Big ice user here! We have a fridge w/ ice maker & door dispenser of ice. About every month we have to get in there and break up what essentially is an ice dam in the components. I don’t know if it’s the water line creating it or just condensation from the water line that then freezes but once we break that up, it starts making ice again. My H youtubed how to fix it the first time it stopped working to identify all the different issues it could be and this was it. I’m sure there’s a more professional fix that could be done for $$$ but we’ll stick with our DIY.
