The 23 c error code on a Samsung refrigerator indicates that the unit's evaporator fan motor has failed. This error code can occur for a number of reasons, including a blown fuse, a faulty control board, or a problem with the evaporator fan motor itself. If the 23 c error code is displayed, the first thing to do is check the fuse and, if necessary, replace it. If the fuse is not the problem, then the control board will need to be replaced. Finally, if the control board is not the problem, then the evaporator fan motor will need to be replaced.
1. Check the power supply
- Check the power supply by plugging in a known good power supply and checking the power light on the front of the refrigerator. If the power light is on, the power supply is working and the 23 c error code is most likely the result of a malfunctioning power supply.
- If the power supply is not the problem, check the power cord for damage. If the power cord is damaged, the refrigerator may not be getting power from the power outlet.
- Check the power supply voltage by checking the voltage at the power supply outlet. If the voltage is low, the power supply may be damaged and the refrigerator may not be getting power.
- Check the power supply by plugging in a known good power supply and checking the power light on the front of the refrigerator. If the power light is off, the power supply is not working and the 23 c error code may be the result of a malfunctioning power supply.
- If the power supply is not the problem, check the power cord for damage. If the power cord is damaged, the refrigerator may not be getting power from the power outlet.
- Check the power supply voltage by checking the voltage at the power supply outlet. If the voltage is low, the power supply may be damaged and the refrigerator may not be getting power.
2. Check the door sensor
- Remove the front panel of the refrigerator.
- Check the door sensor. If it is not working, replace it.
- Reconnect the power cord and the sensor.
- Replace the front panel.
3. Check the evaporator fan
- Check to see if the fan is spinning. If not, then the fan may be broken and needs to be replaced.
- If the fan is spinning, then the problem may be with the wiring. If the fan is not spinning, the problem may be with the evaporator fan motor.
- If the wiring is not the problem, then the motor may be the problem. To test the motor, remove the cover and check for continuity between the motor and the fan blade. If there is no continuity, the motor may need to be replaced.
4. Check the condenser fan
- Open the refrigerator and locate the condenser fan. If it is not accessible, remove the top panel of the refrigerator.
- If the condenser fan is accessible, remove the cover and check the motor for damage. If the motor is damaged, the fan may not operate and the refrigerator may not cool.
- If the motor is intact, check the blades for dirt, debris, and corrosion. If the blades are dirty or corrosion is present, the fan may not operate and the refrigerator may not cool.
- Replace the condenser fan if necessary.
