Thanks everyone for the help! After reading your posts, it made me remember a few more things.1.The location of the walkin is in the kitchen area,and the compressor/chiller is on top of it(dust/dirt/heat?).2.Kegs are located right next to walkin door @46-48deg. Been after this owner for YEARSto relocate towards back of cooler.3.I remember seeing generic r-v glycol jugs (pink stuff),behind the mm glycol jugs.Could mixing the two types together affect the cooling efficiency?I took for granted that owner changed the coolant .i put my probe in the hole in top of tank(my mistake for not checkingit.) Any more ideas out there im all monitor! Thanks again-cya,BrianatKCDraftline Service.
