The Goodman 11177113 Combination Pressure Switch is a genuine OEM dual-stage air-proving switch for the Goodman/Amana AMV90453BXAB two-stage gas furnace. This gray combination switch integrates two independent set points — -0.30 in. WC and -0.75 in. WC — to confirm proper draft on both the low-fire and high-fire stages before the control board allows ignition. If adequate negative pressure (draft) is not proven, the switch keeps the gas valve closed, protecting against blocked flue, failed inducer, or venting problems.

Genuine OEM Goodman/Amana part number 11177113
Combination dual switch: -0.30 in. WC and -0.75 in. WC set points
Two-stage furnace draft-proving safety control
Gray housing, factory-calibrated diaphragms
Direct fit for AMV90453BXAB and compatible two-stage models

OEM vs. Generic: The OEM combination switch is factory-calibrated to Goodman's exact trip points for both stages, so low- and high-fire draft are proven correctly. Generic single-pressure substitutes often can't match the dual set points and can cause pressure-switch lockout faults or unsafe firing. OEM is the reliable choice for this safety-critical control.

Install difficulty: Moderate. Replacement involves disconnecting two low-voltage wire harnesses and two rubber hose ports, then remounting the switch — typically 20–30 minutes. Match each hose and connector to its original port, and verify operation with a manometer after install. Always cut power before service.

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