Chris G Wisconsin Rapids , WI November 03, 2015 Appliance: LG Refrigerator LFC23760SW Lg Refrigerator Lfc23760sw / Aswclga: No power to my refrigerator. How to replace Main Electronic Control Board. We went online and searched for our problem using the specific model number of our refrigerator. There were many entries related to this, so it was a common problem and many of the people said to was due to a blown fuse.My husband had some electrical gadget that confirmed one of the fuses was blown. It was not obvious by looking at it. According to the online sources, We could replace the fuse, which involved soldering, which we were not comfortable with, or we could replace the whole circuit board.We searched youtube and found videos on how to replace the circuit board, which was easy, if you know how to do it. So we ordered the part and installed it and it worked. Yay Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
