The Goodman 20197308 Pressure Switch is a genuine OEM combustion-air/draft safety switch engineered for the AMH950704CXAE gas furnace and other compatible Goodman and Amana models. This normally-open switch monitors inducer draft and will not allow ignition until proper venting airflow is confirmed, protecting your home from unsafe combustion conditions.

Rated at a -.10 in. W.C. actuation setpoint, this switch closes on a rise in negative pressure to prove the induced-draft blower is pulling flue gases correctly. A failed or drifting pressure switch is one of the most common causes of a furnace that lights briefly then shuts off, or that fails to ignite at all.

OEM vs. Generic

Choose the OEM 20197308 for a factory-calibrated setpoint and guaranteed fit — critical for a safety component where an incorrect trip pressure can cause nuisance lockouts or unsafe operation. Generic universal switches may require re-tubing or bracket adaptation and are not calibration-matched to this furnace's inducer. For a safety device, we strongly recommend OEM.

Install Difficulty

Easy (1 of 5). Disconnect power, photograph and transfer the wire leads and pressure tubing, mount with the same screws, and restore power. Most homeowners complete this in 15–20 minutes. Always cut power at the disconnect before servicing.

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

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

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