There is frost buillding up just below the halfway point in the fresh food section starting from the center going to the right. the fresh food section is not cooloing properly. What could the problem be?
A refrigerator or freezer that is cooling, but cooling poorly, may have a problem in one of several areas:
Evaporator coils
Condenser
Poor
cooling is often the result of a heavy frost build-up on the evaporator
coils or a condenser that is clogged with dust, lint, and dirt.
Evaporator coils
Poor cooling is often the result of a heavy frost build-up on the
evaporator coils. You can't see these coils without removing a panel on
the inside of your freezer. A sure sign that there is a build-up is the
presence of any frost or ice build-up on the inside walls, floor, or
ceiling of the freezer. Such a frost build-up usually indicates a
problem in the self-defrosting system or damaged door gaskets.
The
refrigerator is supposed to self-defrost approximately four times in
every 24 hour period. If one of the components in the self-defrosting
system fails, the refrigerator continues to try to cool. Eventually,
though, so much frost builds up on the evaporator coils that the
circulating fan can't draw air over the coils. There may still be a
small amount of cooling because the coils are icy, but with no air flow
over the coils, cooling in the refrigerator compartment is quite
limited.
Here's an inexpensive, though inconvenient, way to
determine if the problem is with the self-defrosting system. Remove all
of the perishable food from the refrigerator and freezer, turn the
thermostat in the refrigerator to Off, and leave the doors open for 24
to 48 hours. (Be sure to have several towels ready in case the melting
frost and ice causes the drip pan to overflow). This allows the
refrigerator to defrost "manually." When the frost and ice build-up has
completely melted away, turn the thermostat back to a normal setting.
If the refrigerator then cools properly, it indicates a problem with
one of three components in the self-defrosting system:
If it still
does not cool properly, there may be a problem with the refrigerant
level or the compressor. You may need to consult with a qualified
appliance repair technician to further diagnose the problem
Condenser
Self-defrosting refrigerators all have a set of coils and a cooling
fan, usually under the refrigerator, that need to be cleaned regularly.
If these coils get coated with dust, dirt or lint, the refrigerator may
not cool properly. The coils may appear to be a thin, black, wide
radiator-like device behind the lower kick-panel. To clean them,
disconnect the refrigerator from the power source, use a refrigerator
condenser brush (see the Appliance Accessories section) and your vacuum
cleaner to clean the coils of any lint, pet hair, etc. You may not be
able to get to all of the condenser from the front, it may be necessary
to clean the remainder of the condenser from the rear of the
refrigerator.
This could also be due to a problem with the air baffle unit, or the evaporator
fan, wherein cold air from the freezer does not get directed into the
fridge section. Could even be a bad door switch preventing the fan
motor from running.
If you find that the freezer is not cooling as well, it could indicate a problem with the compressor.
In
any case, I would recommend you contacting a professional to service
this. If it is under warranty, then best contact the manufacturer or the
point of purchase.
Hope that helps! Should you have any further questions,
please feel free to post them here.

Hi,
The problem is with the damper door.Please check that it is not cracked.
I am really sorry please ignore my first post as it was for my another client.
Ok now coming to your problem:
1. You need to use thermometers. Test the freezer temp for a while. Then the refrigerator compartment for a while.
2. Does the compressor run AND also the evaporator fan run (the later
of which is located in the back wall of the freezer compartment)? They
should be.
3. Do you see any water down in your drip pan that should be either
located under your refrigerator (accessible by removing the grill at
the bottom front of the refrigerator, which just snap off and back on),
or ontop the compressor at the back? If there is no water at all, based
on your symptoms, you could have a case of frozen defrost water at the
cup that allows this drainage to go through the cup and then tube, back
of the refrigerator and down a tube into the drip pan. Check for ice in
and around that cup which is located at the top rear of the
refrigerator compartment. If that is clogged, chances are ice has
formed, blocking where freezer air gets into the refrigerator
compartment at the upper rear of the refrigerator compartment.
If this is what has been going on, what I do is...first unplug the
refrigerator...then take food out of the freezer and put it in the
kitchen sink basins and blanket or towel over it to keep it froze. I
also move out of the refrigerator compartment the food most likely to
spoil quick... like the milk, and some other stuff, and to clear away
stuff in the area of the defrost drain cup. Then I use a hair dryer to
thaw for a bit back at that cup. Then when I can tell that the cup is
thawed...then I pry off the flexible rubber or plastic cup and then use
a piece of tubing I carry with me, and put the tubing (you can buy this
at home centers, hardware stores and auto stores) and jamb it in the
defrost drain tube hole and blow and see if you are able to blow out
any gook (if your tube is a little ill-fitting you may have to wad a
rag or toweling aroudn your inserted tube to get a better seal when you
blow). When you know you are able to blow through the line and see
evidence of it in the drip pan below, then you can replace the drain
cup. You may also be able to do this job from reverse by simply
removing the drain tube from below, where it sets in (just above,
actually) the drip pan below, and then blow *up* the drain tube. After
doing this, knowing the tube and cup are clear...Then place the
hairdryer in the freezer compartment...shutting the door on the cord,
and let it run inside to defrost the refrigerator. Then the thawing ice
from the evaporator coils and maybe around the fan will thaw and run
out into the cup and down the tube into the drip pan. Look to see,
after you have been defrosting for say 15 minutes, to see if you are
getting lots of water to now thaw and drain into the drip pan below. If
you see such evidence, then you will know that this was what your
trouble was all about.
Goodluck..
