This premium auto-reset limit switch is an essential safety component for HVAC systems and forced-air heating units. Designed as a high-limit control switch, it monitors internal temperatures to prevent equipment overheating and potential damage. The fan disc switch is engineered to automatically trip and open the electrical circuit when the temperature reaches 140°F, providing immediate thermal protection. Once the system cools down to 100°F, the switch resets itself to restore normal operation. This reliable temperature control is a common replacement part for furnaces and air handlers that are cycling improperly or failing to maintain consistent heating cycles. Replacing a worn or faulty limit switch ensures your heating system operates safely and efficiently throughout the season.
