With the help of all the videos on your site relating to this symptom I was able to make an informed choice on a common fix with the thermister. I confirmed the blend door was working, and H2o was present. Changed the thermister and after an hour or so letting the fridge it adjust to the new part, everything went back to normal.
I'm not sure if it said in the videos that some fridges may beep while it adjust to the new part. I thought maybe the part was bad or wrong. But after some time it stopped and is now at the correct temp.
Thanks
