Does the pipe(that fills the ice tray) heater plug into this part - AP4136070? If there is no power going to the heater is this part bad?
The heater DA47-00110C is the heater that wraps around the tube for the icemaker fill. If this is not getting power then it would need to be replaced.
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.
