GE Range Error Code 350

Error code 350 on a GE range means the control board has detected an open circuit on the RTD1 sensor, which is the primary oven temperature sensor. The board monitors an ADC value from the sensor, and when that value drops below the valid threshold for several seconds, the fault is set. This prevents the oven from operating because it cannot confirm a safe and accurate temperature reading. The issue is typically caused by a failed sensor, a loose harness connector, or damaged wiring.

The oven's bake and broil functions should not be used while code 350 is active because the control board cannot read the oven temperature and cannot regulate heat safely. Surface burners on a gas range may still operate independently since they do not rely on the oven RTD sensor, but you should confirm this in your model's documentation. Avoid using the oven cavity until the sensor fault has been resolved.

If the RTD1 temperature sensor is the cause, replacement sensors typically cost between $20 and $60 for the part, and installation is a straightforward repair that many technicians or confident DIYers can complete in under an hour. If the wiring harness requires repair or replacement, expect part costs in the $30 to $80 range depending on the specific model. A control board replacement, if that is the root cause, is the most expensive scenario, with boards typically ranging from $150 to $350 or more for the part alone, plus labor if a technician is performing the work.

Yes, pressing the Cancel button will reset the fault and clear the code temporarily. However, if the underlying cause has not been corrected, the code will return as soon as the control board performs its next sensor check. A reset is a useful first step to confirm whether the fault is intermittent, but a persistent code 350 requires physical diagnosis of the sensor and its wiring.

Start by pressing Cancel to reset the code, then pull the range away from the wall and inspect the RTD1 sensor and its wiring harness for any visible damage, disconnected connectors, or burned wires. Use a multimeter to measure resistance across the sensor's two terminals. If the reading is open (OL or infinite), the sensor needs to be replaced. If the sensor measures correctly, trace the harness back toward the control board to check for breaks or corroded terminals.
