Product Details

Description

This dual-stage air pressure switch is a vital safety component for high-efficiency two-stage gas furnaces. Engineered as an air-proving switch, it monitors the draft inducer motor to ensure proper airflow and venting before the ignition process begins. By accurately sensing pressure differentials at two distinct levels—0.90" WC and 1.30" WC—this switch facilitates the transition between low-fire and high-fire heating cycles. A malfunctioning pressure switch is a common cause of furnace ignition failure or intermittent shutting down. Replacing a faulty switch with this high-precision SPST (Single Pole Single Throw) component helps restore heating system reliability, ensuring safe combustion and optimal energy efficiency for your residential HVAC system.
