Product Details

Description

This high-performance Fan Disc High Limit Control Switch is a critical safety component designed for HVAC systems, including residential furnaces and air handlers. This thermal limit switch monitors internal temperatures to prevent the system from overheating, ensuring safe and efficient operation. It features an automatic reset mechanism that cuts off power to the heating element or burner when the temperature reaches 170°F (cut-out) and automatically restores operation once the system cools down to 140°F (cut-in). Replacing a faulty limit control is essential for resolving issues with short-cycling, inconsistent heating, or safety lockouts, helping to extend the lifespan of your heating and cooling equipment.
