In this article, we’ll explain the most frequent reasons your refrigerator stops cooling and what you can do before calling a professional technician.
Common Reasons Your Refrigerator Isn’t Cooling
Common Reasons Your Refrigerator Isn’t Cooling
1. Dirty Condenser Coils
1. Dirty Condenser Coils
Condenser coils release heat from your refrigerator. Over time, dust and dirt build up on these coils, causing the system to work harder and cool less efficiently.
If the coils are clogged, your fridge may:
Feel warm inside
Run constantly
Make louder than usual noises
Cleaning the coils once every 6–12 months can prevent this issue.

2. Blocked Air Vents
2. Blocked Air Vents
Cold air needs to circulate freely between the freezer and fridge compartments. When air vents are blocked by food containers or frozen ice, cooling becomes uneven.
Signs of blocked airflow:
• One section cold, another warm
• Ice buildup near vents
• Weak air circulation
Make sure vents aren’t covered by large items.

3. Faulty Evaporator Fan
3. Faulty Evaporator Fan
The evaporator fan pushes cold air throughout the refrigerator. If the fan stops working, the freezer may stay cold while the fridge section becomes warm.
You may notice:
• Strange buzzing or humming sounds
• Warm refrigerator area
• Ice buildup in the freezer
This problem usually requires professional repair.

4. Broken Thermostat
4. Broken Thermostat
The thermostat controls the temperature of your refrigerator. If it fails, the compressor won’t start at the right time, and cooling becomes inconsistent.
Symptoms include:
• Fluctuating temperatures
• Food freezing in the fridge
• Fridge not cooling at all
A faulty thermostat typically needs replacement.
