Timothy R Saint Gabriel , LA November 06, 2020 Appliance: LG Refrigerator LFX21960ST/00 Lg Refrigerator Lfx21960st/00: Light console running hot / main control board was out. How to replace Main Electronic Control Board. The light console in out LG refrigerator was running very hot and would periodically be out with the doors open. I used the live chat feature on this site. They were extremely helpful and diagnosed the main board being the problem. They provided the exact part number and a detailed video for repair. The repair video was very easy to follow. I ordered the part and it was delivered in three days. With the help of the video the replacement of the main board took me about 15 minutes and I am not a handyman type. We are now several days post repair and the refrigerator is working perfectly. Thank you so much! We saved $100s vs a professional repair or $1,000s vs a replacement. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
