The 5/8" Disc Auto Reset High Limit Control Switch is a vital safety component for residential HVAC systems and furnaces. This thermal limit switch is designed to monitor and regulate the internal temperature of heating equipment, acting as a protective cutout to prevent overheating. It features an automatic reset mechanism that opens the electrical circuit when the temperature reaches a specific high-heat threshold and automatically closes once the system has cooled down sufficiently. This fan disc switch is essential for maintaining the integrity of your heat exchanger and ensuring the safe operation of your air handler or blower motor. If your furnace is cycling on and off too frequently or failing to provide heat, a worn limit control may need replacement to restore proper thermal safety and system efficiency.
