The Goodman 11177113 Combination Pressure Switch is a genuine OEM two-stage draft-proving control for the AMVC950453BXAC variable-speed condensing furnace. This gray dual-switch assembly combines two set points — -0.30" W.C. and -0.75" W.C. — into a single body, proving adequate inducer draft on both the low-fire and high-fire stages before the ignition sequence is allowed to continue. If venting is blocked, the condensate trap is clogged, or the inducer is weak, the switch keeps its contacts open and locks out the burners for safety.

Set points: -0.30" W.C. and -0.75" W.C. (dual/combination)
Function: Two-stage draft / vacuum proving switch
Body color: Gray, dual-port
Fits: Goodman/Amana AMVC950453BXAC two-stage furnace
Type: Genuine OEM replacement

OEM vs. Generic

Because this control governs both firing stages, the calibrated set points must match the AMVC950453BXAC exactly. The OEM Goodman switch is factory-set to -0.30"/-0.75" W.C.; a generic single or mis-rated switch will cause nuisance lockouts or fail to prove draft correctly. For a combination two-stage switch, OEM is essential.

Installation Difficulty

Moderate (3/5). Disconnect power, label and transfer the wiring harness and the two silicone tubing ports to the matching fittings, and mount with the original screws. Confirm both stages prove draft on a test cycle after installation.
