Start off, I have a 7 year order Frigidaire side by side LGHS2634KEO(Tag says it made by Electrolux, if that matters.)

About 2-3 weeks ago the the fridge/freezer started to make a unusually clicking noise. Sounded like a relay clicking. I asked around and a few people told me to pull the fridge out and clean the coils of the dust. Which I did and that did not stop the clicking, but I noticed when I put the fridge back the freezer side was running and the temp was increasing. The temp in the freezer increased to 12 degrees then went back down to the normal -2 degrees. Now it randomly will do this cycle of the temp increasing to around 12 degrees and then going back to normal -2 degrees. When it started it seem to only do this every other day and now it's once a day. Also the clicking sound is random too, sometimes it clicks every few minutes for about an hour and then sometimes I don't hear the clicking all day. What could this be? Me cleaning the coil damage something?

Fridge side seems to be working fine, no temp change.

Thank you in advance for the help.
