Genuine Goodman 20197311 Pressure Switch (-.60" WC, NO)

The OEM Goodman 20197311 air pressure switch is a factory safety control for the Goodman GCH90703BXAB gas furnace. This normally-open switch monitors draft-inducer vacuum and closes when adequate airflow is confirmed, permitting the ignition sequence to proceed. If venting is blocked or the inducer is weak, the switch stays open and locks out the burners — protecting against incomplete combustion and flue-gas spillage. A failed switch is a leading cause of furnace no-heat and repeated ignition lockouts.

Part Type: Air Pressure / Draft Switch
Set Point: -0.60 in. WC (water column)
Configuration: Normally Open (NO), single-stage

OEM vs. Generic

This genuine Goodman OEM switch is calibrated to the exact -0.60" WC trip point required by your furnace. Pressure switch set points are model-specific — installing a switch with the wrong rating or contact configuration will cause nuisance lockouts or defeat the safety interlock. OEM guarantees the correct set point, port size, and NO/NC configuration.

Installation Difficulty

Moderate (2/5). Remove the mounting screw, transfer the vacuum hose and spade terminals, and confirm the hose seats fully. Cut power before servicing and verify the -0.60" WC rating stamped on the switch matches the original.

My furnace shows a pressure switch error. What do I replace?

Should I use OEM or aftermarket for my Goodman pressure switch?
