Frigidaire Oven Heats Too Hot — What’s Happening
When a Frigidaire oven heats too hot, the control board is usually detecting higher-than-normal temperature and may display an F10 fault code as a safety alert. This is not a no-heat condition. The oven is genuinely overheating or running away past the setpoint, and the control is protecting the appliance by shutting down or warning you.
Frigidaire describes F10 as a runaway heating or overheating condition. The control sees oven temperature above the expected range and takes action. On some models with a Pizza feature, an incorrect Pizza Shield or rack position can also trigger F10-related overheating behavior during the Stone-Baked Pizza preheat cycle.
Most Likely Causes
- Failed oven temperature sensor (RTD probe) The most commonly cited cause in technician troubleshooting for F10 overheating on Frigidaire ovens is a sensor that has drifted out of calibration or failed internally.
- Stuck relay on the electronic control board A relay that remains closed can keep the heating element or burner energized when it should cycle off, causing runaway temperature.
- Wiring or harness problems between sensor and control board Opens, shorts, corrosion, or burned connectors can make the board read temperature incorrectly or intermittently, triggering an overtemp fault.
- Misplaced Pizza Shield or incorrect rack position On models with the Pizza feature, Frigidaire instructs that the Pizza Shield must be in rack position 7 during Stone-Baked Pizza preheat to avoid an F10 condition.
- Transient fault or control glitch A simple power reset can clear a one-time fault, but if the fault returns the underlying component issue remains and needs repair.
How to Diagnose and Fix
- Turn off power to the oven by unplugging it or switching off the breaker for at least 30 seconds, then restore power and retest to see if the fault clears.
- Verify the symptom by confirming the oven is actually overheating with an independent oven thermometer, not just showing an alarm from an incorrect feature setup or rack position.
- If your model has the Stone-Baked Pizza feature, confirm the Pizza Shield and rack are in position 7 as specified by Frigidaire before proceeding with part diagnosis.
- Disconnect power and access the oven temperature sensor (RTD probe), then use a multimeter to measure its resistance at room temperature.
- Compare the sensor reading to the expected value for your model. Many Frigidaire sensors should measure around 1100 ohms at room temperature, but this is model-dependent.
- Inspect the wiring harness and connectors between the sensor and the control board for opens, shorts, corrosion, burned pins, or continuity mismatch.
- Inspect the electronic control board for burnt spots, scorching, corrosion, or a relay that appears stuck or discolored.
- Replace the failed part (sensor, harness, or control board) and retest the oven for proper cycling and temperature control over a full preheat and bake cycle of 15 to 20 minutes.
Parts You Might Need
| Part | Notes |
|---|---|
| Oven temperature sensor (RTD probe) | Amazon | Model-specific. Many test around 1100 ohms at room temp. |
| Electronic oven control board (ERC or clock board) | Amazon | Contains relay circuitry. Replace if relay is stuck or board is scorched. |
| Wire harness or sensor wiring connector | Amazon | Only if harness is burned, corroded, or shows continuity faults. |

When to Call a Pro
If you are not comfortable working with 240-volt wiring, multimeter testing, or removing the oven control board, call a qualified appliance technician. Live voltage is present at the sensor harness and control board even when the oven is off, unless you disconnect power at the breaker or unplug the range. If the sensor tests good, the wiring is intact, and the fault persists, the control board relay is likely stuck and board-level diagnosis is best left to a pro. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
