LG Refrigerator Er dH FAQs
Er dH is a defrost error. The defrost system didn’t warm the evaporator enough during a defrost cycle, so ice builds up and blocks airflow.
Unplugging can melt the ice for a while, but the code usually returns because a defrost part has failed. A technician should test the heater, fuse and sensor.
It can become urgent. As ice builds up, cooling drops and food can spoil. Schedule service soon after the code appears.
Common repairs are the defrost heater, defrost fuse or sensor, and sometimes a relay on the control board.
