Maytag Dryer Error Code F-24

F-24 on a Maytag electric dryer means the control board has detected an open circuit in the inlet thermistor, the temperature sensor located at the dryer's air intake. This code only appears during diagnostic test mode and does not indicate a catastrophic failure, but it does mean the sensor circuit is broken. The cause can be a failed thermistor, a loose wire connection, or damaged wiring between the sensor and the control board.

Since F-24 only appears in diagnostic test mode, a power reset may clear it from the display, but it will return the next time a diagnostic cycle is run if the underlying fault has not been repaired. The open circuit in the thermistor wiring or the failed sensor must be corrected to resolve the code permanently. Resetting without repair does not restore proper temperature sensing function.

If the fix is simply reseating a loose wire connector, the repair costs nothing beyond your time. Replacing a failed inlet thermistor typically costs between $15 and $40 for the part, plus labor if a technician performs the work. If the machine control board itself has damaged terminals or is faulty, repair costs can range from $100 to $300 or more depending on the board and labor rates in your area.

Start by checking all wire connections at the inlet thermistor and the machine control board for loose or corroded terminals, as this is the first step in the TEST #4a diagnostic procedure. If all connections appear secure, use a multimeter to test the thermistor's resistance to determine if the component itself has failed. A broken wire in the harness between the thermistor and control board is also possible and can be found with a continuity test. Replace any failed component once identified.

The F-24 code only appears in diagnostic mode, so normal drying cycles may still initiate. However, an open inlet thermistor circuit means the control board cannot accurately monitor incoming air temperature, which can affect how the dryer regulates heat. Running the dryer without a functioning temperature sensor is not recommended for extended periods, as temperature control may be unreliable.
