Freezer leaking water into fridge?

We have a whirlpool refrigerator with freezer above and it is dripping water into the fridge below. It has an icemaker as well. Any ideas about what could be the problem and how to fix it?

Most likely the problem is a frozen drain. Remove the rear panel in the freezer and defrost the drain (under the evaporator coil). You can use a hair dryer and/or a turkey baster with hot water.
