Product Details

Description

This premium air pressure switch is a vital safety component designed for high-performance gas furnaces and rooftop HVAC units. Functioning as an air proving switch, it monitors the pressure differential created by the inducer motor to ensure proper airflow and venting before the ignition process begins. If your heating system is experiencing ignition failure or pressure switch lockout errors, this 4.5 inch WC sensor provides a reliable solution to restore safe operation. Built to detect critical pressure thresholds, this component prevents the operation of the burner under unsafe venting conditions, protecting your equipment and ensuring efficient combustion throughout the heating cycle.
