David T Rochester , NY June 28, 2016 Upper lights on the fridge side did not work lower lights worked fine Changed the top 2 light bulbs but that did not fix the problem. Since the switch that activates the lights still worked for the lower shelf I assumed that one or both bulb sockets were bad. Replaced both sockets and the lights worked fine. 23 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
