The Goodman 11177113 Combination Pressure Switch is a genuine OEM dual air-proving safety control for the Amana AMVC950704CXAD two-stage, high-efficiency gas furnace. This gray combination switch verifies proper draft on both the low-fire (-.30 in. WC) and high-fire (-.75 in. WC) stages before allowing the ignition sequence, protecting against blocked vents, condensate backup, and inducer failure.

Type: Combination (dual) negative-pressure switch
Setpoints: -.30 in. W.C. and -.75 in. W.C.

OEM vs. Generic

Pressure switch setpoints are calibrated to this furnace's inducer and venting design. The OEM 11177113 carries both factory-calibrated setpoints in one gray body. Generic switches with slightly different trip points can cause intermittent no-heat lockouts or, worse, allow operation under unsafe draft conditions. For a safety control, genuine OEM calibration is non-negotiable.

Install Difficulty

Moderate (3 of 5). Involves matching the hose ports correctly, transferring wiring, and confirming the switch closes on a draft test. A multimeter and manometer help verify operation. Recommended for HVAC technicians. Always shut off power and gas before servicing.
