What causes a frostless refrigerator to accumulate water in the bottom under the vegetable drawers?
It can be caused by warm moist air being drawn into the refrigerator through a leak in the door seal. The air cools, and the moisture condenses into water and collects at the bottom. Normally the interior of a refrigerator is lower in pressure and humidity than outside. That helps keep the door closed. If there is a leak in the door seal, then warm air can get in, and so can extra moisture. Try inspecting your door seals, and clean both the rubber seals on the door, and the door jams that they rest against when the door is closed. That might be enough to prevent the leak. It seems strange to be talking about air leaking into a refrigerator, but that is one possible cause. I hope this helps.
