GE Dryer Error Code E25

E25 on a GE dryer indicates an open circuit in the control NTC thermistor circuit. This means the electronic control board is not receiving any resistance signal from the control thermistor, which is responsible for monitoring temperature. The fault can originate in the thermistor itself, the connecting wiring, or in some cases the control board.

Running the dryer while E25 is active is not recommended. The control thermistor provides temperature data that the electronic control uses to regulate the heating system. Without a valid thermistor signal, the control cannot monitor temperatures accurately, which could result in overheating or other unsafe operating conditions.

Repair costs depend on which component has failed. A replacement control thermistor is generally an inexpensive part, typically in the range of $15 to $40. If the electronic control board is at fault, that part typically costs between $100 and $250 or more depending on the model. Adding professional labor can bring total repair costs to the $150 to $350 range for a board replacement.

A knowledgeable DIYer can diagnose and often fix E25 with a basic multimeter. The process involves disconnecting the control thermistor and testing its resistance. If the reading is outside 45K to 55K ohms, replacing the thermistor is straightforward. If the thermistor tests good, tracing the wiring harness for breaks or loose connectors is the next step, which also requires no special tools.

A power reset may temporarily clear the E25 code, but if the underlying fault in the thermistor or wiring still exists, the error will return once the dryer attempts to operate. The fault must be corrected at the component level to permanently clear the code. Resetting without repairing does not resolve the root cause.
