The Goodman 20197312 Pressure Switch is a factory OEM combustion-safety control for the WGFM195070S3BAC gas furnace and compatible Goodman/Amana models. This normally-open switch proves adequate draft before the control board allows ignition, closing at a -0.37 in. WC set point when the inducer establishes proper negative pressure.

When a pressure switch drifts out of calibration or fails closed/open, the furnace throws draft-proving faults, fails to ignite, or lockouts intermittently. An exact-spec OEM replacement restores the correct trip point so the ignition sequence completes reliably.

Specifications

  • Part Number: 20197312
  • Type: Air-proving / draft pressure switch
  • Set Point: -0.37 in. WC (water column)
  • Contact Configuration: Normally Open (NO)
  • Brand: Goodman (OEM)
  • Fits: WGFM195070S3BAC and select Goodman/Amana furnaces

OEM vs. Generic

Pressure-switch calibration is measured in hundredths of an inch of water column. Our genuine OEM Goodman switch ships at the factory -0.37" set point your control board is programmed to expect. Universal switches with adjustable or approximate ratings frequently cause false lockouts or, worse, mask a real venting problem. For a safety-critical part, OEM precision is essential.

Installation Difficulty

Easy–Moderate (2.5/5). About 15 minutes: cut power, transfer the hose and two spade terminals, and mount the new switch in the original orientation. Verify the sensing hose is clear and free of condensate so the switch reads accurate pressure.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman WGFM195070S3BAC — 20197312?
Yes. This is the factory-specified OEM pressure switch for the Goodman WGFM195070S3BAC — 20197312. 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 WGFM195070S3BAC — 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.
