Urgency: High

Important Tips for Daewoo Models

  • Common reported causes include evaporator fan motor, condenser fan motor, temperature sensor, and start relay/capacitor issues for Daewoo refrigerators.

Possible Causes

Insufficient airflow/circulation inside fridge

How to Identify: Cold air not reaching certain areas; shelves or food blocking vents; freezer may be cold but fridge section warm

Part: Airflow paths / vents

Dirty or dusty condenser coils

How to Identify: Condenser coils covered in dust/debris at back/bottom; fridge runs but fails to cool effectively

Part: Condenser coils

Evaporator or condenser fan motor failure

How to Identify: No airflow noise from fans, freezer cold but fridge section warm, fan blades won’t spin freely

Part: Evaporator fan motor, condenser fan motor

Thermostat or temperature sensor malfunction

How to Identify: Temperature control settings have no effect; erratic temperature readings

Part: Thermostat / thermistor

Start relay/capacitor or compressor failure

How to Identify: Compressor fails to start properly, humming noise, trips breaker, or never reaches proper pressure

Part: Start relay, start capacitor, compressor

DIY Solutions

Clean condenser coils

Improve internal airflow

Easy 5-10 minutes
  1. Rearrange items to avoid blocking vents and airflow paths.
  2. Ensure no food or containers obstruct vents.
  3. Check after several hours if cooling improves.

Check and free fan blades

Moderate 15-30 minutes
Tools Needed: screwdriver
