The Goodman 11177113 Combination Pressure Switch is a genuine OEM replacement engineered for the Amana/Goodman AMVC950453BXAD variable-speed modulating 95% AFUE gas furnace. This dual-function switch monitors both the low- and high-fire draft states of the inducer, proving safe venting before the ignition sequence can proceed. If your furnace locks out, short-cycles, or throws a pressure-switch fault code, a failed or drifting switch is a common culprit.

Specifications

Type: Combination (dual) negative-pressure switch
Set points: -.30 in. W.C. and -.75 in. W.C.
Body color: Gray
Function: Inducer draft / combustion airflow proving
OEM Part Number: 11177113
Fits: AMVC950453BXAD and compatible AMVC95 series furnaces

OEM vs. Generic

This is a genuine OEM Goodman/Amana switch with factory-calibrated trip points and the exact port and terminal configuration for your furnace. Generic or universal switches often ship with a single set point or mismatched pressure calibration, which can cause nuisance lockouts or bypass a critical safety. For a modulating furnace, matching both set points is essential to correct low/high-fire operation.

Installation Difficulty

Moderate — a competent DIYer can complete the swap in 15–30 minutes with basic hand tools. Disconnect power at the breaker, photograph the tubing and wire routing, transfer the hoses to the matching ports, and reconnect the spade terminals. If you are uncomfortable working around gas appliances, have a licensed HVAC technician perform the replacement.
