Goodman 20197308 Pressure Switch (-0.10" WC, Normally Open)

This genuine OEM Goodman/Amana 20197308 air pressure switch is a direct-fit replacement for the AMV90704CXAB gas furnace and other compatible Goodman and Amana 90%+ AFUE models. The pressure switch is a critical safety control: it verifies that the inducer/draft blower is producing correct venting airflow before the ignition sequence is allowed to proceed, protecting your home from unsafe combustion conditions.

Specifications

OEM Part Number: 20197308
Trip Point: -0.10 inch water column (WC)
Contact Type: Normally Open (NO)
Application: Draft/inducer pressure proving
Fits Model: AMV90704CXAB (and compatible Goodman/Amana furnaces)
Brand: Genuine Goodman / Amana OEM

OEM vs. Generic

Our OEM 20197308 is factory-calibrated to the exact -0.10" WC trip point your furnace's control board expects, ensuring reliable ignition and lockout behavior. Aftermarket generic switches can carry loose calibration tolerances that cause nuisance lockouts, short cycling, or failed pressure-proving faults. For a life-safety component like this, the OEM part is the recommended choice.

Symptoms of a Failed Pressure Switch

Furnace fails to ignite, inducer runs but burners never light, or a flashing pressure-switch fault code on the control board. Replacing a worn or stuck 20197308 restores normal heating operation.

Installation Difficulty

Moderate — Requires disconnecting power, removing the switch mounting screws, and transferring the vinyl sensing hose to the exact same port. Verify hose routing and connector orientation. If you are not comfortable working around gas heating equipment, we recommend a licensed HVAC technician.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMV90704CXAB — 20197308?

How do I replace the pressure switch on my Goodman AMV90704CXAB — 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.
