None Oven: error code when overheating
What is this symptom?
Experiencing an error code on your oven during overheating? This often indicates a thermal runaway condition, where the oven's temperature exceeds safe limits, resulting in beeping alerts and possible shutdown. Common error codes include F2 and F10, signaling potential issues with the temperature sensor or control board. Immediate attention is required to prevent further damage.
Important Tips for None Models
- Official support for Range error code F2 states the likely issue is with the Oven Temperature Sensor, Control, or associated wiring, and recommends a 1-minute breaker reset and monitoring for recurrence.
- Official support defines F10 as 'Thermal Runaway' and recommends a short power reset; if unresolved, service is required.
- GE ovens commonly use F2/F20 to indicate an overheat/runaway heat condition; community/repair references thresholds and commonly point to the sensor or control board.
Possible Causes
Failed or drifting oven temperature sensor / RTD probe (reads wrong temperature, causing control to think oven is overheating or actually overheat due to misregulation)
How to Identify: Error occurs after oven heats up; temperature may overshoot setpoint or fluctuate; code returns after reset. Sensor resistance testing may show out-of-range values (commonly ~1080 ohms at room temperature for many RTD designs, but verify for your model.
Part: Oven temperature sensor (RTD probe) and sensor circuit
Stuck relay on the electronic oven control (EOC) / control board (heating element stays powered too long, causing true runaway heat)
How to Identify: Oven continues heating beyond the set temperature; may keep heating even after you cancel/turn off until breaker is switched off; visible burning smell; error reappears after resets; sometimes element stays on continuously.
Part: Electronic oven control board (EOC), bake/broil relays
Wiring harness damage, loose connectors, or short/open in the sensor circuit (control receives incorrect readings and triggers over-temp/thermal runaway code)
How to Identify: Intermittent codes (especially when the oven is hot and wires expand; sensor tests good at the probe but readings are incorrect at the control board connector; visible melted insulation, corrosion, or loose terminals.
Part: Sensor wiring harness, control board connector pins
Cooling fan / ventilation problem leading to control area overheating (especially on wall ovens and convection models) which can trigger over-temperature protection
How to Identify: Error appears during long high-temperature bakes or self-clean; cabinet area feels excessively hot; cooling fan does not run when expected; problem improves with better ventilation or after fan replacement.
Part: Cooling fan, airflow pathways, vents
Door gasket leak or door not sealing properly causing temperature regulation instability (can lead to overshoot and error in some models during high-heat cycles)
How to Identify: Visible gasket damage; heat escaping around door; uneven baking; error tends to appear during self-clean or extended high-temperature use; temperature swings noticeable.
Part: Door gasket / seal, door hinges/latch alignment
DIY Solutions
Immediate safety shutdown + reset (clear code and prevent further overheating)
- If the oven is still heating uncontrollably or smells extremely hot, press CANCEL/OFF.
- If heat does not stop, switch OFF the circuit breaker to the oven/range immediately.
- Allow the oven to cool completely.
- Restore power and observe whether the code returns within 1 minute (many brands recommend a brief power reset to clear transient faults).
Inspect oven vents and confirm cooling fan operation (reduce control-area overheating)
- Ensure vent openings are not blocked by foil, cookware, or debris.
- Run the oven and listen for the cooling fan (many models run the fan during heating and/or after shutdown).
- If the fan never runs and the oven repeatedly throws overheating codes during longer cycles, stop using the oven and schedule service.
Test and replace the oven temperature sensor (RTD probe) if out of spec
- Turn OFF power at the circuit breaker before disassembly.
- Locate the oven temperature sensor (typically a metal probe mounted to the back wall inside the oven cavity).
- Remove the mounting screws and carefully pull the sensor forward to access the connector.
- Disconnect the sensor and measure resistance with a multimeter (many RTD sensors read around ~1080 ohms at room temperature, but confirm the correct spec for your model if available).
- If resistance is out of range or changes erratically when gently moving the wire/connector, replace the sensor with the correct part for your model.
- Restore power and test oven operation for at least one full heat cycle.
Check sensor wiring harness and connector integrity (heat-damage inspection)
- Turn OFF power at the circuit breaker.
- Access the rear panel (range) or service panel (wall oven) depending on your installation.
- Inspect wiring between the sensor and control board for melted insulation, pinched wires, corrosion, or loose connectors.
- With the sensor disconnected, perform continuity checks from the sensor connector to the control board connector (no shorts to chassis).
- Reseat connectors firmly; replace damaged wiring/terminals or schedule service if damage is extensive.

When to Call a Professional
Preventive Maintenance
-
Keep oven vents clear and avoid covering vent openings with foil or cookware: Control-area overheating that can contribute to over-temperature faults
Frequency: Every use -
Inspect the door gasket for tears, gaps, or looseness and replace if damaged: Temperature instability and heat leakage that can worsen overheating-related errors during high-heat cycles
Frequency: Every 6-12 months -
Use self-clean sparingly and ensure proper ventilation in the kitchen: High-heat stress on sensors, wiring, and control boards associated with thermal runaway errors
Frequency: As needed (avoid frequent use)
