Kenmore Dryer Error Code E25

E25 on a Kenmore dryer means the control has detected an open circuit in the control thermistor. The control thermistor is a temperature sensor that should measure approximately 50K ohms. When the control board cannot detect a proper resistance reading from this sensor, it logs E25 and may stop the dryer from running normally.

A reset may temporarily clear the E25 display, but the code will return if the underlying fault is not corrected. Because E25 indicates a hardware problem with the thermistor circuit, clearing the code without repairing the sensor, wiring, or control board will not resolve the issue.

If only the control thermistor needs replacement, parts typically range from around $15 to $50 depending on the specific model. If the wiring harness requires repair, costs are usually minimal. A replacement electronic control board is the most expensive scenario, with parts generally ranging from $80 to $200 or more, plus labor if a technician performs the repair.

Many DIYers can resolve E25 by testing and replacing the control thermistor, which requires a multimeter and basic disassembly skills. Disconnect the thermistor wires and measure resistance. If the reading is outside 50K ohms plus or minus 10 percent, replace the thermistor. If the sensor tests good, check the wiring harness for breaks or loose connectors before considering a control board replacement.

Running the dryer with an active E25 code is not recommended. The control thermistor provides temperature feedback that the control board uses to manage the heating cycle. Without accurate temperature sensing, the dryer cannot regulate heat properly, which could result in overheating or inadequate drying performance.
