The Goodman 20197308 Pressure Switch is a genuine OEM -.10" W.C. normally-open (NO) draft-proving switch for the AMVC950704CXAA two-stage variable-speed 96% AFUE gas furnace and compatible Goodman/Amana models. It verifies that the induced-draft blower has established adequate negative pressure before the ignition sequence begins. When this switch is faulty or its hose is blocked, the furnace displays a pressure-switch code and will not light — a frequent no-heat complaint.

Part number: 20197308
Setpoint: -0.10" W.C.
Contact type: Normally open (NO), closes on draft
Function: Draft/vent safety proving
Fits: AMVC950704CXAA and compatible Goodman/Amana furnaces

OEM vs. Generic

As a calibrated safety switch, the -.10" trip point must match the furnace's inducer and venting design exactly. Generic switches with approximate setpoints risk nuisance lockouts or, worse, closing under insufficient draft. The genuine OEM 20197308 delivers the factory-specified -0.10" W.C. calibration and correct NO contact action.

Installation Difficulty: Easy

Rated Easy (2/5). The switch mounts with one or two screws; transfer the hose to the correct port and match the wiring terminals. Inspect the sensing hose for condensate or blockage during replacement. Have a licensed HVAC technician confirm draft pressure with a manometer.

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