The Goodman 20197312 Air Pressure Switch is a genuine OEM safety control calibrated at -0.37 in. WC (normally open) for the AMS950704CXAB high-efficiency gas furnace. This switch verifies that the inducer draft motor is generating adequate airflow before the ignition sequence begins. If it does not sense the correct negative pressure, the furnace safely locks out ignition — protecting the home from incomplete combustion and flue-gas spillage.

Specifications

OEM Part Number: 20197312
Type: Air proving / draft pressure switch
Set Point: -0.37 in. WC (water column)
Contact Configuration: Normally Open (NO)
Compatible Model: AMS950704CXAB (Goodman/Amana furnace)
Equipment Type: High-efficiency gas furnace

OEM vs. Generic

The OEM Goodman 20197312 is factory-calibrated to the precise -0.37 in. WC trip point required by this furnace's control board and venting design. A generic switch with a mismatched set point can cause false lockouts, short cycling, or — worse — fail to trip when draft is inadequate. Because this is a combustion-safety component, always match the exact OEM part and pressure rating.

Installation Difficulty

Easy to Moderate (2 of 5). Replacement takes about 20–30 minutes: shut off power and gas, disconnect the two spade terminals and the rubber sensing hose, unscrew the switch bracket, and install the new unit in the same orientation. Confirm the hose is seated with no kinks. If lockout codes persist after replacement, have a licensed HVAC technician inspect the inducer and venting.
