The Goodman 20197312 Pressure Switch is a genuine OEM air-proving control rated at -0.37" WC (normally open) for the AMH950703BXAD gas furnace and compatible Goodman/Amana models. It senses negative pressure created by the inducer/draft motor and closes to confirm safe venting airflow before the furnace allows ignition — a required safety interlock in the sequence of operation.

A failed switch that won't close, or one tripping on a blocked flue or clogged drain, produces no-heat calls and inducer-runs-but-no-ignition symptoms. This exact-spec OEM switch restores reliable draft proving.

Specifications

OEM Part Number: 20197312
Set Point: -0.37" WC (water column)
Configuration: Normally Open (NO), closes on draft
Fits: Goodman/Amana AMH950703BXAD furnace

OEM vs. Generic

The OEM pressure switch is calibrated to the precise -0.37" set point and port style this furnace requires. A mismatched set point defeats the safety function and causes intermittent lockouts. For pressure/safety switches, OEM is strongly recommended.

Installation Difficulty

Easy to Moderate — cut power, transfer the tubing and spade connectors to the new switch, and mount with the existing screws. Verify operation with a manometer or by confirming a normal ignition cycle.
