OEM Goodman -0.60 in WC NO Pressure Switch for WGFM195115S5DAD — 20197310

Goodman 20197310 Air Pressure Switch (-0.60 in WC, NO)

The Goodman 20197310 is a genuine OEM air-proving pressure switch calibrated at -0.60 inches of water column with a normally-open (NO) contact configuration. It is the factory-specified switch for the WGFM195115S5DAD gas furnace. This switch confirms proper draft-inducer airflow before the control board allows ignition — a critical safety interlock that prevents the burner from firing if the vent or condensate path is blocked.

OEM vs. Generic

Pressure switches are calibration-critical — the set point and contact logic must match exactly. The OEM 20197310 is factory-trimmed to -0.60 in WC, so it proves and releases at the pressures the Goodman control board expects. A mismatched generic switch (wrong set point or NC vs. NO) will cause lockouts or, worse, defeat the safety. Always match the -0.60 rating stamped on the original.

Install Difficulty

Easy–Moderate (2/5). Remove the hose and two spade terminals, unscrew the switch, and reverse. About 20–30 minutes. Verify the -0.60 rating and hose port orientation. Shut off power and gas first.
