A refrigerator that suddenly stops cooling can be stressful — especially when your food, drinks, and medication rely on proper temperature control.
If your fridge is not cooling, here are the most common reasons, what you can safely check at home, and when it’s time to call a professional fridge repair technician.
Samsung refrigerators are reliable but have several known cooling-related issues. The most common include:
If food items block the vents, cold air cannot circulate.
Signs:
Freezer cold but fridge warm
Inconsistent temperatures
Items freezing in some sections but warm in others
Move items away from vents and ensure good airflow.
The condenser coils dissipate heat. When they become dusty or clogged, cooling efficiency drops significantly.
This is very common in Hamilton homes with pets or older hardwood floors that collect dust.
Fix:
Unplug fridge → pull forward → vacuum and brush coils → restore power.
The evaporator fan pushes cold air through the fridge. If it fails, you’ll notice immediate cooling loss.
Symptoms:
Loud humming or squealing
No airflow from vents
Freezer cold, fridge warm
This requires professional repair.
Samsung models are notorious for evaporator coil frosting issues, which block airflow.
Signs:
Clicking or buzzing sounds
Water dripping inside fridge
Warm fridge but cold freezer
This is typically a defrost system failure.
This is one of the costliest problems and requires certified diagnosis.
Symptoms:
Fridge completely warm
Clicking noise from back
Compressor running hot or not running at all
Sometimes the issue is simple — the temperature was accidentally changed.
Recommended settings:
Fridge: 2–4°C
Try these steps first: Step 1: Check Power & Controls
Make sure the fridge is plugged in, outlet working, and not in “Demo Mode.”
Step 2: Check Door Seals
A bad gasket allows warm air to enter. Inspect for gaps, tears, or dirt buildup.
Step 3: Check for Blocked Vents
Rearrange items to allow airflow.
Step 4: Clean Condenser Coils
Dirty coils are one of the most frequent causes
Step 5: Listen for the Fan
If the compressor is running but no air is flowing, the internal fan may have failed.
Step 6: Check for Ice Build-Up
If the back panel inside the fridge is iced over, you have a defrost system issue.
If none of these help, the problem is likely a component failure.
If your fridge still isn’t cooling, it’s important to get it inspected quickly to avoid food spoilage.
