Samsung Refrigerator: not cooling

Professional Repair Guide

What is this symptom?

Is your Samsung refrigerator not cooling properly? Despite the lights being on and the compressor running, your fridge may fail to maintain the right temperature, leading to food spoilage and warm air. Common causes include incorrect settings, obstructed airflow, and dirty condenser coils.

Urgency: High

Important Tips for Samsung Models

  • Many Samsung models have a Demo/Display mode that disables cooling; ensure it is turned off.
  • Samsung official support recommends checking settings, door seals and resetting fridge as first steps.

Possible Causes

Incorrect temperature settings or modes (e.g., demo mode)

How to Identify: Check if fridge is in Demo/Display mode or if temperature settings are set too high.

Part: Control panel/settings

Obstructed airflow inside fridge/freezer (items blocking vents)

How to Identify: Cold air not circulating; vents blocked by food/containers.

Part: Airflow vents/air circulation

Dirty condenser coils causing poor heat dissipation

How to Identify: Back or bottom coils are dusty/covered and the fridge runs longer without cooling effectively.

Part: Condenser coils

Insufficient external ventilation/heat build-up around unit

How to Identify: Fridge installed with no clearance to wall/heat source nearby; feels hot outside.

Part: Refrigerator exterior/installation environment

Faulty evaporator fan or air circulation fan

How to Identify: No airflow sound from fan area, different temperatures between freezer and fridge sections.

Part: Evaporator/fan motor

Compressor or sealed system failure

How to Identify: No cool air at all, compressor not running properly, warm compressor area.

Part: Compressor/cooling system
