The Goodman 11177113 Combination Pressure Switch is a genuine OEM dual-stage air-proving safety control for the Amana/Goodman AMVC950453BXAB two-stage variable-speed furnace. This gray combination switch integrates two set points — -.30 in. w.c. and -.75 in. w.c. — into a single body to confirm proper draft on both low-fire and high-fire stages before the ignition sequence is allowed to proceed.

The pressure switch senses inducer draft and proves the flue is clear and the combustion air path is open. If the switch fails to close (or opens during a call for heat), the control board locks out the burners to prevent unsafe operation — a common cause of no-heat and flashing error codes.

Type: Combination (two-stage) negative-pressure switch
Trip points: -.30 in. w.c. and -.75 in. w.c.
Color: Gray
Part number: 11177113
Fits: AMVC950453BXAB and compatible two-stage AMVC95 furnaces

OEM vs. Generic: Genuine 11177113 is calibrated to the exact factory set points and hose-port configuration of the AMVC95 inducer. Generic switches often use single set points or different actuation pressures, which can cause nuisance lockouts or defeat a critical safety function. Choose OEM for safety controls.

Install difficulty: Easy to moderate. Disconnect power, transfer the sensing hoses and wiring to the new switch, and mount it. Verify draft readings after replacement. A basic multimeter and manometer check is recommended.
