GE Dryer Error Code 15

Error code 15 on a GE dryer means the control board has detected a Water Temp Sensor Invalid condition. This indicates the thermistor, which is the component that monitors dryer temperature, is either disconnected, not present, or has failed. The board cannot read a valid resistance value from the sensor circuit, so it flags the fault to prevent unsafe operation.

It is not recommended to operate the dryer while error code 15 is active. The thermistor is the component that allows the control board to regulate heating cycles accurately. Running the dryer without valid temperature feedback increases the risk of overheating, which can damage clothing or create a fire hazard.

Repair costs depend on which component is at fault. A replacement thermistor typically costs in the range of $15 to $50 for the part alone. If the control board needs to be replaced, parts can range from $100 to $300 or more depending on the model. Adding professional labor will increase the total cost, generally ranging from $100 to $200 for a service call and repair time.

Some causes of error code 15 are DIY-friendly, such as reseating a loose connector at J701 on the control board or inspecting the wiring harness for visible damage. If the thermistor itself has failed, replacing it is a moderate-difficulty repair that requires basic hand tools and a multimeter to confirm the diagnosis. Control board replacement is more complex and may be better left to a technician.

A power reset may temporarily clear the error code display, but if the thermistor or its wiring circuit remains faulty, the code will return as soon as the dryer runs a cycle. A reset alone does not address the underlying hardware problem. The thermistor circuit must be tested and the root cause corrected for the error to stay cleared.
