I have a 1.5 year old Whirlpool French Door fridge with the extra fridge drawer (model WRX735SDBM). A week or so ago the water dispenser stream seemed to narrow a bit, but it went back to normal within a couple hours. Suddenly just now, it gave a few dribbles then stopped completely. The unit makes noise like it is dispensing, and the ounce numbers go up as if it were, but nothing comes out. The ice is coming out fine, but there is a decent amount in the tray, so I can't tell yet if water is going to the ice maker. (However, I did just hear it run like it does when it fills with water and it was not as loud as normal so I wonder if the water is not moving through the line...)

I will say, when I went to check the tray, it seemed frozen shut. So I left the door open a few minutes and was then able to open it. Could the water line INSIDE the fridge be frozen? OR, the supply line for the fridge goes through our garage and though it is boxed in with drywall, I don't think it's insulated (was boxed in when we moved, so never looked deeper). It did freeze a few years ago and spew all over the garage and we are in NY and going through very low temps. In case it is that garage line, should I turn it of at the valve in case of freeze, and try it again in a few days when things warm up? Or I was reading about people using hair dryers to melt internal freezing, but I have no clue where to direct that heat? On the door behind the dispenser maybe?
