LG refrigerator Error dH – Defrost heater issue

The dH error on LG refrigerators occurs when the defrost heater fails, leading to frost buildup. Here’s how to address it:
1. Faulty defrost heater
A burned-out heater prevents proper defrosting.
Fix: Test the heater with a multimeter. Replace it if there’s no continuity.
2. Blocked airflow
Frost can block vents, causing the defrost cycle to fail.
Fix: Defrost the fridge manually and clean the air vents.
3. Malfunctioning defrost timer or control board
These components regulate the defrost cycle.
Fix: Consult a technician to repair or replace the faulty parts.
