The Goodman 20197310 Pressure Switch is the factory OEM air-proving safety switch for the GMH950904CXAC 96% AFUE gas furnace. Rated at -0.60 inches water column (WC) and configured normally open (NO), it confirms that the inducer draft motor is pulling adequate airflow before the control board allows the igniter and gas valve to energize. If the switch fails or the pressure tubing is blocked, the furnace will lock out and refuse to fire — a critical protection against unsafe combustion.

OEM Part #: 20197310
Set Point: -0.60 in. WC
Configuration: Normally Open (NO), single-pole
Fits: Goodman GMH950904CXAC and compatible high-efficiency furnaces
Function: Draft / air-proving safety switch

OEM vs. Generic: Pressure switches are calibrated to a specific negative-pressure set point. Installing a switch with the wrong WC rating or contact configuration will cause chronic short-cycling or bypass a required safety. This genuine Goodman switch is pre-calibrated to -0.60 in. WC and matches the original mounting and tubing connections exactly.

Install Difficulty: Easy (2/5). Cut power, note the wire terminals and hose position, unscrew the mounting screws, transfer the tubing and spade connectors to the new switch, and remount. About 15–20 minutes.
