What site? The site you provided above is useless gibberish. I think you mean this site:

Perhaps one of these other instructions for doing the reset will work better: 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.
