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

The Goodman 11177114 is a genuine OEM air-proving pressure switch that verifies proper draft from the inducer motor before allowing the furnace to ignite. Calibrated to a -0.50 inch WC setpoint and wired normally open (NO), it is a direct-fit safety control for the Goodman WGFM295090V5DAA two-stage variable-speed furnace. A failed or drifting switch is a common cause of no-heat, lockout, or flashing error codes tied to inadequate venting.

Specifications

OEM Part Number: 11177114

OEM vs. Generic

Pressure switches are safety-critical and setpoint-specific. Our OEM Goodman switch is factory-calibrated to the exact -.50" WC trip point your furnace's control board expects. Generic switches with approximate setpoints can cause nuisance lockouts or, worse, fail to prove draft correctly. For a combustion safety device, the genuine OEM part is the right choice.

Install Difficulty

Moderate — Involves disconnecting the tubing and wiring harness, removing mounting screws, and transferring the hose to the new switch. Confirm the correct -.50" WC rating before installing and verify operation with a manometer if available. A technician-level task; shut off power before servicing.
