The Goodman 0130F00001P Pressure Switch is a genuine OEM combustion air-proving safety switch rated at -1.2" water column (WC), wired normally open (NO), for AKSS920453BXAA gas furnaces and compatible Goodman/Amana models. It senses negative pressure from the inducer draft blower and closes to confirm proper venting before the ignition sequence begins. If draft is insufficient—due to a blocked flue, failing inducer, or clogged condensate drain—the switch stays open and prevents ignition, protecting your home from unsafe combustion.
Pressure switch calibration is safety-critical. The genuine OEM 0130F00001P is factory-set to the exact -1.2" WC trip point your furnace requires. A generic switch with a different set point can cause hard lockouts or, worse, allow ignition under poor draft conditions. Always match the OEM rating stamped on the original switch.
Easy to Moderate. About 15–20 minutes. Cut power, note and transfer the wire terminals, disconnect the rubber sensing hose, unscrew the old switch, mount the replacement, and reconnect the hose and wiring. Confirm the switch closes and the furnace runs a full heat cycle.
Restore safe, reliable ignition with a genuine Goodman pressure switch.
