Goodman 20197308 Pressure Switch (-0.10" WC, Normally Open)

The Goodman 20197308 pressure switch is the OEM air-proving control for the GMH950703BXAF 95% AFUE furnace. This normally-open switch senses inducer draft and closes at approximately -0.10 inches water column (WC), telling the control board the venting is clear before the igniter and gas valve are allowed to energize. A stuck-open switch is one of the most common causes of no-heat / lockout codes on Goodman condensing furnaces.

Specifications

Function: Draft/air-proving pressure switch
Set point: -0.10" WC
Contact type: Normally Open (closes on draft)
Fitment: Goodman/Amana GMH95 and related condensing furnaces using 20197308
OEM Part #: 20197308

OEM vs. Generic

The OEM Goodman 20197308 is factory-calibrated to the exact -0.10" WC trip point your control sequence expects — critical for reliable ignition and safe venting. Our generic-equivalent switch carries the same set point and port style at a lower price, ideal for out-of-warranty repairs. Both are new and bench-tested.

Installation Difficulty

Easy (1 of 5). One or two mounting screws, one silicone sensing hose, and two spade terminals. Cut power first, verify the hose and inducer port are clear of condensate before blaming the switch. Typical job time: 15 minutes.

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