The Carrier HH18HA597 is a genuine Carrier replacement limit switch carrying the L160F designation, which indicates a 160°F limit setting. The limit switch is a safety control that monitors temperature at its mounting point and opens the circuit to the gas valve or heating control when the temperature exceeds the limit, preventing the equipment from overheating.
A limit switch that opens too early causes short heating cycles, while one that has failed open keeps the burners from running at all. Replace it only with a switch of the same temperature rating and mounting style. Confirm part number HH18HA597 against your equipment's parts list before ordering.
