The Goodman 11177113 Combination Pressure Switch is a genuine OEM dual-stage air-proving safety switch built for the AMVC950704CXBA two-stage variable-speed furnace and compatible Goodman/Amana models. This gray-bodied switch combines two trip points — -0.30" WC and -0.75" WC — to verify proper draft and venting on both low-fire and high-fire operation before allowing ignition. If adequate negative pressure isn't sensed, the switch prevents the furnace from firing, protecting against blocked vents and unsafe combustion.

Specifications

Type: Combination (two-stage) negative air pressure switch
Setpoints: -0.30" WC and -0.75" WC
Color code: Gray
Function: Draft/vent proving safety interlock
Fits: AMVC950704CXBA and compatible Goodman/Amana furnaces
OEM Part Number: 11177113

OEM vs. Generic

The genuine OEM 11177113 is factory-calibrated to the exact trip pressures required for both firing stages. Generic switches with mismatched setpoints can cause nuisance lockouts, failure to reach high-fire, or bypass a genuine venting fault. On a safety-critical draft-proving control, OEM calibration is essential.

Installation Difficulty

Moderate — Replacement involves disconnecting power, unplugging the wiring harness, transferring the pressure tubing to the correct ports, and remounting the switch. Correct tube routing is important. A qualified HVAC technician should verify both stages prove properly after installation.

Restore safe, reliable two-stage operation with a genuine Goodman OEM pressure switch.
