GE Range Error Code F030

The F030 error code on a GE range indicates an open circuit condition in the oven temperature sensor, also known as an RTD (Resistance Temperature Detector). The RTD is a probe typically mounted inside the oven cavity that monitors temperature by varying its electrical resistance in direct proportion to heat. When the control board reads an open circuit instead of a valid resistance signal, it cannot determine the oven's actual temperature and will shut down the baking or broiling function to prevent unsafe operation.

The most common technical cause of this fault is a break in the wiring circuit between the RTD probe and the electronic control board. This can occur at the probe connector, along the wire harness routing, or at the control board terminal itself. A true open circuit means the electrical path has been completely interrupted, resulting in an infinite or unmeasurable resistance reading rather than the expected sensor value range the control board is designed to receive.

Diagnosing F030 begins with a thorough inspection of the probe circuit wiring for any open or short conditions. This includes checking the probe connector for corrosion or backed-out terminals, inspecting the harness for pinched or burnt sections, and testing the RTD probe itself for continuity. A properly functioning RTD will show a specific resistance value at room temperature. If wiring checks out and the probe tests open on a multimeter, the probe itself has likely failed and requires replacement.
