The genuine Goodman 20197308 pressure switch is an OEM air-proving (draft) switch calibrated to -0.10 inches of water column (WC) with a normally open (NO) contact. It confirms proper induced-draft airflow before the furnace allows ignition, and it is a direct fit for the GMV951155DXBA two-stage variable-speed condensing furnace and related GMV9-series models.

Specifications

OEM Part Number: 20197308
Set Point: -.10 in WC (water column)
Contact Configuration: Normally Open (NO)
Function: Induced-draft / vent-pressure proving switch
Primary Fit: Goodman GMV951155DXBA
Type: Factory OEM replacement

OEM vs. Generic

Pressure switches are calibration-critical. The OEM 20197308 is factory-set to the exact -.10 WC trip point your furnace's control board expects. A generic switch with a slightly different set point or contact type can cause nuisance lockouts, delayed ignition, or a furnace that never fires. Because this component is a safety device, we strongly recommend the OEM part over a universal substitute.

Installation Difficulty

Easy to Moderate (2 of 5). Replacement involves disconnecting the pressure tubing and two spade terminals, then mounting the new switch in the same orientation. Verify the hose is free of condensate and the port faces correctly. Test for proper ignition sequence after installation. If lockout codes persist, have a licensed technician inspect the inducer and venting.

Replacing a stuck-open or drifted pressure switch restores reliable ignition and clears common furnace fault codes.

How do I replace the pressure switch on my Goodman GMV951155DXBA — 20197308?

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?

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.

The same physical part is often used across brand labels with different model numbers.

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