Product Details

Description

This 3-inch high limit switch is a vital safety component designed for modern HVAC systems and forced-air furnaces. Engineered to prevent equipment overheating, the L150-30F thermal control monitors the internal plenum temperature of your heating unit. When the temperature exceeds the safe operating threshold of 150°F, the switch automatically opens to break the electrical circuit, protecting the heat exchanger and surrounding components from thermal damage. Once the system cools down by 30°F, the switch resets to restore normal functionality. This replacement sensor is essential for maintaining furnace reliability, ensuring home safety, and optimizing the performance of your residential or commercial heating system.
