Goodman 20197308 Pressure Switch (-.10" WC, NO)

The Goodman 20197308 is a genuine OEM air proving pressure switch for the Amana/Goodman AMVC951155DXAB two-stage variable-speed 95% furnace. This normally-open switch closes at a -.10 inch water column set point to verify adequate combustion airflow during the low-fire (first-stage) heating cycle. Paired with the high-fire switch, it forms part of the furnace's staged safety-proving sequence, ensuring the inducer and flue are drafting before ignition is permitted.

Specifications

Part Number: 20197308
Set Point: -0.10 inch W.C.
Contact Type: Normally Open (NO)
Function: Proves low-fire combustion airflow / venting
Fit: AMVC951155DXAB and compatible Goodman/Amana 95% furnaces

OEM vs. Generic

The low-fire stage relies on a precise -.10" trip point — OEM 20197308 is calibrated to that exact value. Generic switches with incorrect set points cause intermittent low-fire lockouts that are difficult to diagnose. For dependable two-stage operation, OEM is the recommended choice.

Installation Difficulty

Easy to Moderate. Disconnect power, move the silicone hoses and spade terminals to the matching new switch, and re-mount. Confirm hose ports are free of condensate, then verify continuity with a multimeter before restoring power.
