I was having the same problem. You need to replace the High Voltage Control Board, part #AP4014490 (Whirlpool 12920710 High Voltage Control Board - AppliancePartsPros.com). Appliance Parts Pros have the best price around - I can pretty much guarantee you that. It is an extremely simple part to replace. It literally will take you about 5 minutes to install. I only had one issue, and it was with the programming sequence. The board comes unprogrammed, and you are supposed to program using the code noted on the model/serial# panel inside the fridge. I was following the instructions correctly, but the fridge would not accept the code noted on my panel (1412). I was at my witt's end, and I started searching around the web looking for an answer. I found a post on another part supplier's website, where someone was providing the instructions on how they installed and programmed their control board. They said their code was 0302, so I tried that in mine and voila - it was accepted and in minutes the compressor kicked on. The fridge is ice cold and in normal working order. Good luck!
