The Goodman 20197308 Pressure Switch is a genuine OEM normally-open (NO) air-proving switch rated at -0.10 in. WC for the Goodman/Amana AMV90453BXAB gas furnace. This switch verifies that the induced-draft blower has established proper airflow before the control board energizes ignition. When the inducer pulls the required negative pressure, the normally-open contacts close, proving draft; if draft is insufficient — from a blocked flue, weak inducer, or plugged pressure port — the switch stays open and safely prevents the burner from firing.

  • Genuine OEM Goodman/Amana part number 20197308
  • Set point: -0.10 in. WC
  • Contact configuration: Normally Open (NO)
  • Induced-draft proving safety control
  • Direct fit for AMV90453BXAB and compatible furnaces

OEM vs. Generic: The OEM switch is factory-calibrated to the exact -0.10 in. WC trip point and matches the furnace's connector and mounting. Generic switches with approximate set points can cause pressure-switch lockout codes or, worse, prove draft when it isn't truly present. For a combustion-safety control, OEM calibration matters.

Install difficulty: Easy. Disconnect the low-voltage wire harness and the rubber pressure hose, unscrew the switch from its bracket, and reverse to install — about 15 minutes. Confirm the hose is seated with no cracks and verify with a manometer if possible. Always disconnect power before service.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMV90453BXAB — 20197308?
Yes. This is the factory-specified OEM pressure switch for the Goodman AMV90453BXAB — 20197308. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the pressure switch on my Goodman AMV90453BXAB — 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.
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.
