What causes water to accumulate in bottom of refrigerator? Temperature seems ok in freezer and refrigerator, and there is no frost in freezer or on coils.

Is the drip pan on the bottom of your frig full? If so you need to dump it. I beleive the water comes from the condensation?

Most frost free refrigerators have a small trough under the evaporator coil in the back of the freezer and fresh food area. When the fridge goes into a defrost cycle the frost accumulated on the coil melts and that water drips into the trough. At one end of the trough there is a drain, much like a gutter and downspout, from which you'll find a small diameter tube which runs down the back to a drain pan that usually sits under the bottom of the refrigerator. Over time this little drain tube collects crud and eventually gets clogged, then when your fridge goes into defrost and the frost melts the trough overflows and the water ends up on the bottom of the cabinet. Your mission, should you decide to accept it, would be to unclog the drain tube, or replace it, whichever is easiest. You can try running a thin piece of wire down through it and then flush it with water. I'm thinking replacement. Use the old tube to pull the new one through.

It is not necessarily the drip pan that is full. In self defrosting refrigerators, condensate is collected in a pan under ther evaporator coil in the freezer durring defrost cycle. This water goes down a tube, usually on the back of the refrig. to the pan under the refrig. where it evaporates back in to the air.

If there is a blockage in this tube, the water will overflow the pan and go down the inside of the refrig. and collect on the bottom inside.

Check this tube to be sure it is clear and also the tube coming from the pan in freezer compartment. Most times you can blow these clear with your mouth.

Look in the refrig. top-cneter, just below the freezer. You might see this tube where it comes from the freezer and goes through the back, outside of the box.

You may have to disassemble the freezer compartment if blocked really bad on the inside.

WOW

PS: If it has been really humid in your area, this could be from condensate on the walls of your refrigerator from opening the door to much. If the walls are dry, the above applies.
