Error F3 on GE : Oven temperature sensor open circuit — sensor resistance is too high, indicating. Follow the troubleshooting steps below to diagnose and fix this range issue. ## What Error Code F3 Means on a GE JGS760SPSS Oven temperature sensor open circuit — sensor resistance is too high, indicating a broken wire or failed probe ## What This Error Means Error code F3 on your GE range indicates the oven temperature sensor has an open circuit. The sensor resistance is too high — the ERC reads a resistance significantly above the normal operating range, which it interprets as a broken sensor wire, a failed sensor element, or a disconnected sensor harness. The GE oven temperature sensor (RTD probe) reads approximately 1,080–1,100 ohms at room temperature. F3 is typically triggered when resistance rises above approximately 2,900 ohms or to OL (open loop). This can be caused by heat damage to the sensor after repeated high-temperature cycles, a cracked sensor probe, or a harness connector that has come loose. F3 is one of the most common GE oven error codes. The oven temperature sensor (sometimes called the RTD, thermostat probe, or oven sensor) is an inexpensive and accessible part — typically mounted with 2 screws on the upper-rear wall of the oven cavity, with a 2-wire harness running through the oven wall to the ERC. ## Quick Diagnostic Summary | Detail | Value | |--------|-------| | Error Code | F3 | | Severity | High | | Appliance | GE JGS760SPSS GE Gas Range | | User-Fixable | Yes | | Applicable Models | JB735SPSS, JGS760SPSS, JB645RKSS | ## Step-by-Step Troubleshooting | Step | Action | What To Do | Expected Result | |------|--------|------------|-----------------| | 1 | Confirm F3 with the oven powered on | Press Cancel/Off to clear the alarm. Attempt to set the oven to Bake at 350°F. If F3 appears immediately when the oven is set to bake (before it heats up), the sensor is failing at room temperature — a clear sign the sensor needs replacement. | F3 appears when setting the oven to bake, confirming the sensor failure is not temperature-dependent. | | 2 | Unplug and access the oven temperature sensor | Unplug the range. Open the oven door. The temperature sensor probe is on the upper-rear wall of the oven interior — look for a thin metal rod (approximately 3 inches long, 3/8 inch diameter) secured by 2 screws. Pull the range away from the wall slightly to allow the sensor to extend out as you pull it forward. | Sensor probe is visible on the upper-rear oven wall. Two mounting screws are accessible. | | 3 | Disconnect and test sensor resistance | Remove the 2 screws holding the sensor bracket. Pull the sensor forward until the wiring harness connector is accessible through the oven wall hole. Disconnect the connector. Test with a multimeter in resistance mode — expect 1,080–1,100 ohms at room temperature. Above 2,900 ohms or OL confirms F3. | Sensor reads above 2,900 ohms or OL at room temperature. F3 confirmed. Sensor requires replacement. | | 4 | Reseat harness connector if sensor tests OK | If the sensor tests within spec (1,080–1,100 ohms), inspect the harness connector for bent or corroded pins. Clean the contacts with an electronics contact cleaner. Reseat the connector firmly. Route the sensor back through the oven wall and reinstall the mounting screws. | Connector is reseated firmly. Sensor reinstalled with 2 screws. F3 clears after power restore if connector was the issue. | | 5 | Replace oven temperature sensor if F3 persists | Order the replacement oven temperature sensor (RTD) for your specific GE model. Part numbers include WB21X5243 and WB21T10007 — verify the correct part for your model on the GE parts website or AppliancePartsPros. Insert the new sensor through the oven wall, connect the harness, install the 2 mounting screws, restore power, and set the oven to bake to confirm F3 is cleared. | New RTD sensor installed. Oven heats to 350°F without F3. Temperature is stable throughout the bake cycle. | ## Frequently Asked Questions ### How long do GE oven temperature sensors last? GE oven RTD sensors typically last 5-10 years under normal use. Sensors degrade faster in ovens that are run at very high temperatures frequently (repeated self-clean cycles, frequent broiling) or in ovens with a history of spills that bake onto the sensor probe. If your range is over 5 years old and F3 appears, the sensor probe itself is the most likely culprit. ### Is replacing a GE oven temperature sensor a DIY repair? Yes. Replacing the oven RTD sensor is one of the most accessible DIY appliance repairs. It requires only a Phillips screwdriver and a multimeter. The sensor is mounted with 2 screws, the harness connector unplugs, and the new sensor installs in reverse order. Average DIY time is 15-20 minutes. ### F3 and F4 — what is the difference? F3 = sensor open circuit (resistance too high — above ~2,900 ohms or OL). The sensor wire is broken or the element has degraded to failure. F4 = sensor shorted (resistance too low — below ~950 ohms). The sensor’s internal element has shorted. Both require sensor replacement, but they indicate opposite failure modes. ### Can a loose wire harness cause F3? Yes. The 2-wire harness running from the sensor through the oven wall to the ERC board passes through a metal grommet hole in the oven back wall. Over time, the harness can chafe against the metal edge, causing a wire to break. If the sensor tests within spec when disconnected but F3 appears during oven operation, inspect the harness for chafing at the oven wall penetration point. --- Last Updated: March 2026 · GE GE Gas Range · Error Code F3 ### Is it safe to keep using my GE with error F3? If error F3 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 F3 on a GE ? Repair costs for error F3 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 F3 mean on a GE range? Error code F3 on GE range models indicates Oven temperature sensor open circuit — sensor resistance is too high, indicating a broken wire or fa. 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 F3?
