Ensure your heating system operates safely with this 3-inch High Limit Switch. Designed as a critical safety cutoff for gas furnaces and HVAC units, this thermal sensor monitors the temperature within the heat exchanger to prevent overheating. The L160-20F model is engineered to trip and interrupt power to the burner if the internal temperature reaches 160 degrees Fahrenheit, protecting your equipment from heat-related damage and potential fire hazards. Once the unit cools by a 20-degree differential, the switch allows the system to resume normal operation. This high-limit control is a vital replacement part for maintaining furnace reliability and home safety in various forced-air heating applications.
