why does my hotpoint fridge freezer make a noise

I’m having an issue with my Hotpoint fridge freezer. It’s making a noise that’s quite loud and I’m not sure why. I’m hoping someone can help me out and explain what might be causing it. I’ve tried to look up the issue online but haven’t been able to find any information. I’m not sure if it’s something that I can fix myself or if I need to call a professional. Any advice would be greatly appreciated.
