True MFG Reach in beverage box
I have been working on a chest type True MFG beverage unit with R134A and an initial clogged condenser. Ran it all day and it maintained 35 to 40 degrees cycling on and off for 8 hours. They brought it back after a few days and said it quit cooling and had ice around the suction line right where the temp probe comes in. Today I sweated on two ports and my pressures are running about 4#'s up on the low and around 100#'s on the high. Today it cycles on and off and maintains the same temps as original. I left it running tonight to check it in the morning. I figure it is either an air flow problem, or a refrigerant problem. Any ideas?
