Frigidaire Dryer Error Code E25

E25 means the control board has detected an open circuit in the control NTC thermistor circuit. The control thermistor is a temperature sensor that should measure approximately 50K ohms at room temperature. When the circuit is open and no valid signal reaches the control board, the dryer displays E25 and stops operating normally. The fault can be in the thermistor itself or in the wiring connecting it to the control board.

No, you should not continue operating the dryer while E25 is active. The control thermistor provides temperature feedback that the control board uses to regulate drying cycles safely. Without a valid signal from this sensor, the dryer cannot properly monitor heat, which creates a potential overheating risk. Resolve the fault before resuming use.

Resetting the dryer by unplugging it for a few minutes may temporarily clear the E25 code, but the error will return as soon as the control board checks the thermistor circuit again if the underlying fault has not been repaired. A reset does not fix a failed thermistor, broken wire, or damaged connector. The only way to permanently clear E25 is to identify and correct the actual open-circuit fault in the thermistor circuit.

A knowledgeable DIYer can diagnose and sometimes fix E25 by using a multimeter to measure the control thermistor's resistance after disconnecting its wires. If the reading is not within 50K ohms plus or minus 10 percent, replacing the thermistor is a straightforward repair. If the thermistor tests correctly, tracing and repairing wiring issues requires more experience and the ability to safely access internal dryer components with the unit unplugged.

If only the control thermistor needs replacement, parts typically cost in the range of $15 to $50 depending on the specific model, making it one of the more affordable dryer repairs. If the fault turns out to be a wiring issue, cost depends on labor time to locate and repair the break. In the less common scenario where the electronic control board is at fault, board replacement can range from $100 to $250 or more for parts alone, plus any applicable labor costs.
