The Goodman OEM 11177113 Combination Pressure Switch is a genuine dual-stage draft-proving control for the AMVC950453BXAA two-stage variable-speed furnace and compatible Goodman/Amana models. This gray-bodied switch combines two negative-pressure setpoints — -0.30 in. WC and -0.75 in. WC — into a single assembly, confirming proper venting draft at both low-fire and high-fire stages before the ignition sequence is allowed to proceed. It is a critical safety interlock that prevents operation if the inducer, flue, or condensate path is blocked.

Specifications

Type: Combination (dual) negative-pressure switch
Setpoints: -0.30 in. WC (low stage) & -0.75 in. WC (high stage)
Body color: Gray
Function: Two-stage draft/vent proving safety interlock
Fits: Goodman/Amana AMVC950453BXAA and compatible two-stage furnaces

OEM vs. Generic

The OEM 11177113 is factory-calibrated to both trip points required by this furnace's staged firing logic. Generic dual switches often have loose tolerances or a single incorrect setpoint, causing intermittent lockouts that are notoriously hard to diagnose. For a dual-stage furnace, matching the exact OEM setpoints is the only reliable fix.

Installation Difficulty

Moderate. Involves disconnecting power, transferring two or more silicone tubing hoses to the correct ports (do not cross them), and moving the electrical connector. Allow 20–30 minutes and verify each hose seats fully. If unsure, use a licensed HVAC technician.
