Amana-Goodman 10727923 Pressure Switch

The Amana-Goodman 10727923 Pressure Switch is a critical safety component designed for specific high-efficiency furnace applications. This SPST (Single Pole Single Throw) vacuum switch is factory-calibrated to a -0.70" WC (Water Column) set point, ensuring precise monitoring of the inducer motor's draft performance. It features a standard 1/4" barb connection for secure pneumatic tubing attachment and utilizes the Amana Goodman 10727923 design to communicate directly with the integrated furnace control board. When the draft inducer reaches the required negative pressure, the -0.70" WC pressure switch closes its internal contacts, allowing the ignition sequence to proceed. As an OEM HVAC replacement part, it ensures proper fitment and maintains the original equipment’s narrow operating tolerances. This furnace pressure switch replacement is essential for resolving Goodman pressure switch error codes caused by diaphragm failure or contact sticking, preventing unsafe combustion cycles in residential systems.

• Precise Calibration: Fixed -0.70" WC set point prevents nuisance tripping while ensuring safe venting and combustion.
• Reliable Switching: SPST configuration provides a clean signal to the control board to verify draft induction.
• OEM Standards: Genuine Amana-Goodman 10727923 replacement ensures compatibility with specified furnace models.
• Standard Connection: The 1/4" barb allows for a direct fit to existing vacuum hoses without modifications.

What causes a -0.70" WC pressure switch to fail?
Failures typically stem from a ruptured internal diaphragm, moisture buildup in the vacuum lines, or pitted electrical contacts within the SPST housing.

Is this switch compatible with 80% and 90%+ AFUE furnaces?
This specific 10727923 pressure switch must be matched to the exact rating on your existing component. It is designed for specific furnace blowers requiring a -0.70" WC negative pressure threshold.

How do I verify if my pressure switch is faulty?
Technicians should use a manometer to verify the inducer is pulling at least -0.70" WC and a multimeter to check for continuity across the 1/4" terminals when the set point is reached.
