Question about Refrigerators
Hi, I have a Samsung rs21 side by side fridge freezer and the freezer is working great with no problems. The fridge however works for two weeks then the display flashes 6 and the first time this happened we used an hair dryer to melt the ice and it worked again for a further two weeks and now it's gone again with the same issues. I have defrosted the fan and coils slowly with an hair dryer and on powering up the fridge with the front twin cooling section out but the fan plugged in the fan doesn't spin at all. Would this be a fan issue or a problem with the thermostats? Any help would be great and also is it a easy fix? Many thanks Wayne
It's a defrost sensors issue. You need to replace the evaporator assembly it will come with all the sensors you need.

Generaly the control board controls everything sometimes you have a bad thermister GE has a help line I beleive it costs 20.00 bucks but you will need a meter and know how to use it and they willl talk you thru the repair .

These usually have one compressor and an evaporator on each side with a fan. check the fans first then the defrost timer, heater and limit thermostat.

When the fridge side is getting too cold or icing up, this is because the control of the compressor has gone bad in some way...
There a few different things that could cause the unit to lose control over the temperature of the fridge side.
If your refrigerator has a damper door that opens and closes to allow cold air to move to the fridge side the damper linkage or the damper motor may have broken or gone bad.
The coils in your fridge may have frozen over and now the air does not move at all so then the ice builds up and can freeze parts of the fridge side.
The thermostat has gone bad and so now the compressor runs continually. This will not be noticed readily on the freezer side but will show up quickly on the fridge side.
Many newer model refrigerators use an electronic sensor or thermistor to read the temperature and supply the info for the circuit board and often a digital readout.
So, here is how I would go about troubleshooting this problem.
Check the coils for ice, defrost the coils with a heat gun or hairdryer, then check for the reason why they iced over. Defrost control or defrost timer bad? Evaporator fan bad?
Check the damper door to see if it is stuck in the open position. If it is then check the motor and the linkage.
Check to see if the refrigeration unit will shut down if the thermostat or digital setting is turned up to a higher temperature. If it continues to run then find the cause and fix it. It may be a bad thermostat, sensor, or control board.
Sometimes with a change is weather to a cooler climate this will be enough to also affect the inside temperatures. Make sure that a bit of adjustment in the thermostat or setting of the temperature will not solve your problem very simply.
I hope the above helps.

Is the fan blowing in the freezer section? Also, check to see if you have airflow thru the damper (vent) in the frig section.
