The Goodman 20197308 Pressure Switch is a genuine OEM draft-proving safety switch rated at -.10 inches of water column (in WC), normally open, built for the Goodman GMH950904CXAF 95% AFUE two-stage furnace and compatible GMH95 models. It verifies that the induced-draft blower is generating proper negative pressure before the ignition sequence begins. If venting is blocked, the trap is clogged, or the inducer is weak, the switch stays open and the control board locks out ignition — preventing unsafe combustion.

Specifications

Set point: -.10 in WC (water column)
Contact type: Normally Open (NO)
Function: Draft / negative-pressure proving safety switch
Fit: Goodman GMH950904CXAF and compatible GMH95 furnaces
OEM Part Number: 20197308
Brand: Goodman / Amana OEM

OEM vs. Generic

Pressure switches are only correct when the set point matches your furnace exactly. This factory-original switch is calibrated to -.10 in WC for the GMH950904CXAF's inducer and venting design. A generic switch with the wrong rating causes chronic short-cycling, nuisance lockouts, or — worse — allows operation under unsafe draft. Always match the OEM number and set point.

Installation Difficulty: Easy (2/5)

Turn off power, note the hose and wire positions, remove the mounting screw, and swap in the new switch. Reconnect the rubber pressure tube firmly and confirm no cracks or moisture inside it. Verify furnace operation through a full heat cycle afterward.

Genuine Goodman OEM pressure switch — exact -.10 in WC calibration for the GMH950904CXAF.

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