The Goodman 20197308 pressure switch is a genuine OEM air-proving safety switch calibrated to -0.10 inches of water column (WC) with a normally-open (NO) contact configuration. It is a direct-fit replacement for the Amana/Goodman AMVC950453BXAA high-efficiency variable-speed furnace. This switch confirms proper draft and venting airflow before allowing ignition — protecting against dangerous combustion conditions. A failed pressure switch is one of the most common reasons a furnace won't ignite or short-cycles.

OEM vs. Generic

Pressure switches are calibration-critical. The OEM 20197308 is factory-set to the exact -0.10" WC trip point your furnace's control board expects. Generic switches with even slightly different setpoints cause nuisance lockouts or, worse, allow ignition under unsafe draft. Always match OEM for safety components.

Installation Difficulty

Easy–Moderate (2 of 5). Roughly 20–30 minutes. Power off the furnace, note the tubing and wire positions, transfer the hose and spade connectors to the new switch, and mount. Because this is a safety device, we recommend verification by a licensed HVAC technician.

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?
