The Goodman 20197312 Pressure Switch (-.37" WC, Normally Open) is a genuine OEM draft-proving safety control for the GMH950704CXAB and related Goodman/Amana furnaces. This switch verifies that the inducer/draft motor has established proper venting before the ignition sequence begins. When the correct negative pressure (-0.37 inches of water column) is sensed, the normally-open contacts close and allow the furnace to fire. A failed switch or a blocked vent will keep the furnace from igniting — a frequent no-heat cause.

OEM vs. Generic

OEM Goodman pressure switches are factory-calibrated to the precise set point your furnace's venting requires. Generic switches with a nominally similar rating can vary in actual trip pressure and hose-port size, causing nuisance lockouts or unsafe bypass of the draft-proving check. For a combustion safety control, OEM calibration matters — choose OEM.

Installation Difficulty

Easy (1/5). Typically a two-screw mount with one tubing hose and two wires, about 20 minutes. Shut off power and gas, note wire and hose placement, and confirm the tubing is free of moisture or blockage before restarting.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman GMH950704CXAB — 20197312?

Yes. This is the factory-specified OEM pressure switch for the Goodman GMH950704CXAB — 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 GMH950704CXAB — 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.
