The Goodman 20197312 Pressure Switch is a genuine OEM replacement engineered for AMH950905DXAB gas furnaces and compatible Amana/Goodman 95% AFUE models. This normally-open (NO) air-proving switch monitors negative pressure in the combustion venting system and closes at a set point of -0.37 inches of water column (WC), allowing the ignition sequence to proceed only when the inducer draft is verified. A failed or drifting pressure switch is one of the most common causes of a furnace that ignites and quickly shuts off, or that locks out with a pressure-switch fault code.

Specifications

OEM Part Number: 20197312
Type: Single-stage, Normally Open (NO)
Set Point: -0.37" WC
Application: Draft/pressure proving on induced-draft gas furnaces
Fits: Goodman & Amana AMH950905DXAB and related 95% AFUE furnaces
Connection: Single hose port with spade terminals

OEM vs. Generic

This is the factory-specified OEM switch, calibrated to the exact trip point your furnace's control board expects. Universal or generic switches often carry a different set point, which can cause nuisance lockouts or, worse, allow ignition under unsafe draft conditions. For a safety-critical air-proving component, we strongly recommend OEM.

Installation

Difficulty: Easy (DIY-friendly, 15–20 min). Disconnect power, note the hose and wire routing, transfer the tubing and spade terminals to the new switch, and remount. Always verify draft operation after replacement. If you are unsure about combustion safety, use a licensed HVAC technician.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMH950905DXAB — 20197312?

How do I replace the pressure switch on my Goodman AMH950905DXAB — 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.
