The genuine Goodman 11177114 air pressure switch is a critical safety control for your AMVC950905DXAC two-stage variable-speed furnace. Rated to actuate at -.50 inches of water column (WC) and configured normally open (NO), it confirms that the induced-draft blower is producing adequate venting airflow before the control board allows the igniter and gas valve to energize — preventing unsafe combustion in a blocked flue.

Specifications

OEM Part Number: 11177114
Actuation Setpoint: -.50 in. WC
Contact Configuration: Normally Open (NO)
Stage: Pressure switch for staged/high-fire operation
Fits: Goodman & Amana AMVC950905DXAC and compatible models

OEM vs. Generic

Pressure switch setpoint tolerance is tight — an off-spec switch can cause nuisance lockouts (pressure fault flash codes) or, worse, fail to prove draft. This OEM Goodman switch is calibrated to the exact -.50" WC trip point your furnace board expects, ensuring reliable ignition sequencing. Generic substitutes often drift outside tolerance.

Installation Difficulty: Easy to Moderate

Turn off power, transfer the vacuum tubing and wiring to the new switch, and mount it in the original position. Inspect the hose for cracks or condensate blockage while you're in there — a plugged port mimics a bad switch. Test furnace startup and confirm the switch closes on a draft call.

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

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

The same physical part is often used across brand labels with different model numbers.

Should I use OEM or aftermarket for my Goodman pressure switch?
