Goodman 20197312 Air Pressure Switch (-0.37" WC, Normally Open)

The Goodman 20197312 is the genuine OEM air-proving pressure switch for the GKS90453BXAA 90%+ AFUE gas furnace. This safety switch verifies that the inducer draft motor is moving combustion air before the control board allows ignition. It is a single-pole, normally open switch that closes at a set point of -0.37 inches of water column. If the switch fails to close — due to a bad switch, blocked flue, clogged condensate trap, or a cracked hose — the furnace locks out on a pressure-switch fault and will not fire, protecting the home from unsafe combustion.

Part number: 20197312
Set point: -0.37 in. WC
Action: Normally open (SPST, closes on negative pressure)
Fits: Goodman GKS90453BXAA and compatible GKS9 furnaces
Function: Combustion-air / draft proving safety

OEM vs. Generic

Pressure switches are calibrated to a specific set point — using a generic switch with the wrong pressure rating causes nuisance lockouts or, worse, defeats the safety interlock. The OEM 20197312 is factory-matched to the GKS90453BXAA inducer and flue design, so it proves draft at exactly the pressure Goodman engineered for.

Installation Difficulty: Easy

Rated Easy (2 of 5). Cut power to the furnace, photograph the wiring, transfer the two spade terminals and the sensing hose to the new switch, and mount with the original screws. Confirm the hose is clear and free of condensate. About 20–30 minutes. Follow all Goodman and local code requirements.

How do I replace the pressure switch on my Goodman GKS90453BXAA — 20197312?

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.

Is this pressure switch compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

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

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
