Ice maker freezing up (by 3 users)

If it is only the fill tube that is freezing up, or getting full of ice, than your water valve is leaking (letting drops of water thru to your ice maker and filling the icemaker fill tube up and freezing). If this is the case, replace the dual water valve (part # 1071263) located in the back of the refrigerator, just follow the water line from your wall into the refrigerator. Make sure you turn off the water to the refrigerator and also unplug it. The dual water valve is the one that has two water lines, one going to the icemaker and one going to the water dispenser. On this model, I think you only have one water valve. On some you have two, the primary water valve and a secondary water valve (the dual valve). If this is your case, I would highly recommend you replace both. As far as the Refrigerator side freezing things up, I think that is a whole different issue. Please post back.
