Amana-Goodman 11177117 Pressure Switch

The Amana-Goodman 11177117 Pressure Switch is a critical OEM replacement part engineered for high-efficiency furnace and heat pump applications. As a veteran technician knows, maintaining the specific 0.20" WC setpoint is non-negotiable for ensuring the induced draft blower is moving the correct volume of air before ignition. This factory-authorized component is designed to replace failing or intermittent switches in Amana and Goodman gas furnaces, providing a precise safety interlock that prevents operation under hazardous venting conditions. Built for durability in residential and light commercial environments, the 11177117 ensures your equipment meets original factory specifications for vacuum and pressure monitoring. Using a genuine 11177117 pressure switch eliminates the reliability issues common with universal aftermarket parts, ensuring proper terminal alignment and mounting hole compatibility for a fast, accurate install on the job site.

Common Questions

What are the symptoms of a failing 11177117 pressure switch?
Common indicators include the furnace inducer motor running without the burners igniting, or a specific flash code on the control board (often 3 flashes) indicating the pressure switch failed to close or stayed open during the startup sequence.

Can I use a universal pressure switch to replace the 11177117?
While universal switches exist, it is highly recommended to use the 11177117 OEM part. The 0.20" WC rating is specific to the heat exchanger resistance of your unit; using an incorrect rating can lead to unsafe operation or frequent system lockouts.

Why is my inducer running but the pressure switch is not closing?
This can be caused by a faulty switch, but check for cracked pressure switch tubing, a restricted flue, or a failing inducer motor before replacing the 11177117. Ensure the sensing port on the collector box is clear of debris.
