The Goodman 20197312 Air Pressure Switch is a genuine OEM safety control for the Goodman GMH950905DXAC gas furnace. Rated at -.37 in. WC (normally open), it senses negative pressure created by the inducer/draft blower and confirms that combustion venting is clear before the control board allows ignition. If the vent is blocked or the inducer fails, the switch stays open and safely prevents the burners from firing.

Specifications

Part type: Air proving / vent pressure switch
OEM Part Number: 20197312
Set point: -.37 in. water column (WC)
Action: Normally Open (NO), closes on pressure
Fits: Goodman GMH950905DXAC (95% AFUE furnace)
Fit: Direct OEM replacement — factory tubing port

OEM vs. Generic

Pressure switches are calibrated to an exact set point. The OEM 20197312 is factory-matched to the -.37" WC trip value this furnace requires; installing a generic switch with a different rating causes chronic ignition lockouts, short cycling, or — worse — bypassed safety limits. For a life-safety combustion control, always use the correctly rated OEM part.

Installation Difficulty

Easy (2/5). Roughly 15–25 minutes. Cut power, photograph the wiring, transfer the two spade terminals and the sensing hose to the new switch, then mount it. Confirm the hose is fully seated and free of condensate before restarting — a kinked or wet hose is the most common cause of a false open.

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?
