Safety First: Unplug the dryer and shut off the gas supply (if applicable) before servicing.

Step 1 – Locate inlet thermistor: On models equipped with an inlet thermistor, it is typically mounted near the air inlet or on the front bulkhead.
Step 2 – Inspect wiring and connector: Ensure the thermistor connector is fully seated and that wires are not pinched or broken.
Step 3 – Measure resistance: Disconnect the thermistor and measure its resistance at room temperature. Compare the reading to the specification in the tech sheet. Replace the thermistor if the reading is open, shorted, or significantly out of range.
Step 4 – Replace faulty thermistor: Remove the mounting screw(s), install the new OEM Maytag inlet thermistor, and reconnect the wiring.
Step 5 – Control board evaluation: If the thermistor and wiring are confirmed to be good but F24 persists, the main control board may not be reading the sensor correctly and may need replacement.
Step 6 – Test cycle: Reassemble the dryer, restore power, and run a sensor dry cycle to confirm proper operation.

Dryer displays F24 and may not heat properly.
