The Goodman 20197312 Pressure Switch is a genuine OEM safety component engineered for the WGFM195090S5DAB modulating gas furnace and compatible Goodman/Amana models. This -0.37 inch W.C., normally-open (NO) switch monitors combustion draft and inducer airflow, proving that the venting system is operating within safe limits before the control board allows ignition. When the switch fails, the furnace typically locks out and will not fire — making this an essential no-heat repair part.

  • OEM Part Number: 20197312
  • Type: Air pressure / draft-proving switch
  • Setpoint: -0.37 in. W.C. (negative pressure)
  • Contact Configuration: Normally Open (NO)
  • Application: Gas furnace inducer/draft safety
  • Fits: Goodman WGFM195090S5DAB and related 95%+ AFUE furnaces

OEM vs. Generic: This is a factory-original Goodman switch calibrated to the exact -0.37" trip point the furnace's control logic expects. Generic switches may carry a similar rating but can drift out of spec, causing nuisance lockouts or bypassing a real safety condition. For a component tied directly to combustion safety, the OEM part delivers correct calibration and reliable long-term performance.

Install Difficulty: Moderate. Requires shutting off gas and power, removing the two spade wire connectors, unclipping the silicone hose, and swapping the switch on its bracket — typically 20–30 minutes. Verify hose routing is free of condensate and confirm proper firing on restart. If you are unsure about combustion safety testing, we recommend a licensed HVAC technician.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman WGFM195090S5DAB — 20197312?
Yes. This is the factory-specified OEM pressure switch for the Goodman WGFM195090S5DAB — 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 WGFM195090S5DAB — 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.
