Re: Water inside Salad/Crisper Drawer under lid.
Ethylene gases some fruit exude has nothing to do with condensation and chiller storage but more to do with cross contamination and decay. (Ethylene bags for bananas works brilliantly by the way, I can testify to that.)
You might like to get a digital thermometer, the sort with a wire probe? Very handy for double checking both inside and outside the fridge temperatures. The salad drawer is the coolest part of the larder cabinet so place the probe in there. On the other shelves ensure there’s no liquids uncovered as that can lead to increased condensation in the coldest areas.
