Product Details

Description

Ensure the safety and efficiency of your heating system with this high-performance 3-inch High Limit Switch. This critical safety component is designed for residential furnaces and HVAC units to prevent the system from overheating. The L200-20F thermal control monitors the temperature of the heat exchanger, automatically opening the electrical circuit if the temperature reaches 200°F. It features a 20°F differential, meaning it will reset and restore power once the system cools to 180°F. Replacing a faulty limit sensor is essential for preventing short-cycling and protecting your furnace from internal damage. This reliable thermal cutout is a must-have for HVAC maintenance and furnace repair, providing peace of mind and consistent climate control.
