Lg Refrigerator Error Code: Er dH

The “Er dH” error code on an LG refrigerator typically indicates a problem with defrosting. This error is often associated with an issue in the defrost heater or related components. To troubleshoot the “Er dH” error:

1. 1. Check the Defrost Heater:
   The primary cause of this error is a malfunctioning defrost heater. Inspect the defrost heater for any visible damage or signs of failure. If you find issues, such as a burnt-out heating element, it will likely need to be replaced.
2. 2. Inspect the Defrost Thermistor:
   The defrost thermistor monitors the temperature of the evaporator coil. Check its wiring and connections for any loose or damaged wires. If the thermistor is faulty, it may need to be replaced.
3. 3. Examine the Defrost Control Board:
   The defrost control board controls the defrost cycle. Inspect it for any signs of damage or malfunction. If it’s not functioning correctly, it might need replacement.
4. 4. Manual Defrost:
   In some cases, manually defrosting the refrigerator can temporarily resolve the error. Unplug the refrigerator and let it thaw. Remove any ice buildup in the freezer. Afterward, plug the refrigerator back in and monitor it to see if the error reoccurs.
5. 5. Professional Assistance:
   If the “Er dH” error persists after attempting these solutions, it’s recommended to contact a professional technician or LG customer support for further diagnosis and repair. They can provide specific guidance and ensure that your refrigerator is operating correctly.

It’s crucial to address this error promptly to maintain your refrigerator’s efficiency and prevent further issues. Keep in mind that refrigerator error codes can vary depending on the specific model and age of your LG refrigerator, so consulting your refrigerator’s manual or contacting LG customer support for model-specific guidance is advisable.
