Customer Questions and Answers for Board, L.V. Ice2o by Whirlpool

Paul, It's probably best that you start at the back of the refrigerator, at the main control board WPW10310240 with a meter check pin#1(bk/grn) to pin #2 (rd/bk) on the J6 connector on the board with the harness disconnected, No 12 VDC, would indicate a faulty main control board. If you have the voltage there ,You'll want to remove the upper door hinge cover and check for loose connections in the harness under the cover. Then you will need to access the display board, and check for the 12 VDC in the J1 harness pin#1 (bk/grn) to pin #3 (rd/bk) If you have the voltage there, you will need to replace the low voltage/display board 67006294
