Product Details

Description

The 3-inch High Limit Switch (L200-20F) is a vital safety component designed for residential and commercial HVAC heating systems. This thermal limit control acts as a protective sensor, monitoring the temperature within the furnace heat exchanger. It is engineered to automatically interrupt the electrical circuit and shut down the burner if the internal temperature exceeds a safe threshold of 200°F, preventing potential damage to the unit and ensuring home safety. Featuring a 20°F differential, the switch resets once the system cools to 180°F. If your furnace is short-cycling or the blower motor continues to run without heat, this high-quality replacement limit switch is a primary troubleshooting component for restoring reliable performance and overheating protection.
