Carrier HH18HA499 Limit Switch Its high-temperature tolerance makes itThe Carrier HH18HA499 Limit Switch is a critical high temperature safety component engineered for Carrier, Bryant, and Payne gas furnaces. This automatic reset limit switch is designed to open the electrical circuit when internal plenum temperatures reach the 165F threshold and closes once temperatures normalize to 125F. It serves as a direct replacement for the HH18HA499A model, ensuring field compatibility and maintaining the original safety circuit
