Description
The Amana-Goodman B1789855 Flow Check Piston Kit is a metering assembly component in cooling and heating equipment within HVAC systems. It regulates refrigerant flow inside the system by controlling pressure balance and directing movement through the coil circuit. The piston assembly is typically applied in air handling and condenser units where consistent refrigerant distribution is required for stable operation. It supports proper heat exchange by maintaining calculated flow conditions across the evaporator coil helping the system manage temperature transfer efficiently during cooling or heating cycles in residential and light commercial equipment.
