Amana-Goodman 11177114 Dual Pressure Switch

The Goodman 11177114 pressure switch is a genuine OEM safety component used in many Goodman and Amana furnaces. It monitors combustion air pressure (vacuum) across the inducer motor and venting system to ensure safe furnace operation. Should the airflow fall outside acceptable thresholds (e.g. due to blockages, inducer failure, or hose leaks), this switch helps prevent the furnace from firing in unsafe conditions. This 11177114 model is coded for a ‑0.50″ W.C. setpoint and is classified as a “normally open” (N.O.) switch—meaning it closes only when the target vacuum is achieved.
