Whirlpool side-by-side model number wrs325fdamO2 flickering lights. Customer complaint was all lights on both sides were barely flickering for a period of time before they would come on if at all. After some research I found that there is one master light and the rest of the lights are considered slaves. Master Light for this unit is part number wpw10515058. I replace the master light which is located in the ceiling of the fresh food side and all lights are now working. Problem solved. Hope this helps someone.
