Product Details

Description

This high-performance air pressure switch is a critical safety component for HVAC and gas furnace systems. Designed as an air proving switch, it monitors the venting process to ensure the inducer motor is creating sufficient airflow before allowing the ignition sequence to proceed. Calibrated for a 0.60" WC set point on a pressure rise, this Single Pole Normally Closed (SPNC) switch helps prevent unsafe operation by detecting venting obstructions or motor failures. If your heating system is experiencing ignition failure or pressure switch-related fault codes, this reliable replacement part is essential for restoring safe and efficient furnace performance. It is built to meet rigorous safety standards for residential and light commercial heating applications.
