Error F2 on GE : Oven overtemperature — oven cavity temperature exceeded the safe operating thres. Follow the troubleshooting steps below to diagnose and fix this range issue. ## What Error Code F2 Means on a GE JB735SPSS Oven overtemperature — oven cavity temperature exceeded the safe operating threshold ## What This Error Means Error code F2 on your GE range means the oven cavity temperature has exceeded the safe operating limit monitored by the ERC. During normal baking, GE ranges cap oven temperature at approximately 590°F (310°C). During self-clean, the limit is set higher (around 950°F / 510°C). When the oven sensor reports a temperature above these limits, F2 is triggered, the oven shuts off, and the alarm sounds. The most common causes: a stuck relay on the ERC board (keeps the bake or broil element energized continuously), a faulty oven temperature sensor reporting values above the actual temperature, or the oven being used at or near the self-clean temperature with the door seal degraded. The GE oven temperature sensor (RTD probe) should measure approximately 1,080–1,100 ohms at room temperature (~70°F). F2 can also be triggered if the sensor reads incorrectly high. A sensor reading below 500 ohms or above 3,000 ohms at room temperature indicates failure. ## Quick Diagnostic Summary | Detail | Value | |--------|-------| | Error Code | F2 | | Severity | High | | Appliance | GE JB735SPSS GE Electric Range | | User-Fixable | Yes | | Applicable Models | JB735SPSS, JGS760SPSS, JB645RKSS | ## Step-by-Step Troubleshooting | Step | Action | What To Do | Expected Result | |------|--------|------------|-----------------| | 1 | Press Cancel/Off and allow full cool-down | Press Cancel/Off immediately. Leave the oven door closed and allow the oven to cool for at least 30 minutes. Do not open the door — opening the door lets cold air in rapidly and may cause thermal shock to the oven components. F2 may clear automatically once the oven cools below the safety threshold. | Alarm stops and F2 clears once the oven cools below the overtemperature threshold. | | 2 | Test oven temperature sensor resistance | Unplug the range. Open the oven and locate the temperature sensor probe on the upper-rear oven wall (a thin metal rod about 3 inches long, two screws). Disconnect the sensor wires. Test resistance with a multimeter — expect 1,080–1,100 ohms at room temperature. A significantly higher reading suggests the sensor is drifting toward an F3 (open) condition. A lower reading suggests a short toward F4. | Sensor reads 1,080–1,100 ohms at room temperature (within spec). Values significantly above or below this range indicate sensor failure. | | 3 | Test for stuck bake relay (electric ranges) | Restore power. Set oven to Bake at 350°F. After preheating, observe the bake element — it should cycle on and off to maintain temperature. If the bake element stays on continuously without cycling, the ERC relay is stuck closed. The ERC must be replaced. | Bake element cycles on and off after reaching temperature. If it stays on continuously, the relay is stuck. | | 4 | Inspect oven door seal | Open the oven door fully. Inspect the door gasket (the fibrous rope or silicone seal around the oven opening) for tears, compressed areas, or sections that are no longer making contact with the oven frame. A degraded seal allows heat to escape around the door, but it also allows the oven to overshoot temperature during self-clean cycles. | Oven door gasket is intact and makes full contact around the oven perimeter. No tears or severely compressed sections. | | 5 | Replace temperature sensor if outside spec | Order the replacement oven temperature sensor for your GE model (RTD probe). Disconnect the old sensor (2 screws + wiring), install the new sensor, reconnect the wires, and restore power. Run an oven calibration test (Bake at 350°F for 30 minutes) to confirm F2 does not return. | New temperature sensor installed. Oven bakes at 350°F for 30 minutes without F2. Temperature is stable. | ## Frequently Asked Questions ### Can a dirty oven cause F2? Heavy grease deposits on the oven walls and floor can contribute to F2 during self-clean cycles, because burning grease adds additional heat to the oven cavity. Always wipe large spills from the oven before running self-clean. Never line the oven floor with foil — foil traps heat and can cause temperatures to rise beyond normal limits. ### F2 only appears during self-clean — is the range defective? If F2 appears only during self-clean and not during normal baking, the oven may be reaching temperatures slightly above the self-clean safety threshold due to a degraded door seal or a slightly inaccurate temperature sensor. Check the door seal and consider reducing the self-clean frequency to once every 3-4 months. ### What is the GE oven temperature sensor resistance specification? The GE oven temperature sensor (RTD probe) reads approximately 1,080–1,100 ohms at room temperature (~70°F / 21°C). Resistance increases as temperature rises: at 350°F it reads approximately 1,250 ohms; at 500°F approximately 1,400 ohms. F2 is triggered when the sensor reports a value indicating above-safety temperatures. F3 is triggered when resistance is too high (open sensor). F4 when resistance is too low (shorted sensor). ### Can F2 damage the range? A single F2 event that the ERC catches quickly typically does not cause permanent damage. Repeated F2 events — particularly during self-clean — can damage the door hinges, door gasket, and oven cavity enamel from repeated extreme heat cycling. Address the root cause of F2 before running additional self-clean cycles. --- Last Updated: March 2026 · GE GE Electric Range · Error Code F2 ### Is it safe to keep using my GE with error F2? If error F2 does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the range with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error F2 on a GE ? Repair costs for error F2 on the GE range depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a GE-authorized service provider for an accurate estimate based on your specific situation. ### What does error code F2 mean on a GE range? Error code F2 on GE range models indicates Oven overtemperature — oven cavity temperature exceeded the safe operating threshold. This error is detected by the appliance’s internal diagnostic system and displayed to alert the user that attention is needed. Refer to the troubleshooting steps above for guidance on resolving this issue. ### Is it safe to keep using my GE with error F2?
