Description
The Carrier HH18HV135 is an automatic reset limit switch engineered to protect furnaces and heating systems from dangerous overheating conditions. Designed as a genuine Carrier OEM replacement part, this limit switch monitors heat exchanger temperatures and automatically interrupts the burner circuit when temperatures exceed the set threshold — then resets itself once safe operating temperatures are restored, minimizing system downtime.
Key Features
- Automatic reset operation — restores normal function once temperatures return to safe levels
- Temperature range: 110–135°F operating range for precise overheat protection
- Genuine Carrier OEM replacement part for reliable, like-for-like performance
- Protects heat exchanger and furnace components from thermal damage
- Direct-replacement design for straightforward installation
- Compatible with a wide range of Carrier furnace models
Application
The HH18HV135 limit switch is a critical safety component in forced-air furnaces. When the furnace plenum or heat exchanger temperature rises beyond the rated limit, the switch opens the control circuit to shut down the burner, preventing equipment damage and potential fire hazards. Its automatic reset function means the system can resume normal operation once temperatures drop back within the safe range — no manual intervention required.
