I replaced it with a new light switch that I ordered from Appliance Parts Pros. The procedure was VERY, very, easy as there was a DIY video provided by Appliance Parts Pros which helped a great deal. I used a flat head screwdriver to pry open the old light switch from the refrigerator. Then, unplugged the wires from the switch. I plugged the wires into the new light switch and refitted it back into the refrigerator. If I had called a technician to do the job, they would've charged
$75 just to come to my house to replace a $20 part. I'm very appreciative of how helpful Appliance Parts Pros were through this process!
