We inherited this fridge when we moved into a new house last year. I have fixed several problems with the fridge thanks to this website and helpful videos. The most recent issue was the water dispenser was dispensing very little water, and the ice cubes were much smaller than what they used to be. Looked up the symptoms of our issue on this website and troubleshooted the fridge in the meantime. Turns out, the only reasonable solution seemed to be replacing the water filter.
Checked the current filter on the fridge and the previous owner wrote that the filter was last changed in 2021. Ordered a new filter right away, received it within a couple of days, and installed the new filter now the water dispenses perfectly and the ice cubes are normal size!
