The Goodman 20197311 Pressure Switch is a genuine OEM safety component engineered for the GCH91155DXAE gas furnace and compatible Goodman/Amana models. This normally-open (N.O.) switch is calibrated to close at a set point of -0.60" water column (WC), proving adequate combustion-air and vent draft before the ignition sequence is allowed to proceed. A failing pressure switch is one of the most common causes of a furnace that ignites briefly then shuts down, or that fails to light at all.

  • Type: Normally Open (N.O.) air-proving / draft pressure switch
  • Set point: -0.60" WC (negative pressure)
  • Application: Goodman GCH91155DXAE gas furnace
  • Function: Verifies inducer draft & blocked-vent safety
  • Fit: Direct OEM replacement — plug-and-play

OEM vs. Generic: Our genuine OEM 20197311 switch is factory-calibrated to the exact -0.60" WC trip point Goodman specifies for this cabinet. Generic switches often carry looser tolerances that can cause nuisance lockouts or, worse, allow ignition under poor-draft conditions. For a safety device, matching the OEM calibration is strongly recommended.

Install difficulty: Easy (1/5). Replacement typically takes 10–15 minutes: power down the furnace, disconnect the two spade terminals and the rubber pressure tube, unscrew the mounting screws, and reverse for the new switch. No special tools required. Always confirm power is off at the breaker before servicing.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman GCH91155DXAE — 20197311?
Yes. This is the factory-specified OEM pressure switch for the Goodman GCH91155DXAE — 20197311. 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 GCH91155DXAE — 20197311?
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.
