Goodman 11177114 Air Pressure Switch (-0.50" WC, Normally Open)

The Goodman 11177114 is a genuine OEM air pressure switch engineered as a direct-fit replacement for the AMVC951155DXAD two-stage variable-speed gas furnace and compatible Goodman/Amana models. It monitors combustion draft and venting to confirm safe airflow before the ignition sequence begins. A failing pressure switch is one of the most common causes of a furnace that ignites and shuts down, locks out, or fails to fire at all.

Specifications

Part number: 11177114
Set point: -0.50" WC (water column)
Switch action: Normally Open (NO)
Application: Draft / combustion air proving
Fits: AMVC951155DXAD and compatible Goodman/Amana furnaces
Type: Single-stage negative pressure switch

OEM vs. Generic

This is a factory OEM part built to Goodman's exact pressure calibration, ensuring the switch trips at the precise -0.50" WC threshold your furnace's control board expects. Generic universal switches can be recalibrated to approximate this value, but out-of-spec set points cause nuisance lockouts and, in the worst case, unsafe operation. For a two-stage variable-speed system like the AMVC951155DXAD, we strongly recommend the OEM switch.

Installation Difficulty

Easy (2/5). Replacement typically takes 15–20 minutes with basic hand tools: cut power at the breaker, disconnect the two spade terminals and the silicone tubing, unscrew the switch, and reverse the process. Always verify the tubing routing and set point before restoring power. If you are unsure, consult a licensed HVAC technician.

Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.

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. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

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

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
