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.

After watching a few iTunes videos I was able to order the light switch from part select and within a week I had the new switch. I had a little trouble getting the switch out. I used a flat screw driver and taped around the edge to keep from damaging the wall inside. I found the clip on the right side and had to use some force to get it popped out, you may need to use pliers to disconnect the switch.

Cover the putty knife with tape so you do not scratch the side wall where the switch is located. Slide the knife under the edge of the switch and push in a bit towards the switch and slightly twist to pop the switch out of its hole. Disconnect the wires from the switch and simply plug in the new switch. Push wiring back into the hole and careful push the switch into the hole until it snaps into place.

Go to this site on You Tube to watch the "how to" replace the gasket retainer. The retainer I needed did not come with brackets or the cam you will need. You will need transfer them from the old retainer to the new one. Not hard, just be mindful of position of the items you remove to put them back in place the same way. A metal rod holds the brackets and spring in place with a screw on one end to prevent rod from sliding off retainer. The cam has a screw that holds it in place, use from old retainer. If the old cam is not broken use the one from the old retainer. It is not hard and you will save $$$ that you would pay an appliance repair company.

the light did not work when door was opened. At first it would flicker then off completely.

Remove door seal and cam shaft (one piece). Remove broken cam by removing Philips head screw. Replace broken cam with new cam and reassemble. The actual repair took about 15 minutes however the majority of time was spent figuring out that the door seal and cam shaft had to be removed, no tools required.
