Freezer not workings Click, Buzz for 15 seconds, Click. This happens every 5-10 minut

I opened the freezer today and noticed the things in it were defrosting. I put a thermometer in there and set it to "Coldest" I am getting about 35F right now. Every 5-10 minutes or so, I hear a loud click, buzz for 5-10 seconds, then another click. It is harder to say if the fridge is actually working or not.

I pulled the firdge out, away from the wall to have a look at the back and I haven’t heard the click/buzz sound, I’m not sure if it is just coincidence or not.

What should I check, what do you guys think is wrong? I can post any pics you may need and I can take apart what I can, I am a novice when it comes to electrical repairs but I have a multimeter.

Thanks
