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.
