Description
The Carrier HH18HA137 is an OEM automatic reset limit switch engineered to protect furnaces and heating systems from dangerous overtemperature conditions. When supply air temperatures exceed the set point, this limit switch interrupts the burner circuit, shutting down the heat source and preventing heat exchanger damage or fire hazards. Once temperatures return to a safe level, the automatic reset function restores normal operation without requiring manual intervention — minimizing downtime and service calls.

- Temperature range: 90°F to 130°F
- Genuine Carrier OEM replacement part (SKU: HH18HA137)
- Designed for precise, reliable overheat protection in Carrier furnaces and air handlers
