Goodman 20197308 Pressure Switch (-0.10" WC, Normally Open)

The Goodman 20197308 is the factory air-proving pressure switch calibrated for the GMH950704CXAF 96% AFUE two-stage gas furnace. This switch verifies that the inducer draft motor is moving combustion gases before the control board allows ignition. It is a normally-open (NO) switch rated to close at approximately -0.10 inches of water column. If the switch fails to close, the furnace will lock out and refuse to fire — protecting your home from unsafe combustion conditions.

Specifications

OEM Part Number: 20197308
Type: Air-proving / draft pressure switch
Setpoint: -0.10 in. W.C. (negative pressure)
Action: Normally Open (NO), closes on draft
Primary Fit: Goodman GMH950704CXAF

OEM vs. Generic

Pressure switches are calibration-critical. The genuine Goodman 20197308 is factory-set to the exact -0.10" trip point your board expects. Generic switches with a different setpoint or port count can cause nuisance lockouts, short cycling, or — worse — allow ignition under poor draft. Always match the OEM setpoint stamped on the switch body.

Installation Difficulty

Easy–Moderate (2/5). Disconnect furnace power, photograph the wiring, transfer the two spade terminals and the rubber sensing hose to the new switch, then mount it in the original bracket. Verify the hose is free of condensate and kinks. Typically a 20–30 minute repair with a nut driver. Confirm proper ignition sequence after installation.

Genuine OEM safety component — do not defeat or jumper a pressure switch. Fast shipping from National HVAC Parts.

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

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