GE Oven Error Code Upper Thermal Sensor SHORTED

This error means the control board has detected a short circuit in the upper oven temperature sensor circuit. The sensor or its wiring is showing abnormally low resistance, which signals a fault condition to the control board. The oven will not heat normally while this code is active. The fault originates at the sensor, the wiring harness, or the CN9 connector on the power board.

You should not attempt to use the oven while this error is active. A shorted thermal sensor means the control board cannot accurately monitor upper oven temperature, which removes a key safety protection. Continued use could result in uncontrolled heating or component damage.

If only the upper thermal sensor needs replacement, parts typically range from $20 to $60 depending on the model, with labor adding $75 to $150 if a technician performs the repair. If the wiring harness or power board is also involved, total repair costs can range from $150 to $350 or more. Getting a diagnostic estimate before committing to parts replacement is advisable.

A knowledgeable DIYer can perform some of the diagnostics, including visually inspecting the sensor wiring for damage and checking the CN9 connector for obvious faults. Replacing the upper thermal sensor is also a relatively straightforward repair if the sensor is confirmed faulty. However, working near oven wiring requires the appliance to be fully unplugged, and replacing the power board should be done by someone comfortable with appliance electronics.

Resetting the oven by cutting power at the breaker may temporarily clear the display, but the error code will return as soon as the control board re-checks the sensor circuit. The underlying short circuit in the sensor or wiring must be diagnosed and repaired to permanently resolve the fault.
