Goodman 20197308 Furnace Pressure Switch

The Goodman 20197308 is a genuine OEM negative-pressure (air-proving) switch engineered specifically for the GMH950904CXAE 96% AFUE two-stage gas furnace and compatible Goodman/Amana models. This switch monitors draft in the induced-draft venting system and safely locks out ignition if adequate airflow is not detected — protecting your home from incomplete combustion and flue blockages. A weak, stuck, or failed pressure switch is one of the most common causes of a furnace that ignites briefly then shuts down, or that never fires at all.

Specifications

Trip Point: -0.10 in. W.C. (inches water column)
Configuration: Normally Open (NO), single stage
Type: Negative air-proving / draft safety switch
Fits Model: GMH950904CXAE and select Goodman/Amana 96% furnaces
Brand: Genuine Goodman OEM

OEM vs. Generic

The genuine Goodman 20197308 is calibrated to the exact -0.10 in W.C. trip point specified by the manufacturer, ensuring your furnace's safety lockout behaves as designed. Generic replacements often carry looser calibration tolerances that can trigger nuisance lockouts in cold weather or, worse, fail to trip when they should. For a life-safety component, OEM is strongly recommended.

Installation

Difficulty: Moderate (2/5). Replacement involves shutting off power and gas, disconnecting the two spade terminals and the rubber draft-sensing hose, and swapping the switch — typically 15–20 minutes. Verify the correct trip rating stamped on the old switch before installing, and test furnace operation through a full heat cycle afterward. If you are not comfortable working around gas appliances, hire a licensed HVAC technician.

Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.

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

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