Product review (5 stars): LG Fridge was dead, now back to normal.
My LG LFC20760SW was dead for a full day.  Food was about to be wasted. Both top fridge and bottom freezer had no lights. The control panel had no lights.  And the motor didn't make any noise.  Tested the outlet and circuit breaker if he kitchen, and both worked.  It was a dead unit.

According to some LG forums & a local fridge repair, both said it might be the PCB BOARD.

Called LG directly and I only qualified for the Out of Warranty service for $400.  Inquired with appliance stores and a new fridge cost $1300. So I took the chance, rather than spend on LG's repair people or buy a new one.

Ordered this PCB BOARD, and used the 1-Day Shipping.

Looked up on YouTube how to replace a PCB Board and followed the directions step by step.

Once I plugged in the fridge with the new PCB Board, I immediately heard the motor start.  Opened the doors and all lights were back to normal.

IT WORKED!  Saved myself $250-$1150!
