Additional Information

This expansion valve body (part number MJX64032401) meters refrigerant flow into the evaporator coil based on temperature and pressure conditions. It helps maintain consistent cooling performance and efficiency across operating cycles.

If your system isn't cooling evenly, shows frost on the evaporator, or has fluctuating pressures, the expansion valve may be restricted or malfunctioning. Replacing the valve restores proper refrigerant control and temperature balance.

Important: Only a qualified HVAC technician should install this part, as refrigerant must be recovered and recharged according to EPA guidelines. The system must also be leak-tested before operation.
