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.
Have had the Sears repairman come to the house to replace this part in 5 minutes for +$100.. twice. When my dad's stopped working, ordered the part and replaced it myself for the cost of the part and shipping. Use a screw driver to pry the right side of the switch and pull out. Best to watch a youtube video first. Takes about 5 minutes.
