Product Details

Description

This premium Air Pressure Switch is a vital safety component for high-efficiency HVAC systems and furnaces. Designed as a two-port air proving switch, it plays a critical role in monitoring the pressure differential created by the draft inducer motor. By ensuring that exhaust gases are being properly vented, this switch allows the heating cycle to proceed safely. If your furnace or air handler is failing to ignite or experiencing intermittent shutdowns, a faulty pressure switch may be the cause. This replacement part is calibrated to a 0.50" WC (Water Column) set point, providing precise detection to maintain optimal combustion and prevent hazardous operation. Built for durability and reliability, it is an essential part for maintaining the performance of residential and commercial heating equipment.
