I have an Adler Barbour cold machine. Had a technician over to refill the r-134 (I'm still a novice on refrigeration systems), and there is inconsistent flow through the evaporator, indicating a partial block. Sometimes you hear the refrigerant gurgling through, but most times not. It is not cooling. I suggested replacing just the evaporator, but he said the whole unit would have to be replaced. Anyone have any thoughts or opinions on this? Even if I could replace just the evaporator, does it make sense to attach to an old compressor, or better to bite the bullet, and replace the whole unit?

Re: Refrigeration
If the tech did not pull a vacuum on the system of at least 30 minutes before filling, you may have water freezing to ice and blocking the refrigerant flow.

Re: Refrigeration
Thanks Terry,
I assume water got in from the atmosphere when the tubing was originally connected? If so, how does one remove said water? I guess the 30 minute vacuum would do the trick. Adler Barbour now uses quick connect type couplings, I assume to reduce this from happening.

As information, I did choose to buy a new Adler Barbour cold machine - air cooled - about $1200 from Defender. I also searched down the original gasket for the top loading ice boxes. It can be purchased from McMaster Carr - item no:
