Product Details

Description

Ensure your residential furnace operates at peak safety and efficiency with this premium Air Pressure Switch. Designed as a critical air-proving component for high-efficiency heating systems, this high-pressure switch monitors the airflow within the inducer motor housing. It is precisely calibrated to a 0.27" WC (Water Column) set point, acting as a vital safety mechanism that verifies proper venting and exhaust flow before allowing the furnace ignition process to begin. If your HVAC system is experiencing ignition failure or pressure switch lockout codes, this replacement sensing switch is essential for restoring reliable heat and preventing hazardous operating conditions. Built for durability and precision, it provides a reliable response to pressure changes within the heat exchanger environment.
