Optimize refrigerant metering and system performance with the Goodman B1789882 Flow Check Piston Kit. This genuine OEM component features a precision 0.082‑inch piston (flow‑rater) that regulates refrigerant flow in condensers and ensures stable cooling performance in matched Goodman / Amana systems.
Features:
- Ideal when cooling performance is inconsistent or when there is improper superheat / subcooling indicating the metering piston may be out of spec.
- Replace during condenser service or retrofit work when the original piston is clogged, worn, or mismatched to system load.
- Used in routine maintenance or overhaul of Goodman / Amana outdoor units to preserve factory performance.
