a new evaporator.

If the blockage is coming from frozen moisture you may be able to
cure it by leaving a vacuum pump on the system for 6 to 8 hours. I
just had to do that with a new Adler-Barbour system and it seems to be
OK now. The symptoms were that it would start out cooling just fine
on startup and then slowly degrade over 24 hours.




Or, alternately, purge the system with dry nitrogen, then vacuum pump.
