""water in the bottom of my refrigerator and I can't find the drain""
A "frost free" refrigerator really just hides the frost in a hidden basin where it melts and drains through a tube to a pan by the compressor. In a top-freeze, the secret basin is under the freezer floor. And after 18 years, dust and lint and yuck clog the tube. Your basin runeth over, into the main refrigerator bay, and soaks your egg-carton.
General older GE top-freeze. (Kenmore is similar.)
I assume no ice-maker. (I don't have one so I dunno if it gets in the way.)
Take all ice cream etc out of freezer and eat it (or hold on ice in a cooler... need about a half-hour).
Unplug refrigerator. You might be OK just turning to full-warm, but there can be a small fan inside the basin which could run unexpectedly, or nearly-insulated wires, so best to un-plug.
**** Four to six Phillips-head screws in freezer floor, take them out. ****
Gently lift the freezer floor and peek underneath. The drain should be visible and the "yuck" is probably at this end. Poke with a Q-tip. GE suggests a baking soda solution in a turkey baster. That may be good if the "yuck" is not at this end, and you want to try to flush the whole tube.
Put the freezer floor back, put the screws back. Plug-in. Swing a frozen chicken over your head for luck, then re-fill the freezer. Keep your drip-mug in the bottom just in case. Check next day.
