GE Oven Error Code F35

F35 means the control board has detected a resistance reading from the oven sensor circuit that falls outside the acceptable thresholds. The oven sensor is a probe inside the oven cavity that measures temperature by changing its electrical resistance. When the board cannot get a valid resistance reading, it triggers F35 and typically locks out normal oven operation.

No, you should not continue using the oven with F35 active. The error means the control board cannot reliably monitor oven temperature. Without accurate temperature sensing, the oven cannot regulate heat properly, which creates a risk of overheating. Most GE ovens will disable the bake and broil functions when F35 is present for this reason.

Yes. Unplug the oven, locate the sensor probe at the rear wall of the oven cavity, and disconnect it from its harness. Set a multimeter to measure resistance (ohms) and probe both terminals on the sensor. At room temperature, a good GE oven sensor should read close to 1080 ohms. A reading of infinite resistance indicates an open sensor, and a reading of zero or near-zero indicates a short. Either result confirms the sensor needs replacement.

Start by unplugging the oven and disconnecting the oven sensor harness connector at the control board. Use a multimeter to measure resistance across the sensor circuit terminals. A healthy GE oven sensor reads approximately 1080 ohms at room temperature. If the reading is far off, open, or shorted, replace the oven sensor. If the sensor tests good, inspect the harness for damage and check that the connector seats fully at the board. If both check out, the control board may need replacement.

If the oven temperature sensor is the cause, the sensor part typically costs between $20 and $60 depending on the model, and replacing it is a DIY-friendly repair that takes about 15 minutes with a screwdriver. If the wiring harness is damaged, a replacement harness runs $30 to $80. A new control board is the most expensive fix, often ranging from $150 to $350 for the part alone, plus labor if you hire a technician.
