I only joined the forum to actually a few months ago but have been here reading for years. You've saved me $1000's on my out of warranty stuff where you identified the broken part that I then bought myself using link here and then replaced myself. Thank YOU.
Needless to say, the loud water flow is still there. It appears so far that the ice maker water line freezing is fixed by W11087201, the fill tube heater part. Will ask him to replace filter housing with W11482384. It's loud throughout the whole path, from filter to ice maker and water dispenser. I'm under warranty and have good relationship with this guy so any other parts you can think of that might cause loud water?
Finally, after a couple delays and one broken part, I got the Water Filter Housing: W11482384 installed today. Unfortunately, no change to the loud water lines. He agreed it's air somehow getting in but it must be after the filter housing. It's easily heard form within the box where the filter is so something in there maybe. Any ideas for where air could get into the line after the filter housing?
