I have a fairly big kitchen fridge/freezer given to me years ago, so I'm guessing circa late 90's or early 00's.
I cut the divider between top and bottom, and gutted the plastic housings. It's worked great for about a year and a half, holding 11 kegs (9 taps) and running ~40° with a 2° swing, garage temps. Lately the it's running at about 52-56 and the inlet of the condenser coils has been building a blob of ice that won't go away on its own. In a normal setting this would indicate a problem for a professional, but I'm wondering if it's simply that I've taken the back of the freezer off, and now the "heat rises" function of the defrost won't get to the part that is freezing up.
Anybody know fridges and can help me diagnose? I know things happen, and as old as it is it may just be time to let 'er go, but I'd rather fix it!
