Amana-Goodman 11177105 Pressure Switch

The Amana-Goodman 11177105 Pressure Switch is a critical safety component designed for precise furnace draft inducer monitoring. As an OEM Goodman replacement part, this single-pole pressure switch ensures the venting system maintains proper static pressure before allowing the ignition sequence to proceed. Engineered to meet exact factory specifications, it eliminates the calibration issues often found with universal aftermarket alternatives. This HVAC pressure sensor is built to withstand the rigorous cycling of high-efficiency Amana and Goodman gas furnaces, providing reliable signaling to the integrated furnace control board. By accurately sensing the differential pressure created by the inducer motor, the 11177105 switch prevents the combustion process if flue obstructions or mechanical failures occur. Installing this genuine replacement ensures seamless compatibility with existing pneumatic tubing and electrical spade connectors, maintaining the system's operational integrity and sequence of operations without the risk of nuisance trips or premature failures.

Common Questions

What are the symptoms of a failing furnace pressure switch?
A faulty switch typically results in a lockout code on the control board, often indicated by three flashes, preventing the burners from igniting even if the inducer motor is running.

Can I use a universal pressure switch instead of the 11177105?
While universal switches exist, they require manual calibration. Using this OEM replacement part ensures the set point matches the manufacturer's specific safety requirements for your cabinet and blower configuration.

Does the 11177105 pressure switch include new tubing?
This product is the switch assembly itself. Contractors should inspect existing silicone tubing for cracks or moisture buildup when replacing the sensor.
