Clean dust behind an LG refrigerator without opening the rear cover
LG advises unplugging before cleaning dust from the outside of the rear mechanical-compartment cover and leaving any cover removal to a technician.
Dust can collect at the rear of refrigerators over time, but not every model permits the same maintenance. Follow the appliance manual, avoid moving a heavy unit alone and never disassemble the mechanical-compartment cover. Based on LG's official support advice.
