The water tube in my

Question

the water tube in my GE (side by side refrig) ice maker keeps freezing. When the ice tray does not get the water, it calls for more. the water ends up spraying all over the inside and freezing because the tube keeps freezing up. If I take the tube out once a day I can sometimes prevent this. I can never leave the ice maker on for extended periods of time. I have lowered the freezer temp and reduced the water feed to try and help but this has not helped.
