You can look up your fridge model for specific details. In my fridge, the ice maker can be pulled out and removed. This makes it easy to replace. Pulling out the ice maker and waiting for all components to thaw and water/ice to clear can also fix a good portion of issues. A similar comment could be made for the freezer in general. Unplugging the freezer and let it thaw out for 1-2 days every few years can help preserve the life of many components, as well as improve efficiency, reducing electric bill. My fridge/freezer is ~20 years old and has only had one part that needed to be replaced during that period, in spite of being a brand/model that is not known for good reliability.
However, I pulled my ice maker out for a different reason. It’s a waste of space that I don’t use, which is more prone to fail than other portions of the fridge. Removing my ice maker adds as much space in my freezer as an extra shelve. Unfortunately, I still have to deal with the hole for ice cubes. I filled the hole with a small microfiber cloth, which seems to prevent the condensation-related leaks.
I don’t see the big appeal of adding ice to beverages. Not drinking cocktails/alcohol may contribute. Room or fridge (not freezer) temperature is fine for the beverages I do drink. I’d also prefer to not dilute the beverages with water, as the ice melts.
