I HAVE A DELFIELD MODEL V18796-DOM-1

SOURCE: not cooling on top

that's very odd...normal air flow is from top to bottom, could be the light is always on, a defective door switch. look at the light and gently close the door, observe the light, it should turn off before the door closes tight.

SOURCE: top of the freezer will freeze but bottom want

Could be same as problem I just fixed.
Remove back panel inside freezer and
1. check fan operation
2. check for ice/water at bottom of the hidden section. There should be a drain hole, which may be blocked by ice. Fix by turning off and pouring boiling water in there until blockage is fixed

SOURCE: top freezes but bottum doesnt cool

The fan has quit working or is blocked. The fan is usually located in the back of the freezer, under a cover. this is easily changed if you have access to parts and a few tools, you can probably replace it yourself. Unplug frig while removing fan and the cover, remove the fan attaching screws, unplug the wire, reverse sequence for installation. It is safe to leave the frig plugged in while you get replacement fan. Whirpool makes Kenmore so you may be able to get the fan at Sears parts center.

NOTE: This
is a multi-solution answer since I don't have all the tech from your question to pinpoint your problem
But the solution is in here generically, if you read and study the solutions very,very carefully.
First I would check cold control. Thats where you turn it off, if your temp is not warm. it can
be defective and not shutting off. If your temp is warm proceed with the following.
I would check the fan in the freezer. Listen to see if it is running
It moves air to the ref from the freezer
Then check to see if FREEZER CONTROL is turned WARMER WHICH MAKES THE REF COLDER AND VICE-VERSA. SEE?
The ref. temp should be about 33-35
The Freezer temp should be 0 to 10 Any thing below these temps is overkill and a waste of elect
The higher the number you turn it up to is the coldest
But is probably a common defrost problem The ice build up
is not being melted by the defrost system.The fan can't blow through the coils into the fridge.
Take out back panel of freezer to check for ice buildup. The coils should be clean.
There are three components to a defrost system- a heater,heater thermostat, and a timer unless you have a defrost electronic card.
Its best handled by a Technician but you could possibly do it by taking your model number to the nearest appliance parts store and asking for the parts. They are mostly located in freezer ,behind back panel on freezer coils.except the card which is usually located in ref The parts store will have info
Also check fan undernearh Ref in the rear
Clean condenser coils underneath
Make sure back cover is on the fridge. Some take them off and throw them away.
make one out of cardboard if its gone, using the holes of the old one.

STOP PAYING FOR EXPENSIVE WATER FILTERS FOR YOUR REF. DO THIS====

-------------------------------------------------------------------------------------------------------
WATER SPLASHING IN FREEZER AT ICEMAKER
THE FILL TUBE IN BACK OF REFRIGERATOR CAN SLIP
AGAINST THE FILL RESERVOIR CAUSING A PARTIAL BLOCKAGE
OR BECOME CLOGGED WITH ICE.
REMOVE THE ICEMAKER AND INSPECT THE FILL TUBE.
RUN WATER IN TUBE TO ELININATE BLOCKAGE AND CHECK
TEMP IN FREEZER. IF TEMP IS BELOW 0 DEGREES, THATS
OVERKILL AND USUALLY A WASTE OF ELECTRICITY TO KEEP IT THAT COLD, NOT TO MENTION THE FILL TUBE FREEZING UP
