Part: Condenser coils, evaporator fan, thermostat, compressor

Dirty or obstructed condenser coils

How to Identify: Excess dust/debris on coils; fridge struggles to cool efficiently, runs constantly.

Part: Condenser coils

Faulty evaporator fan motor

How to Identify: No airflow sound, refrigerator warm but freezer cold, unusual fan noise.

Part: Evaporator fan motor

Defective thermostat/temperature sensor

How to Identify: Incorrect temperature readings, fridge not reaching set temperature.

Part: Thermistor/temperature control

Refrigerant leak or sealed system failure

How to Identify: Fridge not cooling despite functional fans and coils, hissing sound, frost on lines.

Part: Refrigerant lines/sealed system

Common Issues Reported by Users

  • Faulty temperature control thermostat
  • Defective main control board
  • Blocked condenser coils

User Suggested Solutions

  1. Check and replace the temperature control thermostat. First, unplug the refrigerator. Locate the thermostat, usually found inside the fridge. Test it with a multimeter for continuity. If it shows no continuity, replace with a new thermostat.

  2. Inspect and replace the main control board. Unplug the refrigerator and remove the back panel to access the control board. Check for burnt components or damaged connections. If found, replace the control board with a compatible part.

  3. Clean the condenser coils. Locate the coils at the back or beneath the refrigerator. Use a vacuum or brush to remove dust and debris that may be blocking airflow. Ensure the area is well-ventilated.
