There are no indications of a leak anywhere. If I saw an oily spot somewhere on the floor or in the fridge, I'd certainly investigate. So, it might be a worn out compressor, but in that case it's more economical to buy a new fridge anyway.

They won't allow me to "top up" the refrigerant charge without finding and fixing the leak, and that part is gonna cost a few hundred dollars cuz of the requirement to evacuate the sealed system and find and fix the leak before adding refrigerant.
Well, now I got lots of spare parts for my other fridges.
