I put the model number for our Kenmore refrigerator in a search for an interior light switch on the AppliancePartsPros.com site. A specific part appeared. Then I did a search on installation of the part. A video appeared that showed me how to replace the part...nothing complicated. The part was ordered and when it arrived, I disconnected the power to the refrigerator. The old switch was removed and the new one was in about 5-10 min. When the power was restored, the light came on and then went off when the door opened and closed. Nothing very complicated.
