Important Tips for LG Models

  • Newer LG models with linear compressors have documented issues with compressor failures and start relay problems more frequently in some units.

Possible Causes

Dirty condenser coils

How to Identify: Visible dust, pet hair or debris on coils; fridge running longer than usual; warm compressor area

Part: Condenser coils

Faulty evaporator fan motor

How to Identify: Freezer cold but fridge warm; no airflow or unusual silence from evaporator fan area; warm air in fridge section

Part: Evaporator fan

Damper control assembly stuck or malfunctioning

How to Identify: Fridge warm while freezer remains cold; restricted cold air transfer; damper door not opening

Part: Damper control assembly

Faulty compressor or compressor start relay

How to Identify: No humming from compressor, clicking sounds, fridge and freezer not cooling at all

Part: Compressor or start relay

Ice buildup or defrost system failure

How to Identify: Frost buildup on evaporator coils or back wall, restricted airflow inside freezer/fridge

Part: Defrost heater or related parts

Faulty temperature control thermostat or thermistor

How to Identify: Inaccurate temperature readings, fridge not commanding compressor to run properly

Part: Thermostat/thermistor
