Genuine Goodman 11177114 Pressure Switch (-0.50" WC, NO)

The Goodman 11177114 is an OEM negative-air-pressure switch for the AMVC950905DXBA variable-speed, 96% AFUE furnace. This normally-open switch proves that the induced-draft blower is establishing adequate negative pressure before the control board allows ignition. If venting is blocked or the inducer is weak, the switch stays open and locks out the burner — a core safety function that prevents combustion without proper draft.

OEM vs. Generic

Pressure switches must trip at an exact setpoint. The OEM -0.50" WC switch is calibrated to this furnace's inducer and vent design; a generic switch with a different setpoint can allow unsafe ignition or cause false lockouts. For a safety component, insist on OEM.

Install Difficulty

Easy–Moderate (2/5) — remove power, transfer the two spade wires and the sensing hose to the new switch, and mount. Verify no cracks in the tubing on restart.

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?
