Possible Causes

Safety First: Disconnect power before servicing.

Step 1 – Inspect thermistor connector: Ensure the connector is fully seated on the thermistor terminals.
Step 2 – Test thermistor: Disconnect and measure resistance at room temperature. Infinite resistance indicates an open thermistor that must be replaced.
Step 3 – Replace thermistor: Remove mounting screw(s), install a new OEM thermistor, and reconnect wiring.
Step 4 – Check for overheating causes: Clean lint from the blower housing and vent system to prevent future overheating.
