Safety First: Disconnect power before accessing internal components.

Step 1 – Inspect thermistor wiring: Locate the outlet thermistor on the blower housing or exhaust duct. Check for pinched or rubbed-through wires touching metal or each other.
Step 2 – Test thermistor resistance: Disconnect the thermistor and measure resistance at room temperature. A very low reading (near 0 ohms) indicates a shorted thermistor that must be replaced.
Step 3 – Replace thermistor if shorted: Remove the mounting screw(s), install a new OEM Maytag thermistor, and reconnect the harness.
Step 4 – Inspect connector: Look for moisture, corrosion, or carbon tracking inside the connector. Clean or replace the connector if damaged.
Step 5 – Check control board: If a known-good thermistor tests correctly but F23 persists, the main control board's temperature sensing circuit may be shorted and require replacement.
Step 6 – Test dryer: Reassemble, restore power, and run a timed dry cycle to verify normal operation and temperature control.

Dryer will not start or shuts down; display shows F23 (outlet thermistor shorted).
