Be careful. (this is not your problem currently) but I know someone who left for a weeks vacation and came back to a flooded house due to the little plastic hose to the fridge. I would upgrade to one of those braided stainless steel hoses if I were you.So when I push the lever for water to come out of my fridge it doesn't work. I thought possibly the waterline in the back had a kink. Pulled it out and it was fine.
I also emptied the ice maker to see if the refrigerator wasn't getting any water to make ice either. The next day I opened it and it was full again.
Any ideas what the issue may be?
