The Goodman B1789888 Flow Check Piston Kit is a genuine OEM refrigerant metering device (flowrator) designed for ANZ130601AB heat pump systems. The fixed-orifice piston meters liquid refrigerant into the coil, seating in one direction for cooling and floating open for reverse (heating) flow — a key part of proper heat pump superheat and system efficiency.

Specifications

Part Type: Flow check piston / fixed-orifice metering device kit
OEM Part Number: B1789888
Compatible Model: ANZ130601AB heat pump
Brand: Goodman
Function: Bi-directional refrigerant metering (flowrator)
Includes: Piston and seal/retainer components

OEM vs. Generic

The orifice diameter on a flow check piston is matched precisely to system tonnage and refrigerant type. Installing the wrong bore size causes flooding or starving of the coil, poor capacity, and possible compressor damage. This factory-original Goodman kit carries the exact bore your ANZ130601AB requires — take the guesswork out of generic sizing charts.

Installation

Difficulty: Moderate to Advanced. The piston itself swaps in minutes once the line is open, but access requires EPA-certified refrigerant recovery, opening the connection at the metering assembly, and re-evacuation/recharge. Best performed by an HVAC professional as part of coil or line service.

An inexpensive, genuine Goodman part that has an outsized impact on system performance. Order with confidence.
