We inherited our current refrigerator when we moved into our house ten years ago. The light switch never worked because it didn't mechanically engage properly with the door. So I just slapped a piece of duck tape on it and figured I'd get around to fixing it one day. But I couldn't see how replacing the switch with another one just like it would fix the problem and so I let it slide. Finally, when threatened by my wife with divorce if I didn't fix the stupid thing, I order a new switch from APP. When it arrived I could see that it was mechanically different from the old switch and was hopeful that it would fix the problem. So I popped the old switch out and the new in and...presto!...it works. It took me all of five minutes to fix. Thanks for saving my marriage! :D
