Question

The fridge seems to be working properly (both fridge and freezer) the noise is coming from the fridge side up at the top near the panel where the lights are located. It is kind of like a grind or a buzz last 30seconds to 3 or 4 minutes...Not sure what it could be. Removed the panel below the lights to take a peek but can't see much without removing more of what is up there? Any thoughts or suggestions would be appreciated at this time!!

Thanks
