The Goodman 20197312 Air Pressure Switch is a genuine OEM safety control calibrated at -0.37 in. WC, normally open (NO), for the GMH950703BXAC high-efficiency furnace. This switch verifies proper draft-inducer airflow and venting before the furnace allows ignition, protecting your home from unsafe combustion and flue blockages.

Specifications

  • Part Number: 20197312
  • Set Point: -0.37 in. water column (WC)
  • Contact State: Normally Open (NO)
  • Function: Proves inducer draft / venting airflow
  • Compatibility: Goodman GMH950703BXAC and related condensing furnaces

OEM vs. Generic

The OEM switch is factory-calibrated to the exact -0.37" set point your furnace's control board expects, ensuring safe, code-compliant ignition sequencing. Generic switches may carry a nearby set point but small calibration differences can cause nuisance lockouts or, worse, mask a real venting problem. For a safety-critical control, OEM is strongly recommended.

Install Difficulty

Easy–Moderate (2.5/5). Replacement takes 20–40 minutes. Turn off power, photograph and disconnect the two spade terminals and the rubber sensing hose, unscrew the switch, and mount the new one. Reconnect the hose fully seated — a loose hose is the #1 cause of false pressure-switch faults.

Genuine Goodman reliability. In stock and shipping fast.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman GMH950703BXAC — 20197312?
Yes. This is the factory-specified OEM pressure switch for the Goodman GMH950703BXAC — 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 GMH950703BXAC — 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.
