Product Details

Description

This high-performance air pressure switch is a vital safety component for residential gas furnaces and HVAC heating systems. Designed as an air-proving switch, it monitors the venting system's pressure to ensure the inducer motor is creating sufficient draft for safe combustion. If the switch detects a pressure change outside of its -0.40" WC set point—often caused by a blocked flue or failing motor—it prevents the ignition sequence, protecting the system from improper venting. This replacement part is ideal for restoring reliable operation to heating units experiencing startup failures, inducer motor issues, or intermittent furnace shut-offs.
