Product Details

Description

This premium air pressure switch is a vital safety component for high-efficiency gas furnaces and HVAC systems. Designed as an air proving switch, it monitors the pressure differential created by the draft inducer motor to ensure that combustion gases are being properly exhausted before allowing the heating cycle to begin. Rated at 0.63" WC, this sensor helps prevent hazardous operation during vent blockages or inducer motor failures. If your furnace is experiencing ignition issues, failing to start, or shutting down unexpectedly, replacing a faulty air pressure switch can restore safe and efficient heating performance. This part is engineered for precision and durability, making it an essential replacement for maintaining your climate control system's reliability.
