The Goodman 11177117 Pressure Switch is a genuine OEM safety control for the GMV90703BXBA gas furnace. This normally-open (NO) switch is rated to close at approximately -0.20 in. WC (inches of water column) negative pressure, proving that the induced-draft blower is running and the venting system is clear before the control board allows ignition.

OEM vs. Generic

Pressure switches are calibrated safety devices — the trip setpoint must match your furnace exactly. Genuine OEM 11177117 is factory-calibrated to -0.20 in. WC for this model. Generic switches with the wrong setpoint can cause nuisance lockouts or, worse, allow operation under unsafe draft conditions. OEM is strongly recommended for this safety component.

Installation Difficulty

Moderate (2/5). Shut off power and gas, disconnect the two spade terminals and the rubber pressure hose, unscrew the switch, and reverse. Confirm the hose is not cracked or clogged and that the setpoint marking matches the old switch. 20–30 minutes for most technicians.
