Product Details

Description

The Reverse Flow High Limit Control Switch is a critical safety component designed for HVAC systems, specifically furnaces and air handlers. This fan disc style sensor acts as a thermal safeguard by monitoring internal temperatures to prevent the heating unit from overheating. If air temperatures exceed a safe operating threshold, this limit control automatically interrupts the electrical circuit, shutting down the system to prevent damage or fire hazards. It is an essential replacement part for restoring the safe and efficient operation of residential heating equipment. Engineered for reliability, this high-limit switch ensures that your heating system maintains a safe environment while providing consistent climate control performance.
