A refrigerator that isn’t cooling properly can be a significant inconvenience, potentially leading to spoiled food and unexpected expenses. Understanding why your fridge isn’t maintaining the right temperature is the first step toward resolving the issue. At Machine Repair Nairobi, we’ve encountered and repaired countless cooling problems, and in this informative article, we’ll explain the common causes and provide expert repair tips to help you troubleshoot or decide when to call a professional.

Common Reasons Your Fridge Isn’t Cooling

When your fridge fails to cool, several components or conditions could be at fault. Below, we outline the most frequent culprits and their symptoms.

1. Dirty Condenser Coils

The condenser coils, located at the back or beneath your fridge, dissipate heat. If they’re covered in dust or grime, the fridge can’t release heat effectively, causing poor cooling.

• Signs: Warm fridge interior, compressor running hot.
• Tip: Unplug the fridge and clean the coils with a brush or vacuum every six months.

2. Faulty Evaporator Fan

The evaporator fan circulates cold air inside the fridge and freezer. If it stops working, air doesn’t move, and cooling becomes uneven or stops entirely.

• Signs: No air movement, freezer cold but fridge warm.
• Tip: Listen for the fan’s hum. If silent, it may need replacement—contact a technician.

3. Blocked Air Vents

Overloading your fridge or placing items too close to the vents can obstruct airflow, preventing proper cooling.

• Signs: Uneven temperatures, some areas warmer than others.
• Tip: Rearrange contents to ensure vents (usually at the back or top) are clear.

4. Low Refrigerant Levels

Refrigerant is the substance that cools the air in your fridge. A leak or depletion reduces its ability to absorb heat.

• Signs: Hiss or bubbling sounds, consistent warmth despite running.
• Tip: This requires professional attention to locate leaks and recharge the system.

5. Malfunctioning Thermostat

The thermostat regulates the fridge’s temperature. If it’s faulty, it may not signal the compressor to start cooling.

• Signs: Temperature too high or too low, inconsistent cooling cycles.
• Tip: Test by adjusting the dial—if no change occurs, it may need recalibration or replacement.

Step-by-Step Troubleshooting Guide

Before calling for repairs, try these expert steps from Machine Repair Nairobi to diagnose the issue:

1. Check the Temperature Settings
   Ensure the fridge is set to 3-5°C and the freezer to -18°C. Wait 24 hours after adjusting to assess cooling.
2. Inspect the Power Supply
   Verify the fridge is plugged in securely and the outlet works. A tripped breaker could be the problem.
3. Examine the Door Seals
   Worn or loose gaskets let warm air in, forcing the fridge to overwork. Test by closing the door on a piece of paper—if it pulls out easily, the seal needs replacing.
4. Listen to the Compressor
   The compressor (a black box at the back) should hum quietly. If it’s silent or clicking repeatedly, it might be failing.
5. Assess Airflow
   Feel for cold air from the vents. If absent, check the fan or clear any blockages.

If these steps don’t resolve the issue, professional expertise may be required to avoid further damage.
