For the right side of the refrigerator door, just pulled off the old gasket and replaced it with the new one. Old gasket came off easily. Just had to pull it off. No screws on the right side. Just pushed the new one in place in the groove on the door.

For the left side, needed a Phillip’s screwdriver to remove the flap first. Helps to have a second person hold the door from moving. Once flap was off, pulled the old gasket off and installed the new one just like the right side. Then screwed the flap back on once the gasket was in the groove properly.

Initially after install, it seemed like the magnet on the door was not strong enough but after a couple of days, the magnet seems a lot stronger, sealing the air out. Very happy I replaced it. It was a lot simpler to replace than I thought it would be.

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
