Mabe Dryer Error Code E25

E25 on a Mabe dryer signals an open circuit detected in the control thermistor. The thermistor is a temperature-sensing component that should measure approximately 50K ohms of resistance. When the electronic control board cannot detect a valid signal from the thermistor, it displays E25 and stops the dryer to prevent unsafe operation.

A reset may temporarily clear the error code, but if the underlying fault persists, E25 will return as soon as the dryer attempts to operate. The thermistor open-circuit condition must be corrected by replacing the faulty component or repairing the wiring before the error will stay cleared.

If the thermistor has failed, the part itself is generally inexpensive, typically in the range of $10 to $40 depending on availability. If a wiring repair is needed, costs depend on the extent of the damage. A failed electronic control board is the most expensive outcome, with parts alone often ranging from $80 to $200 or more, plus labor if a technician performs the repair.

A knowledgeable DIYer can diagnose this error by disconnecting the thermistor wires and measuring resistance with a multimeter. If the reading is not within 50K ohms plus or minus 10 percent, replacing the thermistor is a straightforward repair. If the thermistor reads correctly, tracing and inspecting the wiring harness is also manageable, though board replacement requires more comfort working with appliance electronics.

You should not continue using the dryer with an active E25 error. The control thermistor provides the board with temperature data needed to prevent overheating. Operating the dryer without a functioning thermistor signal removes that safeguard and could create a fire hazard.
