It monitors draft from the inducer motor and confirms the venting system is clear before allowing ignition. If it detects a blocked vent, weak inducer, condensate clog, or cracked hose, it prevents the burners from firing—protecting your home from unsafe combustion conditions. A failed or stuck pressure switch commonly causes no-ignition, furnaces that won't start, and pressure-switch fault codes. This factory-spec replacement matches the original trip point (inches of water column), port configuration, and bracket for accurate, dependable operation. Installation is moderately easy—about 20-30 minutes to swap the hose and electrical connectors and remount the switch. Always shut off power and gas, and inspect the vent and condensate lines for blockages before replacing. Restore safe, reliable startups and clear stubborn fault codes with this OEM part.
