Make sure your fan is working ,its located behind the freezers back wall. If it is working the vent from the freezer down to the refrigerator may be blocked (usually with ice).With out a fan you have no circulation but your freezer may look likes its working,it may last 3 days.Also if you can move everything out unplug it turn it off w/ doors open untill all traces of ice are gone this will free up any clogged tubes. Good luck.

OK now I'm wondering are theses numbers your getting 4 -9 the actual temps of the refrigerator and the freezer? and do they feel this cold and correct to you? I know the refrigerator side shouldn't be below 34 or so and definitely not below 32. If this is correct and the numbers are not settings but temps. (Now if you have a touch pad its electronic. If it has knobs it has a separate defrost and thermostat and are electro-mechanical)
If electronic Your control board and possibly defrost control are out.
It would more likely be the sensors going to the board(s) It will both sensors have the possibility of causing your problem. 1 will control the run of the compressor (and this one could and probably is connected to the inside coil) and 1 will control the air damper tween the refdg and freezer compartments, and may turn on the inside fan operation too.
(this would be my first suspect if these are degrees numbers). Look at the thermostat control see if it is attached to the indoor coil (usually the tube leavign the indoor section. If its not attached its not sensing the coil temp and when goes into defrost wala its not senmsing temps like its designed to do. Look for a broken clip or possible a plastic wire tie that holds this sensor in place.
Please get back to me with what you see - find on this look up.

Defrost Problem
Error
Code - erdh
Kenmore
and LG 795 Series. Model 795.77556600
but most models use the same repair.
Controller Part # 6615JB2005H
To
Verify correct part. Check part number
for your model number at www.searspartsdirect.com
Don't
be intimidated by this repair... The
'erdh' error code indicates - error defrost heater. Replacing the controller is EASY. The difficult part is removing everything in
the freezer section to access the evaporator coil but hang in there and stay
with it. You will not hurt anything if
you use common sense.
The
new part (defrost controller) is relatively inexpensive ranging $10 - $14. Here in the SouthWest I used Appliance Parts
Depot for a $10 part cost. Don't forget
to have 3-4 small wire ties to secure the defrost heater, defrost sensor and
wires.
It
would help to write down a few notes of some of the particulars during
disassembly.
I
had the same ERDH error code, and my refrigerator began to warm up. I replaced
the defrost thermostat assembly part # 6615JB2005H which is located inside the
freezer, on the right side behind the white plastic panel.
(See
Diagram Image) I accessed it by removing the freezer door, all components
inside the freezer, including the slide rails / tracks mounted on the sides of
the freezer. Be careful when removing the rear white panel because an
evaporator fan is mounted on the back of it and plugs into the back left side
of the freezer compartment. You just
saved yourself about $375 or more.
Stay
With It & Good Luck!
