The door on my dad's fridge door fell off last year. To hear my niece tell the story, it "almost killed her", but then, she's a teenager and may have a flair for the dramatic. He had no choice but to buy a new door, and he installed it with the retro-fit kit.
So as a bit of cheap insurance, I went ahead and bought the retro-fit kit off Amazon and put it on my fridge last month.
I consulted my dad for some details on installation, even though it was dead simple. One thing we noted was the difference in weight between his door and mine. Same fridge, just mine was manufactured more recently. My door (once removed) could be lifted easily with a few fingers on one hand. My dad said "it took two men and a boy" to lift his into place to install the new door (again, with the drama). So, perhaps this is partly the issue? Both of ours have wood panel inserts on the front, but I have no explanation as to why his door was so much heavier than mine.
