The Goodman 20197308 Pressure Switch is a genuine OEM air-proving switch for GMV951155DXBB 96% AFUE two-stage, variable-speed gas furnaces. This normally-open (NO) switch closes on a -0.10" water-column pressure drop, proving draft during low-stage (first-stage) operation before the control board permits ignition. Because two-stage furnaces use separate switches for each firing rate, a faulty low-stage switch can cause the furnace to fail on gentle first-stage calls while still firing on high stage — an intermittent no-heat symptom that's easy to misdiagnose.

Specifications

Part number: 20197308 (OEM Goodman/Amana)
Type: Normally Open (NO) air-proving pressure switch
Trip point: -0.10" WC (water column)
Application: Low-stage / first-stage draft proving
Fits: GMV951155DXBB and compatible Goodman two-stage furnaces
Connection: 1/4" hose port, spade terminals

OEM vs. Generic

The low -0.10" set point demands a precisely calibrated switch. This OEM part holds Goodman's exact trip pressure; generic equivalents commonly drift at such low pressures, producing nuisance lockouts on the lighter first-stage draft. OEM is recommended for consistent two-stage operation.

Installation Difficulty

Easy (2/5). A quick 15-minute swap — power down, move the hose and spade wires to the new switch, and mount. Confirm the -0.10" rating and low-stage position match your old switch before installing; a manometer check afterward is best practice.

How do I replace the pressure switch on my Goodman GMV951155DXBB — 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.

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?
