The Carrier HH18HA509 is a limit switch used in furnaces and air handlers to monitor supply air or heat exchanger temperature. It opens its contacts to shut down the burner or blower if temperature rises above a safe range, trips between 155°F and 195°F, and resets automatically once the unit cools. This is a genuine Carrier replacement part.
Confirm this part number against your equipment's parts list before ordering.
