Panasonic CS-E18NKUA Expansion Valve
A normal AC expansion valve allows the coolant to expand back to its low-pressure vapor state from a high pressure liquid state. The AC in a split system would probably blow heated air if it was deprived of a functioning expansion valve.
Clues that your Panasonic expansion valve is dead
- The air is well below the temp it should be coming out of the vents
- Your AC unit takes forever in its bid to cool as it should
