What Does Error Code F23 Mean on a Maytag Dryer?
Exhaust thermistor short circuit.
F23 fires when the control board reads the exhaust thermistor circuit as shorted — resistance near zero ohms instead of the expected ~10kΩ at room temperature. Without a valid temperature signal the board can't regulate heat safely, so it halts the cycle. This differs from F22 (open thermistor, near-infinite resistance) in that F23 signals a dead short, most often the sensor itself or a harness wire chafed and grounding against the cabinet or blower housing.
