In this video, we analyze two common error codes in Samsung refrigerators and how to fix them.
- Error Code 22E: Indicates an issue with the internal evaporator fan.
- Error Code 23E: Indicates a problem with the external condenser fan.
We will start with immediate solutions and then explore more technical options.
Error Code 22E: Issues with the Internal Evaporator Fan
Possible Causes
- Obstructions in the fan blades.
- Ice buildup preventing movement.
- Defective fan motor.
Immediate Solutions
- Inspect the fan: Check for blockages or damage to the fan blades. Ensure they spin freely by moving them manually.
- Defrost the refrigerator: Unplug the appliance and leave the doors open for several hours to allow complete defrosting.
- Check electrical connections: If the problem persists, inspect the fan’s electrical connections.
Error Code 23E: Issues with the External Condenser Fan
Possible Causes
- Malfunctioning fan motor.
- Obstruction of the fan blades by dust or external objects.
- Loose or faulty wiring between the fan and the PCB (control board).
Immediate Solutions
- Inspect the fan blades: Remove any obstructions that may block the fan’s movement.
- Check the wiring: Ensure all connections are secure and undamaged in the fan’s electrical system.
Technical Tests for Fans in Inverter Refrigerators
If immediate solutions do not resolve the issue, you may need to perform technical tests to determine whether the fault lies with the fan or the control board.
A. Testing the Fan with a 9V Battery
- Disconnect the fan.
- Connect the battery’s positive wire to the fan’s positive terminal and the negative wire to the fan’s negative terminal.
- If the fan does not operate, consider replacing it.
B. Testing the Fan Signal with a Multimeter
- Set the multimeter to direct current (DC) mode.
- Place the black probe on the negative terminal of the battery and the red probe on the fan’s signal wire (usually white).
- The display should show approximately 2.5 volts, indicating the fan is functional and sending signals to the control board.
C. Testing the Fan Signal Frequency
- Use a digital multimeter with a frequency (Hz) function.
- Place the negative probe on the battery’s negative terminal and the positive probe on the signal wire (usually white).
- The frequency value should read approximately 70 Hz.
D. Final Diagnosis
- If the fan operates correctly, the issue likely stems from the control board powering the fan.
