Thin, flexible edge on outermost door gasket was tearing from the main gasket, likely due to being rubbed when accessing refrigerator..
Gasket is held in place by an extrusion on the back side. Simply remove the old gasket and press the new gasket's extrusion into the track on the door.
Refrigerator wasn't "winterized" ..This is a summer home, the cold winter cracked the water valve
I put the new unit up to the old one to see exactly how it goes, took the 2 screws holding the unt off...Took the 3 water lines off with adjustable wrench, put back exactly the same way and it worked with no leaks
Following previous installation instructions was very useful. Would add that the nut driver needs to be 1/4 in and to release the water lines from the valve body, simply squeeze the blue ring toward the valve and pull on the water lines at the same time. Simple fix!
Repair was easy. Unplug refrigerator, turn off water to ice maker, remove back panel, disconnect water inlet valve, disconnect water supplies and electrical connections. Cut ends off tubing to modify to new part connections, connect tubing, connect electrical supplies, reinstall back panel, plug refrigerator in, turn water supply back on. We made sure that there was no ice build up in the supply tube into the ice maker and made sure that everything worked correctly before putting it all back together. It was an easy repair.
We had someone to come and look at it and we were told it was the solenoid valve. The repairman unstuck it for us and said when it does it again, he would have to order the part. We took it upon ourselves to order the part and DIY. We replaced the part that we were told was the problem and "guess what" it's still not fixed. It's still shooting out crushed ice. Will have to call repair guy back out here to see what we did wrong.
I read other suggestions trying isolate auger motor shaft with pliers while turning bar drive. needle nose pliers could hold the shaft. bar drive just would spin. so took the whole ice box assembly out (only 2 screws) and with a metal cutting blade used the sawzall to cut along the shaft. freed it up enough to then unscrew it from that point. Left handed threads by the way.
