Thanks Roy, I really appreciate the help. I bought the compressor from Applied, so they'll most likely
provide a replacement. Finally found the old expansion valve this morning,
so when I get back might try putting it back in first. I only took it out because "your supposed to".
While it's not too likely I got two defective brand new expansion valves in a row, it is possible.
Too bad I'm out of refrigerant or I'd try it now.

I think I'll also switch to real Duracool though it's more expensive. I'm suspicious of the murky green color in the oil,
but can't figure out what it could be other than dye. While my understanding that Enviro-Safe is equivalent, I suspect they've
changed their formula (I ordered Glacier Gold originally, but Enviro-Safe is what they sent for whatever reason).

thanks again,

Karen
