Goodman 11177114 Pressure Switch (-.50" WC, Normally Open)

The Goodman 11177114 is a genuine OEM air pressure switch for the GMV951155DXBC 96% AFUE two-stage variable-speed gas furnace. This safety control confirms that the inducer draft motor is establishing adequate airflow before the ignition sequence begins. Calibrated to actuate at -0.50 inches of water column in a normally open configuration, it protects against blocked vents, cracked flues, or inducer failure—preventing unsafe combustion. A faulty pressure switch is one of the most frequent causes of a furnace that ignites briefly then shuts down (a common lockout fault code).

OEM vs. Generic

The OEM Goodman 11177114 is factory-calibrated to the exact -0.50" trip point required by this furnace. Generic switches with approximate set points can cause false lockouts or, worse, fail to trip on a genuine venting fault. For a safety-critical control, always choose genuine OEM.

Installation Difficulty

Moderate (2/5). Disconnect the hose and two spade terminals, transfer to the new switch, and remount—typically 15–20 minutes. Shut off power first. Confirm the -0.50" rating matches your original.

Compatible with Goodman GMV951155DXBC. Genuine OEM replacement.
