Description
The Goodman B1789896 is a genuine OEM Flow Check Piston Kit designed to maintain precise refrigerant flow direction and metering in Goodman heat pump systems. Flow check pistons are a critical component in heat pump refrigerant circuits, allowing free flow in one direction while providing metering restriction in the reverse direction — ensuring efficient heating and cooling operation without the need for a separate check valve and expansion device on each circuit.

Why Replace Your Flow Check Piston?
A worn or damaged flow check piston can cause improper refrigerant metering, reduced system efficiency, and poor heating or cooling performance. Replacing the flow check piston kit with a genuine Goodman OEM part restores correct refrigerant flow characteristics and helps return the system to factory-specified operation. Always refer to the equipment service manual and verify the correct piston size for your specific unit before installation.
