You will need to pinpoint where the clicking noise is coming from. Inside the refrigerator? Inside the freezer? Pull the refrigerator out from the wall and remove the lower back access panel and see if its coming from back there too.
Is it cooling properly?
Also make a video of it and upload it here please.
The refrigerator is still cold and the clicking sound is on the outside. The fan was running when it made the sound. I did hear a normal humming sound after the clicking. Also, it was doing the click noise a few times in a short time, and it stopped for a few hours.
