This high-quality Lennox high-limit control switch is an essential safety component for furnace and air handling units. As an auto-reset fan disc switch, it is designed to monitor and regulate the internal temperature of your heating system. The switch acts as a thermal protector, automatically interrupting the electrical circuit if the unit reaches 150°F to prevent overheating and potential damage. Once the system cools down by 40°F, the switch resets to restore normal operation. This replacement part is ideal for HVAC maintenance and repair, ensuring your heating equipment operates safely and efficiently. If your furnace is overheating or the blower fan is running continuously, replacing the limit control can restore proper system cycling.
