Description
The Amana-Goodman B1789849 Flow Check Piston is a refrigerant metering component used to regulate the flow of refrigerant through the evaporator circuit. It is installed inside the flow check orifice assembly of air conditioning and heat pump units, where it supports maintaining controlled pressure and proper phase change of the refrigerant as it moves in HVAC systems applications. It is used in residential and light commercial condensers and heat pumps, where it ensures stable cooling performance in the system. It operates as part of the metering system that supports consistent heat exchange efficiency and accurate operation of the refrigeration cycle.
