Water keeps freezing in the ice tray water supply tube preventing ice from being made. Do I need a heater? If so how do I replace it?
The water fill tube for the icemaker has a heater on it which is part number DA97-04501S. It is a low wattage heater and you will want to check voltage to it to make sure that it is getting power. If it is then replace the tube. There is a cover at the top that will allow access to the tube.
