The lights and led display of my whirlpool side by side fridge freezer, on the fridge side only, have stopped working. My wife heard a pop. After checking light bulbs, I found them to be ok. I traced the wiring back to a control box at the bottom of the fridge at the back in a white plastic container. When I checked the PCB I could see where something has burnt out and when I unplug the wiring harness that comes from the LED display and controls the LEDS light back-up but I still hav no lights. I spoke to my local parts dealer and they need a part number for the pcb which I am having trouble finding. Can anyone help me with this and also tell me if this will cure the problem. The fridge/freezer however, still appears to be working ok.
