Goodman 11177113 Combination Pressure Switch

The Goodman 11177113 is a genuine OEM dual-stage combination pressure switch engineered for the AMV90704CXBA variable-speed condensing gas furnace and compatible Amana/Goodman 90%+ AFUE models. This gray-bodied switch monitors both low-fire and high-fire venting draft, proving safe combustion airflow before the ignition sequence is allowed to proceed. If venting becomes blocked or the inducer fails, the switch opens and locks out the burner to protect your home.

Specifications

Type: Combination (two-stage) negative-pressure switch
Setpoints: -.30" WC and -.75" WC
Color: Gray
Configuration: Normally open, closes on draft
OEM Part Number: 11177113

OEM vs. Generic

Our Genuine OEM 11177113 is factory-calibrated to the exact -.30"/-.75" trip points your furnace's control board expects, ensuring reliable staging and safe operation. Lower-cost generic switches often carry approximate setpoints that can cause nuisance lockouts or delayed ignition. For a combustion-safety component, we recommend the OEM part.

Installation Difficulty

Intermediate. Replacement involves shutting off gas and power, transferring the vinyl sensing tubes to the matching ports, and swapping the electrical spade connectors. Most handy homeowners complete it in 20–30 minutes, but if you are unsure about draft-proving diagnostics we recommend a licensed HVAC technician.
