Samsung side by side refrigerator error code repair guides
1C or 1E blinking error
Freezer Sensor error.
Open the freezer duct in freezer compartment and check the sensor connected in freezer duct and or othe location except on evaporator.
That is called freezer sensor and it has been either short or open.
Check the ohm value of sensor with multimeter set on 20..K range, if it show 0 or 1 then replace it, if it show 4K to 6K at normal room temperature then check its wiring and connectors if it braocken or gone rusty. If wiring and connectors are ok then replace main pcb.
2C or 2E blinking error
Fridge sensor error.
Open the fridge duct in fridge/Ref compartment and check the sensor fixed in duct or other location except evaporator coil that is called ref sensor, and check it on multimeter.
set on 20..K range, if it show 0 or 1 then replace it, if it show 4K to 6K at normal room temperature then check its wiring and connectors if it braocken or gone rusty. If wiring and connectors are ok then replace main pcb.
4C or 4E blinking error
Freezer defrost sensor
Open the freezer duct in freezer compartment and check the sensor connected on evaporator coil.
That is called freezer defrost sensor and it has been either short or open.
Check the ohm value of sensor with multimeter set on 20..K range, if it show 0 or 1 then replace it, if it show 4K to 6K at normal room temperature then check its wiring and connectors if it braocken or gone rusty. If wiring and connectors are ok then replace main pcb.
6C or 6E blinking error
Room ambient sensor error
Open the panel of main PCB and check if any sensor available near by or open the uper hinges cover and check if sensor is available there.
That is ambient sensor. Remove and check on multimeter.
Check the ohm value of sensor with multimeter set on 20..K range, if it show 0 or 1 then replace it, if it show 4K to 6K at normal room temperature then check its wiring and connectors if it braocken or gone rusty. If wiring and connectors are ok then replace main pcb.
8C or 8E blinking error.
Ice maker sensor
Open the freezer and check a sensor available connected to ice make unit.
Remove and check on multimeter.
Check the ohm value of sensor with multimeter set on 20..K range, if it show 0 or 1 then replace it, if it show 4K to 6K at normal room temperature then check its wiring and connectors if it braocken or gone rusty. If wiring and connectors are ok then replace main pcb.
13C or 13E blinking error
Humidity sensor
Open the fridge/ref compartment and remove duct.
Open the fridge duct in fridge/Ref compartment and check the sensor fixed in duct or other location except evaporator coil that is called humidity sensor, and check it on multimeter.
set on 20..K range, if it show 0 or 1 then replace it, if it show 4K to 6K at normal room temperature then check its wiring and connectors if it braocken or gone rusty. If wiring and connectors are ok then replace main pcb.
21 C or 21 E blinking error
Freezer fan motor
Open the freezer duct and check if freezer fan jam or blocked or connectors has been rusty. Check fan motor on 12VDC supply externally if not working then replace fan motor.
23 C or 23E blinking
C fan error
Fan near compressor is not working. fan jam or blocked or connectors has been rusty. Check fan motor on 12VDC supply externally if not working then replace fan motor.
24 C or 24 E blinking error
Defrosting error
Check heater, thermal fuse and defrost sensor.
26 C or 26 E blinking error
Icemaker error
Check if water supplying properly in icemaker by pushing test switch given below icemaker unit.
Check if working then replace icemaker unit.
27 C or 27 E blinking error
Damper heater error
Check the connection of damper if it is proper then replace damper.
41 C or 41 E blinking error
Communication error
Error seen if display and main pcb connection are broken.
Check wiring continuity and connectors. If these are ok then
Replace display, and or main pcb both.
44 C or 44 E blinking error
Communication between main pcb and inverter pcb.
Check wiring and connectors if it found ok then replace both pcb.
C71 OR E71 if freezer sensor sense rise in temperature in freezer compartment. Reason may be Freezer defrost cycle not working Freezer door was opened for long time. Gas related issues. C72 or E72 Fridge section abnormal temperature. Check as C71 given above. C81 or E81 Compressor starting issues Reason 1-Gas choke 2-Condenser fan not working 3-Compressor locked 4-Inverter pcb fault 5-Input power supply C82 or E82 Inverter pcb fault C83 or E83 Compressor wiring issues. C84 or E84 Compressor locked. Replace compressor. C85 or E85 Low voltage input supply. Check voltage Check inverter pcb, replace it if required. C86 or E86 Over voltage Check input power supply voltage. It should be under 250 VAC.
