Description
Carrier HH18HA185 Limit Switch
The Carrier HH18HA185 is a genuine OEM limit switch engineered to provide dependable overheat protection in Carrier furnace systems. Limit switches are a critical safety component — they monitor heat exchanger temperatures and shut down the burner circuit if temperatures exceed safe operating thresholds, protecting both the equipment and the building occupants.
Product Overview
Designed as a direct OEM replacement for compatible Carrier furnace models, the HH18HA185 limit switch ensures your system operates safely and efficiently. When the furnace reaches an unsafe temperature, the limit switch opens the control circuit to interrupt burner operation until temperatures return to a safe range. Using a genuine Carrier replacement part ensures proper fit, function, and reliability.
