Okay, maybe an exaggeration, but I do have a frost-free fridge in my attached garage that every couple of days wants to release a large puddle of water. The fridge is NOT connected to a water line. There is A/C in the garage and I keep it around 80. Without the A/C, it will get as hot as an oven after you park two hot cars in there. Dunno what the humidity level is, but we've had the fridge there for several years and never had this problem before. I am conversant in theoretical physics and I know what condensation is. What should I look at first?
Is there something blocking the air around the mechanicals?
In reply to wvumtnbkr:
Probably. I haven't ever vacuumed the coils and there's a ton of crap piled up around it. Is that bad?

with mine every couple of days the frost free cycle will drip into a pan that then evaporates. I wonder if you pan has become dislodged or corroded through and is now dripping directly to the floor.
Easy answer: Evap tray rusted thru or coils are clogged with dirt.
Crappy answer: Leak/low freon condition
I will go and clear out around it. There appears to be no access to a drip tray via the front of the unit like my side-by-side in the kitchen. This one is a conventional top-freezer fridge.
Make sure a pet of child is not peeing in the corner. Seriously, this has happened to me.
More likely, the evap tray is not evaping. It is not hot enough to evaporate the water away or there is too much water collecting, or the line to the tray is not connected.
No pets, and children are past that age. It's water, not pee. Trust me, I know the difference!
I was mistaken about the front grille. There is one, just not as large as I expected, and all but invisible until you open the fridge. There was only a light coating of dust on the coils behind there and I vacuumed it out as best I could.
The rear of the fridge looks pretty normal also. There is a cooling fan, and it is running. What appears to be a drip tray is dry. Somehow, there is water that is not going where it is supposed to be going.
Likely condensation problems. I have a fridge upstairs at the shop that seldom gets opened, and sometimes it drools a bit.
I bet there's a small tray with a drain hole at the bottom or even a hole in the bottom rear of the fridge that goes to a hose that then leads to the drip tray. That hose is plugged or disconnected or the rubber has rotted through. Clean reattach or replace it and you'll stop having water accumulation.
How are the door seals? Do the doors close really well all around? More air in/out = more water.
In reply to dculberson:
After looking it over and cleaning everywhere I could, I'm forced to conclude that this is likely. Unless I empty the fridge and lay it on it's back, I'm not going to be able to access the area, so I guess I'll put up with it for a while. Thanks to all who offered their advice!

This is probably relevant. I will check it more closely. Also, kids have been known to leave the door open for extended periods, but this is infrequent.
