To start unplug the fridge from power for ten minutes, this will reset the control board.

It looks like the fridge may have a faulty control pcb, or a faulty thermostat sensor.

Check first that the evaporator system (fan and heating coil) located behind the freezer firewall is working.
Eventually try defrosting the appliance overnight.

If that does not fix the problem, test and eventually repace main control pcb and sensor.

You get parts here.

Sorry to read about your problem, I hope this helps you out.

Failure of BLDC Fan Motor at Freezing Compartment Er FF

If there is no fan motor signal for more than 65sec in operation fan motor
Poor motor, hooking to wires of fan, contact of structures to fan, snapping or short circuit of Lead wires.

Unplug unit for 10 sec, then see if the problem comes back. If it does, i assume you maybe under warranty.

Freezer temperature v


This sounds like your motherboard,computer or control board(they call it different things in different models) is bad. It is responsible for the fan speed and timing of the defrost cycle. To locate your timer, motherboard, control or adaptive defrost control , enter your model number and search for the part or post back on Fixya.

Freezer always about same temp as the upper refrig section


Check those coils underneith. They are making the machine work harder IF they are dirty. They may be full of lint and cobwebs. All that needs to be removed.

Samsung refrigerator freezer not freezing


-2 although below freezing temperature, is not really enough to keep food really frozen. I am presuming we are talking in Celcuis. You need to set the freezer to a lower setpoint.

You have a clogged defrost drain tube. best way is to thaw unit out. Your vents are being blocked so no air flow is pushed down.
