Water appears at the bottom shelf below vegggie draw, but there is no place above it or elsewhere that is the slightest bit wet, no place from which it is dripping or flowing from that is evident. There is just this recurring little puddle in the front bottom space under the veggie draw. What is going on?

Wrap a dry towel completely around the outside of the disposal above where you believe its leaking but below any drain. Secure in place with tape and wait. If towel stays dry, then ok its leaking through the bottom bearing and replace unit.

If the towel is wet... keep looking.

seems to be a condensation proble, is it possible to lower down fridge temperature a bit? This may solve the problem.

Most modern fridges have an automatic defrost that works by draining into a sort of funnel above the back of the top shelf.
The funnel is connected through the back of the fridge to a rubber drain tube that goes down the outside of the back to a heated evaporation tray under the fridge,
The hose and/or funnel can get clogged with disgusting yucky stuff, and the water spills over the top of the funnel onto the top shelf.
The fix is to clean all the bits. It's usually no big deal to take apart.
I have resorted to blowing through the tube from the bottom end and then cleaning up the mess, and brushing my teeth. Quite revolting but, that's the price I paid to become an expert.

Hi,have you got a drain at the back of the fridge just above the veg draw,if yes is there eney food above that that is tuching the back wall of the fridge above the veg tray,if so then the water that runs down the back wall will be going onto the food that it tuches and into the veg draw,hope this was some help,all the best.

USUALLY A PROBLEM WITH THE AIR FLOW DAMPER CONTROL AND OR THE FRIDGE THERMISTORS> IS THE FREEZER OK? IF U HAVE A BAD DOOR SEAL OR CLOGGED DRAIN PLUG U CAN GET CONDENSATION THAT MAY FREEZE AT BOTTOM AS WELL

your drain line may be plug up therefore is going above the level make sure you see water on the bottom tray next to the condensing coil under the refrigerator.
thanks.

You didn't say -- was this freezer working correctly for some time before this problem?

It's not unusual for an ice buildup in the icemaker itself to divert water to places it's not supposed to be. The only fix for that is to turn of the freezer (you may have to turn of the refrigerator, too), and completely defrost the freezer. Leave the refrigerator door closed and it will stay reasonably cold. It may take a couple of hours to fully defrost - put some towels in the bottom, as it sounds like you'll have some ice buildup to deal with. You can speed that up a lot with a hair dryer. Just turn it on high, and direct it at the ice buildup, and then concentrate on the icemaker and the area around it.
If you can, inspect the icemaker area and make sure the fill tube is directed into the ice tray, and hasn't gotten bumped or moved so it's pouring water elsewhere.
Once the freezer is completely thawed out and all the water mopped up, start it up again and cross your fingers.

It is sopposed to evaporate

I have a Kenmore 2 door,freezer on bottom, mod# 795.77309600,the shelf that holds the crisper draws cracks,front & back corners, also the back,middle. this is the 2nd time for me. Is there a solution??

basic checks:
is water entering into the machine.
is it hot.
is it being heated during pre-wash
is the soap being dispensed
is the pump running when cycling?
do the arms turn freely?

you mentioned the top and bottom shelves. are there places where the dishes 'are' being cleaned?, or are you meaning that in general they are not being cleaned at all?

most of the above indicators are observable by stopping the wash cycle from time to time in various modes.
to see if water is being pumped at all, put a bowl on the top and bottom shelf, and nothing else. if there is water in it after it cycles then the pump is moving at least some water.
start with these observations and please report back
good luck
