My second chest freezer died a couple of months ago. Since it was cold in my (uninsulated, no ac) garage it wasn't a big deal, but now that it is warming up the beer that it houses is now sitting at unfriendly temperatures. I have bought used numbers twice, both times $100 for a ~12 footer, one lasted around 2 years the other 3. Both developed a frozen spot on the interior (probably where a freon line busted) then stopped cooling altogether. I am now debating whether to buy another craigslist freezer or buy new. I am also wondering how to extend the lives of these things. Is there a trick?
