Goodman 20197308 Pressure Switch (-.10" WC, Normally Open)

The Goodman 20197308 is a genuine OEM pressure switch for the GMV91155DXBA two-stage variable-speed 96% AFUE furnace and compatible Goodman/Amana models. On a two-stage furnace, this lower -.10 in. WC switch proves adequate draft during low-fire (first-stage) operation, while a second, higher-set switch confirms high-fire. It ensures the inducer is moving enough combustion air before the board allows ignition.

Specifications

Set point: -0.10 in. WC (water column)
Action: Normally Open (NO)
Function: Low-fire draft/pressure proving
Fit: Goodman GMV91155DXBA two-stage furnaces
OEM Part Number: 20197308

OEM vs. Generic

Because two-stage furnaces rely on tightly matched switch pairs, the OEM Goodman unit is strongly preferred — its factory calibration keeps low-fire and high-fire proving in the correct relationship. Generic switches with loose tolerances frequently cause intermittent low-fire lockouts that are difficult to diagnose. Choose OEM.

Install Difficulty

Moderate. Two spade terminals, one or two screws, and a silicone hose — about 15–25 minutes. Confirm you're replacing the correct switch (verify the -.10" marking) and label hoses before removal. Shut off power and gas first.

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

Should I use OEM or aftermarket for my Goodman pressure switch?
