This fridge has not worked properly from the start. I have had to unplug and defrost it twice this year to get the freezer to work (I can deal with this but mentioned as it may be related). While the freezer will go to whatever temp I want without a problem the fridge stays in the 50's no matter what the digtal temp says - it either says what the temp actually it is or says it is 34 (while the thermometer in the fridge says 56). I have unplugged it, reset the freezer/power freeze buttons, made sure it had plenty of room around it, and completely defrosted it (at least I think so). Nothing seems to change except how the digital temp reads. Can I fix this myself or do I need a service technician?

If the freezer is getting cold and working properly, but freezer is not the it can be defrost issue.------------------ The procedure of this unit
is as follows: --- The compressor starts then it cools the freezer section.
When the freezer reaches its cooling level the defrost cycle starts functioning.
In this cycle the fan in the freezer section starts running and the cool air in
the freezer section is passed to the fridge section and the fridge section
gets cold. The air from freezer to refrigerator passes from the section, in
that section the damper is located.--------- Try manual defrost reset procedure: ---- First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take near to 4 hours to get run in its proper cooling cycle. Then check, if the problem returns again. If the same problem occurs then it's defrost problem. The defrost board and the defrost thermostat/heater is not functioning properly and it has to be checked and replaced. The defrost assembly consists of three main parts. The defrost thermostat, the defrost heater and defrost board. Any of the one is not functioning. When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works. Both thermostat and heater are controlled by defrost board. First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem. You can get required parts from online sites like: --- www.repairclinic.com or from searspartsdirect online site.This should help.Thanks.Helpmech.
Had exactly the same problem. Found the cooling coils are not defrosting, everything was iced up inside the back panels. The drain was blocked, water pooling underneath also.
Remove all the plastic panels in the back of the freezer, including the temp. sensor (unplug) and fan (unplug). Defrost everything with a hair drier.
Make sure that the drain at the bottom is free, a small plastic tube which takes water down into a pan where it is evaporated by the compressor etc.
Replace the defrost sensor - the most likely faulty part. This costs about $Au 20.00 from Samsung (just ask for a defrost sensor for the model of fridge). This sensor fits in a plastic cage attached to the top of the cooling coils, has wires which plug into a socket. Reassemble the fridge and see if this has solved the problem.
If the fridge still does not defrost automatically, you may need to replace the circuit board ($Au 80.00 from Samsung). This board is found from the back of the fridge, in a plastic box behind a back panel at the bottom of the back of the fridge. Lots of wires to unplug!
There may be other problems, like a faulty thermostat on the valve which controls circulation of cold air into the fridge from the freezer, I have no experience of solving this.
Samsung mechanics are HOPELESS in my experience, replacing the two parts above will be less expensive than a call to them. Good luck!
As struck freezer fan by working due to over frosting behind the freezer where FFan is located. Check defroster cycling is working properly. .Keep temp 5 degree and check thermostat, defrost timer and heater working properly. Now defrost manually or unplug fridge. And after defrost, plug it again.
When the freezer section gets cold and reaches
its required cooling temperature, after that the frost on freezer section
starts defrosting and the cooling fan in the freezer section blows this cool
air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the
freezer gets cool but fridge section does not cool.Try manual defrost by unplugging the
refrigerator from main power outlet for 4 hours then reconnect it and check, if
the same problem is noticed again,. If yes then its defrost board problem. The
defrost board located in the back of fridge section. You can get required parts
from www.repairclinic.com or from online sears part site. ------------- Thank
.When you open the door freezer door will get stopped and so, no sound. It will work only when door is closed. Fan sound comes due to malfunction of defrost. If defrost does in right time it won't happens. Unplug and let fridge get defrost all icing. After 3 to 4 hrs,start run again, and set temp @ 5degree freezer. It will start cooling fridge compartment also. But, this is a temerory solution. To solve permanently, find out why defrost not functioned properly? Follow this steps. Check defrost timer working which is back of the refrigerator down corner. By with small tip screw driver in some models located in the ceiling of the fresh foodsection or behind the cold control cover. In the defrost timer,slowly turn the screw like wheel in the middle of the defrost timer withstraight screwdriver until the fridge shuts off. Now it's in defrost. If thedefrost heater(s) starts, replace the defrost timer and defrost thermostat. Ifthe heater(s) does not start, unplug wire cord to check ohm test for continuityof heater. If continuity is there, plug cord wire which gives power 120volts(check specification) to heater. If heater no starts, bypass defrost thermostatby join the 2 wires in the defrost thermostat. If the heater now comes on,replace the defrost timer and defrost thermostat. If the heater itself is bad,replace it. Thanks and hope helpful.
Check freezer fan is working.If ice formed over freezer fan by working. It's a common problem due to irregular defrosting. Keep freezer setting temp at 5 degree. And check defrost timer, thermostat,heater are working properly. Turn timer with small tip screw driver to shut off fridge. If not shut off, replace timer. Turn counter clockwise defrost thermostat. If fridge not shuts off replace defrost thermostat.Check heater by join the 2 wires in the defrost thermostat. And after 1 minute, unplug power and keep your arm on heater. If it's warm heater is o.k. Otherwise, replace heater. Once heater starts work at regular interval controlled by thermostat and timer, defrost will be good and effective cooling will also be in fridge compartment.
Many times a freezer and/or refrigeratordo not work right because of a dirty condenser coil...there are also many otherthings that can go wrong. If you are hearing a clicking or buzzing then checkout the last two tips.
If your refrigerator is running but warm, then...
Check out this tip that I wrote about that... it is a great place to starttrouble shooting your unit...and something that you can do rather then callinga repair person to do a simple thing for you...
What happens is the defrost is controlled electronically from a circuit board, when this goes bad, the freezer quits defrosting, and freezes the fans that circulate air through the fridge side of things.
To check this, unplug the entire fridge, leave the freezer open, wait for it to defrost a bit, if this causes the fridge to start cooling again when you plug it back in, then its the defrost. You should also see ice crystals on the back of the freezer just under the icemaker.
