l am working on these LG GSJ960PZBZ refrigerator (5 of them withe same problem)which is showing the error code OF and F. The temperature cannot be set. The compressor does not come on. The small red LED on the control board does not come on at all. Please l need help. Thanks

Thanks please l have done what the site(https://www.google.com/url?q=https%3...moveandreplace.) recommended but still the refrigerator will not work.

What site? The site you provided above is useless gibberish.
I think you mean this site:
https://removeandreplace.com/2016/02...-how-to-reset/

Perhaps one of these other instructions for doing the reset will work
better:
http://www.lg.com/us/support/product-help/CT10000021-1337637756594-ff
http://www.manualsonline.com/support/lg/refrigerator/demo-mode-866733
https://www.shopyourway.com/questions/1094845
etc... or even a video:

Keep trying. It should work eventually. If it continues to not
reset, have someone else follow the instructions WITHOUT YOUR HELP and
see if that works any better. Assumptions, bad timing, fumbling with
the buttons, or not hitting and releasing both bottons at exactly the
same time, might have an effect.

Also, make sure the refrigerator is plugged in and turned on while
doing the reset. Don't laugh, but I had to help an "installer" do the
reset once, only to find out that he failed to turn the refrigerator
on because the printed instructions didn't tell him to do so.

Good luck.
