I have a 6 year old 36" Viking bottom mount refrigerator/freezer. Lately I have noticed that ice cream and other items were soft in the freezer. There was also ice built up on the bottom of the freezer. Ice maker has been working fine. The fan cycles on and off and all the lights are working. I called a repairman yesterday and he came out and said I had a clogged drain. He fixed that and then said he was fairly certain I had a leak in the system, but they were hard to detect. I was told to put a cup of water in the freezer and if it was frozen the next morning everything was fine. I did this and the water was frozen the next morning, but everything else seems soft. I went out today and bought two thermometers and placed one in the refrigerator and one in the freezer. The refrigerator is staying about 45 to 48 degrees and the freeezer is about 20 degrees. The repairman wants to put something called stop leak in with the freon. He seems to think I have slow freon leak. Any ideas about this.

Warning. There is mounting evidence the stop leak material will do damage to the refrigeration system. Few pro's use it, although I suspect it does stop leaks. The stuff I have is Super Seal by ACR, paid $43 for it and never used it. I have observed it is used to repair leaks in HVAC equipment like heat pumps. If your technician put pressure gages on the compressor and observed a vacumm, your compressor is probably damaged (Due to moisture ingestion) and must be replaced. This assumes a evaporator leak (most are). Also, the evaporator seals may be so damaged that the sealant will not work, or it will work, but the seal leak will get worse later. If no vacumm, a super seal can be used, but the system must be purged of all refrigerant plus contaminents, a new dryer installed and the system re-charged. All this would cost about $200 with no real guarantee the system will not fail later. Probably not worth the effort and cost. The system MUST be purged of all contaminents because addition of super seal would react with any moisture and seal up critical areas like the capillary line! For an expensive refrigerator like this, it deserves a better repair effort. A pro would verify where the leak is with flourescent dye, and probably never use super seal. Lacking specific technician data, Your refrigerator may be frozen up, have a bad compressor, or have a cloged condenser in the back of fridg and not have a refrigerant leak.
