On December 31, 2015, our refrigerator quit. I called a repairman, but of course he was away for the weekend. I probably should have consulted YouTube, but it just seemed like the thing to do to call for help this time. He actually didn't charge much - $60. Plus the cost of the motherboard for the refrigerator. Over $200 (including the tax).
I used the back room as a walk-in refrigerator. Since there is a locked carport outside its door, I left the door open to cool the room. It worked pretty well, but mice (or rats) got in and found the cheese and a few other things.
*sigh* It's running now. Freezer freezes. Nothing in it, since I had to throw out everything that had been there. The fan to blow the cold air into the refrigerator isn't working, though.
Edited 6/11/18 to add: The sensor in the freezer doesn't work, and I've continued to live with it that way. Both the frige and freezer sides now are barely cool on the top shelf and very cold at the bottom. It's actually quite useful - I store grains and nuts in the barely-cool top of the freezer and frozen vegetables at the bottom. In the fridge, the top shelf is room temperature, while the bottom drawer does an almost-freeze on meats.
