Remove and replace light switch
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.

Check YouTube, but no one shows all the details. Need to swap hinges and spring from old retainer to new retainers by removing screw at bottom of hinge, then removing rod with small screwdriver to poke the rod out. I laid the old and new side by side and did swap to ensure proper orientation. Attach cams before sliding gasket retainer bac

k into gasket, I used a few drops of liquid soap as lubricant on the retainer to help it slide in. Very important to ensure the edge of the retainer is tucked behind the door edge or else things will not fit correctly. I did it a few times before I got it right, but didn’t break anything else.
