Description
The Carrier HH680368 is an OEM replacement L200F high-limit switch engineered to protect Carrier furnaces and air handlers from dangerous overheating conditions. When supply air temperatures exceed the rated threshold, this limit switch opens the control circuit, shutting down the burner and preventing heat exchanger damage or fire hazards. Once temperatures return to a safe operating range, the switch resets to restore normal system operation.
Key Features
- OEM Carrier replacement part — ensures proper fit and reliable performance
- L200F rating — opens on temperature rise at 200°F to protect against overheating
- Designed for use in Carrier furnaces and forced-air heating systems
- Interrupts burner operation upon detecting excessive heat, safeguarding the heat exchanger
- Helps maintain system efficiency and extends equipment service life
- Direct drop-in replacement for simplified installation
Application
The HH680368 limit switch is a critical safety component in Carrier furnace systems. It continuously monitors air temperature within the heat exchanger plenum and acts as a fail-safe by cutting power to the burner circuit if temperatures climb beyond the safe operating limit. This prevents costly heat exchanger failures, reduces fire risk, and keeps your system running safely and efficiently.
