water in refirg

i have a fridgidare frig that is over 7 years old. i noticed here recently that i am getting water on the top shelf of the frig itself. it does have an ice maker and i am thinking it is somehow tied to that but i can’t figure out how. does anyone have an idea as to what might be causing it. the ice maker seems to be working fine. is there a hose that passes through the frig to get to the freezer? i feel it is a water line issue but i can’t find any wet spots on the top of the frig just on the top and other shelfs. thanks for the help.
