The Goodman 11112501S Pressure Switch is a genuine OEM safety control calibrated to -.33 in. water column, normally open (NO), for the Goodman WGGE4348A090MAB furnace. This switch proves that the induced-draft blower is moving combustion air correctly before the furnace allows ignition — a critical safety interlock. A failed switch is a common cause of furnaces that won't fire or that lock out mid-cycle.

OEM vs. Generic

Pressure switches must match the furnace's exact set point and contact configuration. An OEM 11112501S is factory-calibrated to -.33" WC, so it trips at precisely the right draft pressure. Generic or mismatched switches risk false lockouts or, worse, allowing ignition without adequate draft. OEM ensures safe, code-compliant operation.

Installation Difficulty

Easy — Disconnect power, unplug the two-wire connector, transfer the rubber hose to the new switch, and mount with the same screws. Most homeowners with basic tools can complete this in 15–20 minutes; verify the hose is free of condensate afterward.

My furnace shows a pressure switch error. What do I replace?

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Should I use OEM or aftermarket for my Goodman pressure switch?
