Thanks for the run down HandyGirl. I woke up today and had water on my kitchen floor. I located the problem, ie the drain hole, but my first inclination was that it had frozen, after thawing and poking and pouring hot water down it, I realized that it was probably clogged. I googled our frigerator, and came across your answer. It provided exactly what I needed/wanted to know and now its all good. Thanks!
PS For the next guy or gal, the back two "legs" of the frige are wheels, so to move it, just pick up the front and push/pull.
