We’re likely in a similar boat, due to the size of our fridge nook. We had the LG 530L French Door Fridge Stainless Steel GF-B505PL previously, that the compressor failed in.
I’d you aren’t already, you should be pulling the fridge out every six months or so and cleaning behind it to keep the compressor free from dust bunnies.
We managed to just squeeze in a Hitachi 638L 4 Door French Door Fridge in the same space, even though it juts out by ~10cm - the added 100L capacity (and bonus unplumbed ice maker) was worth the trade-off.
Yeah, that’s basically it - there’s a small removable filter/container in between the two vegetable drawers that you fill up with water.
It then pumps the water into an ice tray in the freezer, and dispenses ice into a tray every few hours.
