Michael B Holland , MI August 08, 2014 Appliance: LG Refrigerator LFC23760ST Lg Refrigerator Lfc23760st / Astclga: Lg refrigerator had no power. How to replace Main Electronic Control Board. I had no power to my 5-year-old LG refrigerator. Looked around online, and the common issue with LG refrigerators was the control board going out. I found the board on AppliancePartsPros, had it a day later, and popped it in the fridge in about 5 minutes. So easy! I figure I saved myself at least $200 (maybe more!) over calling a repair guy. If it turned out that the control board wasn't the problem, I could have returned it to AppliancePartsPros. I'm adding "Refrigeration Technician" to my resume! ;) 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
