Today while I was installing the new frig fan, I noticed water draining down the front of the cabinet. After sopping and mopping, I discovered the drain was overflowing down the back of the frig inside. Must be clogged, so I went looking for something to run down the narrow hole. I tried a 12" cable tie, but it didn't clear it. I was afraid to stick anything too rigid thru there, and then I happened to find a length of silicone aquarium tubing. It fit in nicely and with a short puff of air, the clog was gone.
And the frig fan installs in minutes and works GREAT!
