Maytag Dryer Error Code F25 — Inlet Thermistor Failure
What this means
The F25 error code indicates the dryer's inlet thermistor is not providing a valid temperature reading to the control board. The inlet thermistor monitors the temperature of air entering the drum. A failed sensor can cause the dryer to not heat or to overheat, both of which affect drying performance.
Alternate codes: F-25
Step-by-step fix
4 stepsLocate the inlet thermistor
Unplug the dryer and remove the access panel. The inlet thermistor is typically located near the heater housing or at the air inlet to the drum.
The inlet thermistor is a different sensor than the exhaust thermistor — check your tech sheet.
Test the thermistor
Disconnect the thermistor wires and measure resistance with a multimeter. At room temperature, it should read approximately 10,000 ohms.
An open circuit (infinite ohms) or short (0 ohms) confirms the sensor is bad.
Check wiring connections
Inspect the wire harness from the thermistor to the control board for damage, loose connections, or corrosion.
A broken wire can cause the same symptoms as a faulty thermistor.
Replace the inlet thermistor
Remove the mounting screw, disconnect the old thermistor, and install the new one in the same location.
Double-check that you are replacing the inlet sensor, not the exhaust sensor.
When to call a professional
If replacing the thermistor does not clear the error, the control board may need replacement, which a technician should diagnose.
