Goodman 11177113 Combination Pressure Switch (-.30" / -.75" WC)

The Goodman 11177113 is a genuine OEM dual (combination) pressure switch for the GMV950704CXBB and compatible GMV95-series two-stage furnaces. It houses two setpoints — -.30" WC and -.75" WC — to independently verify low-fire and high-fire induced-draft airflow before allowing ignition. This gray-bodied switch is a critical combustion safety that prevents firing when venting is blocked or the inducer underperforms.

Specifications

Part number: 11177113
Type: Combination (dual) negative-pressure switch
Setpoints: -0.30" WC and -0.75" WC (water column)
Housing color: Gray
Function: Low-fire & high-fire draft proving safety
Fits: Goodman GMV950704CXBB and select GMV95 two-stage furnaces

OEM vs. Generic

The OEM Goodman 11177113 ships with both setpoints factory-calibrated to spec — essential for a safety component. Our generic equivalent matches the trip points and port layout at a lower cost for out-of-warranty repairs. For a combustion safety device we strongly recommend OEM to ensure calibration integrity.

Installation Difficulty: Moderate

Rated Moderate (3/5). Disconnect power, transfer the hoses to the matching ports, and swap the spade connectors. Verify draft pressures with a manometer after installation. A pressure-switch fault is often a symptom of blocked venting or a weak inducer — inspect those before replacing.

Compatible replacement safety part; professional verification of draft readings is recommended.
