibrate the temperature sensor?

Service mode access varies. Typically you press and hold Bake and Broil at the same time for 3-5 seconds. Look for a temperature offset adjustment.

•Where is the oven control board (ERC/MCU) located in this model?

The control board is typically located behind the control panel at the top of the oven. You may need to remove the top trim and/or the control panel fascia to access it. Be careful when removing the panel to avoid damaging any wiring.
