On the inside back wall of the refrig at the ice maker area water apparently drips down and accumulates at fan and makes loud noises because it freezes there. I replaced the solenoid, maybe looking replacing the heater fill tube. What do you think?
Check the fill cup on the icemaker to make sure that there is no ice that is accumulating in it as this would be the most likely cause for this issue. Ice collecting in the fill cup can make it overflow and also cause it to drip down.
