The video showed this to be an easy fix. Turned out to be fairly difficult level 4 of 5. I tried to do it myself as the video showed it to be very easy. There was no way I could do it. Had to ask my electrician, next-door neighbor, to help me with it as I could not do it myself. He had considerable difficulty removing the old switch from the refrigerator, just inside the door.
The video is really not accurate as far as difficulty.
With my neighbor John's help the repair was completed successfully and the refrigerator light comes on correctly when the door is opened.
