Understanding and resolving the Samsung refrigerator 24C or 24E error code:

Encountering the 24C or 24E error code on your Samsung refrigerator indicates a problem with the freezer’s defrosting system. The error stems from either incomplete defrosting, leading to ice buildup, or an issue with the freezer defrost sensor not reaching the desired temperature during the cycle, signaling a possible component malfunction.

Possible Causes of the Samsung Refrigerator 24C or 24E Error Code:

Several factors can cause the 24C/24E error to rear its frosty head:

  • Faulty Wiring: Damaged wires can cut off power to the defrost system, leaving it unable to do its job.
  • Blown Thermal Fuse and/or PCB Fuse Block: This safety device might trip if things get too hot, prematurely ending the defrost cycle.
  • Defective Bimetal Switch: This temperature-sensitive switch might get stuck in the “off” position, preventing the defrost heater from activating.
  • Malfunctioning Defrost Heater: This component is the ice-melting muscle, so if it’s not working, defrosting won’t happen.
  • Faulty Main PCB: The refrigerator’s control board, or “brain,” might be experiencing issues that affect defrosting and other functions.

Troubleshooting Steps for the Samsung Refrigerator 24C or 24E Error Code

Here are the steps to troubleshoot a freezer defrost error:

1. Unplug and Defrost Manually (Temporary Fix):

  • Remove all food items from the freezer and store them in a cooler to avoid spoilage.
  • Unplug the appliance from the power source.
  • Open the freezer door and allow the ice to melt completely.
  • This may clear the error temporarily, but proceed with further troubleshooting to address the root cause.

2. Address moisture buildup:

  • Locate the connector between the defrost system components and the main PCB (printed circuit board). It’s usually found behind a panel in the back of the appliance.
  • Disconnect the connector carefully.
  • Clean the connector’s pins thoroughly with a dry cloth or contact cleaner to remove any moisture or corrosion.
  • Allow it to dry completely before reconnecting it.

3. Clear blockages in the defrost drain hose:

  • Locate the defrost drain hose at the back of the freezer’s evaporator cover assembly.
  • Carefully clear any buildup of ice or debris using warm water, a steamer, or a defrosting tool.
  • Ensure that the water flows freely through the hose.

4. Inspect the wire harness.

  • Visually examine the wires in the defrost system for signs of damage, such as fraying, cuts, or loose connections.
  • Use a multimeter to check for continuity between the heater, bimetal, thermal fuse, and main PCB.
  • Replace any damaged wires.

5. Test defrost components:

  • Disconnect each component from the circuit and test it individually using a multimeter.
    • The freezer defrost bimetal should read closed (0.1–1.2 ohm) at room temperature and open around 140°F (60°C) when gently warmed.
    • The freezer defrost thermal fuse should read closed (0.1–1.2 ohm) at room temperature.
    • The freezer defrost heater should read approximately 63 ohms.
    • Freezer defrost sensor: compare its resistance reading to manufacturer specifications and replace it if necessary.

6. Replace defective components:

  • If any of the tested components are faulty, replace them with compatible parts.

7. Check the Main PCB (Last Resort):

  • If all other components test correctly, the main PCB itself may be faulty.
  • Replacement of the main PCB will be required.

Important Safety and Documentation:

  • Take photos or notes during disassembly to aid in reassembly.
  • Double-check all wiring connections before powering the fridge back on.
  • Refer to your specific model’s manual for accurate component locations and troubleshooting procedures.


The Samsung refrigerator 24C or 24E error code points to a freezer defrosting issue, particularly with the defrost heater. This comprehensive guide equips you with the knowledge and steps needed to diagnose and resolve the problem effectively.
