I have 2, one is a 1985 and one is a 1986, back when we actually made them here. Later they came from Korea and were pretty good, newer ones are from Malaysia and China and are not.
Mine may be about 15 years old.
I was surprised at how easy it is to replace an ice-maker. A little over a hundred bucks for the new one.
On my side-by-side, unsnap supply line, 1/4” nutdriver for two blind screws, lift out, put in new one, level and tighten screws, re-snap supply—all done
