I bought a Summit Kegerator about 13 years ago for about $650. About a week ago, I noticed some of the beer in the kegs was freezing. So, I turned it down a bit and it started defrosting, and I turned it up somewhere between where it was freezing and defrosting. Then, all of a sudden today it starts defrosting again and won't go on even when I turn it all the way up.
What is the approximate life span of these things? Do I need to get a new one? Is it worth it to get it repaired?
Thanks in advance for the help.
