Goodman 11177113 Combination Pressure Switch

The Goodman 11177113 is a genuine OEM dual-stage combination pressure switch engineered for the WGFM295070V4CAB two-stage gas furnace and compatible Goodman/Amana models. This switch monitors both the low-fire (-.30 in. WC) and high-fire (-.75 in. WC) draft conditions, verifying that the induced-draft blower is producing adequate venting before and during each firing stage. If flue draft is blocked or weak, the switch opens the ignition circuit to prevent unsafe combustion and lock out the furnace.

Specifications

Type: Combination (dual) negative-pressure switch
Trip points: -.30 in. WC and -.75 in. WC
Color code: Gray body
Application: Two-stage induced-draft gas furnaces
Fit: WGFM295070V4CAB and cross-compatible Goodman/Amana units
Connections: Standard 1/4 in. spade terminals with hose ports

OEM vs. Generic

This is the factory OEM part — calibrated to Goodman's exact trip pressures and terminal layout, so it drops in without adapters or recalibration. Aftermarket universal switches may use approximate set points that cause nuisance lockouts or fail to trip on genuine draft faults. For a safety-critical component, OEM is the reliable choice.

Installation Difficulty

Moderate — Roughly 20–30 minutes. Requires disconnecting furnace power, labeling and transferring wire terminals, and reseating the pressure hoses on the correct ports. Best performed by an HVAC technician; verify tubing routing and confirm proper trip on both stages after install.

Always shut off electrical power and gas before servicing. Professional installation recommended.

How do I replace the pressure switch on my Goodman WGFM295070V4CAB — 11177113?

Difficulty: Medium (20–30 min)
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.

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