GE Range Error Code F30

F30 indicates an open condition in the RTD temperature sensor probe circuit. The oven's control board has detected that it cannot receive a valid resistance signal from the temperature sensor, either because the sensor itself has failed or because there is a break in the wiring connecting it to the board. The oven shuts down to prevent uncontrolled heating. In some cases, the board may briefly show F10 before settling on F30.

The oven portion of the range should not be used while F30 is active. Without a functioning temperature sensor, the control board has no way to regulate oven temperature accurately, which creates a risk of overheating. Surface burners on a gas or electric range may still function, but the oven should remain off until the sensor or wiring fault is diagnosed and corrected.

If only the RTD sensor probe needs replacement, parts typically range from around $20 to $60 depending on the model, and the repair is manageable for a confident DIYer. If the EOC-Display Board is the cause, board replacement parts can range from roughly $100 to $300 or more, and professional labor will add to that cost. A service call for diagnosis and repair by a technician generally runs between $150 and $400 total depending on the part needed and your location.

You can attempt to clear the code by turning off power to the range at the circuit breaker, waiting a few minutes, and restoring power. However, if the underlying open circuit in the RTD sensor or its wiring has not been repaired, the F30 code will return as soon as you attempt to use the oven again. Resetting is useful for testing after a repair, not as a fix on its own.

Start by inspecting the wiring harness from the RTD sensor probe to the EOC board for any visible damage, loose connectors, or burned terminals. Next, measure the resistance of the RTD probe with an ohmmeter at room temperature and compare it to the probe resistance chart for your model. If the resistance is out of range or shows no continuity, replace the RTD sensor probe. If the probe and wiring check out correctly but the error persists after cooling and restarting the oven, the EOC-Display Board will need to be replaced.
