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

The Goodman 20197312 air pressure switch is a factory-original draft-proving control for the GKS90905DXAA gas furnace. It confirms that the inducer (draft) motor is pulling proper combustion airflow before the ignition sequence begins. If venting is blocked, the trap is clogged, or the inducer is weak, the switch stays open and the control board safely aborts ignition — a core safety interlock on every condensing furnace.

Specifications

Actuation setpoint: -0.37" WC (inches water column)
Contact configuration: Normally Open (NO), closes on negative pressure
Fits: Goodman GKS90905DXAA and compatible 90%+ furnaces
OEM Part Number: 20197312
Brand: Goodman / Amana
Function: Proves inducer draft before burner ignition

OEM vs. Generic

Pressure switches are calibrated to a precise trip point, and the -0.37" WC rating on this genuine Goodman OEM part is matched to your furnace's vent design. Installing a switch with the wrong setpoint causes chronic no-heat lockouts or, worse, allows the burner to fire with inadequate venting. Always match the exact setpoint and NO/NC configuration — do not substitute.

Installation Difficulty

Easy (2/5). About 15 minutes. Cut power, photograph the wire terminals and hose connection, remove the mounting screws, and transfer the rubber pressure tube to the new switch in the same position. Inspect the tube and port for condensate or debris before restarting — a plugged hose mimics a failed switch.

Disconnect power before servicing. Verify the setpoint stamped on the switch matches -0.37" WC.

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.
