This 3/4-inch disc limit switch is a vital safety component for residential heating systems and HVAC equipment. Designed to function as a high-limit control, this thermal sensor monitors the internal temperature of your furnace or air handler to prevent overheating. It features an automatic reset function that opens the electrical circuit when the temperature reaches its 145°F limit and automatically closes once the temperature drops by 40°F. Replacing a faulty or failing limit switch is essential for maintaining safe furnace operation, protecting the heat exchanger, and ensuring the blower motor operates correctly. This durable fan disc switch is a standard replacement part for many forced-air heating applications where temperature regulation is critical for system longevity and home safety.
