There was a 1/1/21 posting on Cheapo Refrigeration by Nelly about using the guts from a dorm refrigerator to convert your icebox (search the Archives if you're interested). I'd been thinking about doing this ever since I'd seen Barry Olsen's Photo Forum posting a couple of years ago (see related link). Nelly's posting gave me the impetus to finally do it. It works! It was a bit more work than I planned, but a lot of that had to do with working out how to fit everything in without kinking or breaking the lines. All I have left to do is to finalize the wiring. Right now I just have it plugged in to an extension cord for testing. Some hints: 1. Most of the newer models (like mine, which was from Home Depot) have the coils that dissipate the heat imbedded under the skin of the refrigerator. This means that you need to be very careful in tearing the thing apart since you can't tell where they are. If you have to cut the skin, be very careful, one nick and you're done for. 2. The internal coils also take up more room and are a bit more unwieldy than the external ones so try to find one with external cooling coils. If you get one with internal coils, understand that they cover the same surface area as the sides and top of the refrigerator so make sure you have room for them. The external ones are also a bit less fragile since they have a heat-dissipating grid attached to them. I used aluminum tape in mounting mine (the internal kind) to give them a bit more surface area. I lucked out in that they just fit perfectly around the galley drawer unit in my Catalina 30, which is right next to my icebox. The compressor went in under the drawer unit. 3. Make sure that the evaporator (the thing that cools) is big enough but not too big since you have to cut a hole big enough in the side of your icebox to fit it in. 4. Buy one that looks like it has enough distance from the compressor to the evaporator to fit your situation. If not, you might not have enough tubing between the compressor and the evaporator to fit your situation. 5. Try to figure everything out ahead of time and install it just once. The more you manipulate things and/or take it in and out, the greater the chance of kinking or breaking a tube.
