Why do I have water in my refrigerator, I mop it up and a few days later there is more water there.

Most have a drip pan in the bottom, under the cooling compartment, that drains from a small drain hose.

Sometimes this little escape drain gets clogged. I would try to locate the spot where it drains into the drip pan and run a small piece of wire up the drain hose and see if you can nudge it loose.

Good Luck!
