Refrigerator is not cooling enough

I can see that freeze and freezer are cool but not cool enough as they should be. Like in freezer if I keep the water, it is getting colder but not freezing or butter in freeze is cold but not hard. I checked all the cooling settings and everything looks good. This fridge is 2.5 years old and out of warrantee.

Compressor is making clicking sound in every 2-3 mins. Also when i touch the compressor, it is very hot. Also there were some yellow like water below the compressor area.

Can you please help to diagnose the problem?

Thanks,

Sounds to me like you could have 1 of 2 problems either a bad “overload relay assembly” or a bad “compressor” the simple way to test it to unplug the unit and remove the overload relay and shake it. If pieces fall out of it that it is bad. But beware sometimes you can have a scenario where both items fail
