Product Details

Description

This premium 2-stage air pressure switch is a vital safety component for high-efficiency gas furnaces and HVAC systems. As an essential air proving switch, it monitors the vacuum pressure created by the draft inducer motor to ensure that combustion gases are being properly vented before allowing the furnace to ignite. If your heating system is experiencing ignition failure or intermittent shut-offs, a malfunctioning pressure switch is often the culprit. This dual-stage replacement is precision-calibrated to detect specific pressure thresholds, ensuring your multi-stage furnace operates at peak efficiency and safety. Built for durability and reliability, it serves as a critical safeguard against hazardous exhaust buildup in residential heating applications.
