This High Limit Control Switch is a vital safety component for residential and commercial heating systems. Designed as a fan disc style limit, it acts as a failsafe to prevent equipment overheating and potential damage. The switch is calibrated to open the circuit at 140°F (L140F), immediately cutting power to the heating element or burner if internal temperatures rise too high. With a 30°F differential, the control automatically resets once the temperature drops to a safe operating level, ensuring your furnace or HVAC unit continues to function efficiently. Whether you are performing routine maintenance or troubleshooting a heating cycle issue, this reliable limit control switch is essential for maintaining the safety and longevity of your heating appliance.
