Joseph G Flushing , NY September 19, 2016 Appliance: LG Refrigerator LDC22720ST Lg Refrigerator Ldc22720st / Astclgg: Refrigerator was totally dead. How to replace Pcb Assy, Main. I was very upset that my LG Refrigerator that is only six years old and was totally dead, I googled and found out many people had the same problem. All stated it was the board and easy to repair I was a little nervous as I never did anything like this before but took a shot and glad I did. Ordered the part on Monday morning and sure enough had it on Tuesday afternoon. Took about 10 minutes to swap out. Repair was very easy and AppliancePartsPro was Fantastic getting me the part so fast and getting my frig up and running again so quickly. THANKS!!!! Still upset with LG don't think I will be buying another appliance from them. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
