Someone brought me this refrig today and said it was not cooling. They left it and when I went to check the compressor I noted no heat on discharge line and then I noticed someone had cut something out of the refrigerant lines. When I looked up the parts diagram I realized a 3 way valve was missing. Apparently my customer thought he got a good deal on this unit and thought I could fix it. Is this valve like a thermal expansion valve. The part # listed is W10391081 but was unavailable. A little further research showed it had been replaced by W10622511. I have not seen this set up before so can anyone provide me any information on this valve and setup and whether you think this refrig can be repaired.
