Refrigerator door hinge loose

[moonshadow]

Hi. The hinges on my refrigerator door are loose where they attach to the wall/frame of the refrigerator. I’ve been trying to figure out how to tighten them. No visible means of attachment. I tried removing the door frame trim expecting to find some nuts etc. Nothing there. So now I am wondering if some wood screws hold the hinges to the frame/wall that I can’t see without removing the hinge pins and looking. Of course the hinge pins are frozen in the hinges. Penetrating lube and moderate hammer use didn’t get the pin moving. I’ve only got about a month left on this trip so I’m tempted to leave it alone till I get home and find a bigger hammer (😁) or some other tool to attack the pins. One concern is that since the door is a bit loose condensation seems to be starting to discolor the wood and I want to avoid any rot.
So, anyone ever successfully remove or tighten the hinge to the boat?
Thanks. Paul
