What 350 means on a GE range

Error code 350 on a GE range indicates that the RTD1 sensor (Resistance Temperature Detector, the primary oven temperature sensor) has been detected as an open circuit. The control board continuously monitors the analog-to-digital converter (ADC) value from the RTD sensor. When that ADC count drops below the threshold expected for a valid sensor signal and stays there for a defined number of seconds, the control flags a raw fault and sets code 350. An open circuit in this context means the electrical path through the sensor or its wiring has been broken, preventing the board from receiving any meaningful temperature data.

RTD sensors work by changing their resistance in a predictable way as temperature changes. The control board reads this resistance through a voltage divider or similar circuit and converts it to a temperature value. When the circuit is open, resistance is effectively infinite, and the ADC reading collapses below the valid range. This is distinct from a short-circuit fault, where resistance would read near zero. A broken sensor element, a disconnected harness connector, or a damaged wire in the sensor circuit are all capable of producing this open-circuit condition.

Because the oven cannot confirm its actual temperature without a functioning RTD1 sensor, it will not operate safely in bake or broil modes while this fault is active. The first step is to press Cancel to reset the fault and attempt to clear it, but if the underlying issue persists, the code will return. Physical inspection of the sensor and its wiring harness is required to isolate whether the problem is in the sensor itself or in the circuit leading back to the control board.

Common causes of 350

  1. 01

    Failed RTD1 temperature sensor

    Part replacement

    The sensor element inside the oven cavity can burn out or break internally, creating an open circuit. This is the most common cause and can be confirmed by measuring the sensor's resistance across its two terminals with a multimeter. A healthy RTD sensor typically reads around 1080 ohms at room temperature. An open reading (infinite or OL) confirms sensor failure.

  2. 02

    Disconnected or loose harness connector

    Wiring / connection

    The wiring harness connector at the back of the RTD sensor or at the control board can work loose over time due to heat cycling and vibration. Visually inspect both ends of the sensor harness for connectors that have pulled apart or are seated at an angle.

  3. 03

    Damaged sensor wiring harness

    Part replacement

    The wires running from the RTD sensor through the oven cavity and back to the control board can develop breaks, burns, or chafing from contact with sharp metal edges or high heat. Inspect the full length of the harness for visible damage, melting, or pinched sections.

  4. 04

    Corroded or oxidized connector terminals

    Wiring / connection

    Terminal pins inside the sensor harness connectors can develop corrosion or carbon buildup that breaks the electrical contact without the connector appearing fully disconnected. Inspect the pins and sockets closely and clean them if contamination is present.

  5. 05

    Faulty oven control board

    Part replacement

    If the sensor and harness both test correctly and all connections are secure, the RTD input circuit on the control board itself may have failed. This is the least likely cause and should be considered only after the sensor and wiring have been fully ruled out.

Frequently asked questions about 350

What does 350 mean on a GE range?
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.
Can I reset error code 350 on my GE range and will it clear the fault?
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.
Is it safe to use my GE range while error code 350 is showing?
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.
How do I fix error code 350 on a GE range?
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.
How much does it cost to repair error code 350 on a GE range?
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.
