This 3/4" Manual Reset High Limit Switch is a vital safety component for HVAC systems and residential furnaces. Designed to provide reliable thermal protection, this fan disc limit switch monitors internal temperatures and automatically interrupts the electrical circuit if the unit exceeds a safe operating threshold of 140°F. Because this is a manual reset switch, it requires a physical reset once the temperature drops, ensuring that a technician or homeowner can investigate the cause of the overheating before the system resumes operation. This high limit control is essential for preventing heat exchanger damage and ensuring the safe operation of forced-air heating equipment. It serves as a high-quality replacement part for maintaining system efficiency and protecting your heating unit from critical failure.
