Erro code 1F

With all that I'd be suspect of the voltage where your plugging in good ground ect. do you have any other electronic issues in the house? theirs a root problem being missed . Tom

I did notice the relays on the replacement boards are made by another manufactuer than my original board and they at least look better for whats that worth. I have a feeling these boards are a fast moving parts for andrewselectronics.com and LGUSA.com.They should extend warranty for such a "buggy" board and throw in a redesigned ice maker along the way.Visit andrews and notice that the board is the first listed part in stock available for the fridge at a lofty 300 bucks.might be worth delving into repairing the board in the event the crummy relays are the failed parts on the board as they look and smell to be (hot). also would break the chain with the little board racket LGs got going on....

As recommended by the repair tech after my first warranty repair (refrigerator fan and main board) I installed a surge protector on the electrical outlet that powers my refrigerator. The board that was replaced actually had a burn mark on it where one of the components had fried.
I used a plug in surge protector that is made for use in offices for copiers and large printers since it has the capacity to handle a refrigerator load. Standard computer plug strip surge protectors are not large enough.
I have not had any electrical problems since then although the ice fan froze and was replaced a year later. The main board was replaced again at that time presumably to meet the Energy Star settlement as well as the ice maker issues.
