Nordyne MS3BC030KA Expansion Valve
An expansion valve allows the coolant to spread back into vaporous form from a high-pressure liquid form. The AC in a split system would be worthless if the valve was missing.
Major warnings your refrigerant expansion valve should be replaced
- AC unit takes a long time in its bid to cool the indoors
- Cooled air is much warmer than it really should be blowing through the ductwork
