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.
