This high-performance air pressure switch is a critical safety component designed for HVAC heating systems and gas furnaces. Functioning as an air proving switch, it monitors the pressure differential created by the draft inducer motor to ensure proper airflow and venting before allowing the combustion process to begin. If your furnace is failing to ignite or experiencing frequent cycle interruptions, a faulty pressure sensor may be the cause. This switch features precision-calibrated set points of 0.70" WC, 1.00" WC, and 0.40" WC to maintain optimal system efficiency and safety. Built for durability, this replacement part helps prevent hazardous conditions by ensuring the exhaust system is clear and operational. It is an essential component for technicians and homeowners looking to restore reliable heating performance during the winter months.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
