I had a 22 cu ft Amana side by side, stainless panels, ice & water in the door, etc. At the 11 or 12 year (or so) mark it I noticed the freezer wasn't as cold as it should be. A friend came by to check it, determined it was a little low on freon and recharged it.
This lasted 4 - 5 months and it wasn't staying as cold again. It had a leak and the 2nd time he added a die to help find the leak. Long story short, the evaporator core inside the fridge was the source of the leak and due to time (had to remove the all of the panels inside of the fridge to get to it) and cost (it was well over $1000 just for parts) I decided to "throw it away" and get a new fridge, as much as I hated to do so.
The new one is a Samsung (ugh) french-door with ice & water, bottom freezer model. Honestly I could care less about the "french door" thing and only see problems with the seals down the road. But Samsung had been making the bottom freezer models for GE for 2 1/2 years before I bought this one and so far I've been very happy with it the last 2+ (3?) years I've had it.
