Part #6600JB1010A
The interior light in your refrigerator is controlled by a switch that is activated when the door is opened and closed. If your refrigerator light will not turn on, or stays on when the door is closed, you could have a faulty switch. The switch is spring-loaded and is a generally closed type of switch meaning there should be no continuity when the button is pushed, and continuity through the switch when it is no longer engaged. This plastic, white, OEM switch is sourced directly from the manufacturer, is sold individually and is easy to replace. The repair usually takes less than 15 minutes and requires a flat-blade screwdriver and needle-nose pliers.

This part is a replacement light socket for your refrigerator. This model is white in color, and it has two sockets that will fit two separate light bulbs. The light socket connects to the power source, and the light bulb is screwed into it. If the light in your refrigerator is not working when you open the door, you could have a faulty socket.

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.
