Video makes it look easy. Kenmore refrigerator does not have "groove" along the right hand side of switch that allows for pushing down on release. Used a thin screwdriver to get under to push while holding switch edge with pliers. Kept slipping. Tape sides to avoid scratching inside of refrigerator.
Shut off water supply. Disconnect main supply line. Remove rear lower panel on back of refrigerator. Remove all tubing clamps on back. Disconnect leaking tubing from water supply valve. Remove water filter and unscrew/remove water filter housing. Replace tubing - connect to water filter housing then to water supply valve. Reconnect filter housing and filter. Reinstall lower panel, then main water supply line, then all tubing clamps. Turn water back on and check for leaks after discarding several glasses of water to fill filter. Job complete!
The heavy work is moving the fridge, then take off the lower plans. Use a bowel or cup for screws and the water line connector spacers so you don't loos them. undo connections holding water line, including the bottom brakes for the solenoid. Reuse the spring around the lower waterline to prevent external wear on the line.
NOTE: remove the waterline connector spacers and save! NOTE: you must compress (not pull) the connect to then pull the waterline out of the connectors. NOTE: You must also remove the water filter and housing inside the fridge but this is easy. MOTE: Test the line for leaks by turning on the water and then using the door water. The filter will need to refill so it may take a minute before water comes up. This line only have pressure when the door water is used or the ice maker needs to make ice.
After replacing the line, test the line for leaks by using the door water so the solenoid fills the lines
