Few things are as frustrating as opening your fridge only to find warm milk, soggy vegetables, and spoiled leftovers. If your refrigerator is running but not cooling, it’s not just an inconvenience — it’s a potential food safety hazard.

At Matrix Appliances, we understand how essential your fridge is in your daily life. That’s why we’ve compiled this easy-to-follow guide to help you understand why your fridge may not be cooling properly, and what you can do to fix it.

1. Dirty Condenser Coils

What’s the problem?

Your fridge’s condenser coils (usually located at the back or bottom) are responsible for releasing heat. The system cannot efficiently cool if these coils are dusty or unclean.

Signs:

• Warm refrigerator interior
• Loud or constantly running compressor
• Fridge feels hot on the exterior

Solution:

Unplug the unit and clean the coils using a vacuum or coil brush every 6 months.

2. Faulty Evaporator Fan

What’s the problem?

Cold air is circulated throughout the refrigerator via the evaporator fan. Even if the freezer is operating properly, your refrigerator won't get chilly if it's broken.

Signs:

• The refrigerator is warm, while the freezer is frigid.
• Unusual noise or complete silence from the fan area
• Frost buildup on the freezer coils

Solution:

Check the fan inside the freezer section. If it's not spinning, call Matrix Appliances to replace the motor or fan blade.

3. Thermostat or Temperature Control Issues

What’s the problem?

A malfunctioning thermostat means your fridge doesn’t know when to cool. This results in either overcooling or no cooling at all.

Signs:

• Temperature fluctuates without reason
• Display panel errors or stuck readings
• No humming or sound from compressor

Solution:

Try adjusting the thermostat to a colder setting. If nothing changes, the sensor or control board may need repair by a technician.

4. Blocked Air Vents

What’s the problem?

Your fridge relies on unobstructed air circulation. Overloading shelves or blocking vents with containers can block airflow and reduce cooling efficiency.

Signs:

• The top shelf is warm, while the bottom shelf is frigide.
• Ice buildup around vents
• Condensation inside the fridge

Solution:

Reorganize the fridge. Keep vents clear and ensure items don’t touch the rear walls.

5. Compressor Failure

What’s the problem?

The primary component of your refrigerator's cooling system is the compressor. Your refrigerator isn't cooling if it isn't operating or is just making clicking noises.

Signs:

• No humming or vibration at the back
• Fridge is completely warm
• Clicking sound every few minutes

Solution:

A compressor issue is not a DIY fix. Contact Matrix Appliances immediately for professional diagnosis and replacement if needed.

6. Start Relay or Capacitor Malfunction

What’s the problem?

These components help start the compressor. If either fails, the compressor won’t kick in, and the fridge won’t cool.

Signs:

• After trying to start, the refrigerator shuts off
• Clicking sounds from the compressor
• Burnt smell from behind the unit

Solution:

Only trained technicians should replace electrical components. Call Matrix Appliances for expert service.

7. Door Seal Leaks

What’s the problem?

If the rubber gasket around your fridge door is torn, loose, or dirty, cold air escapes, and the fridge must work harder to maintain temperature.

Signs:

• Door doesn’t shut tightly
• Condensation around the seal
• Fridge constantly running

Solution:

Clean the gasket with warm, soapy water. It should be replaced if it is damaged.

Pro Tips to Keep Your Fridge Running Smoothly

• Clean condenser coils every 6 months
• Don’t overload shelves or block air vents
• Ensure doors close properly every time
• Maintain a refrigerator temperature between 2°C and 5°C
• Don't put hot food in the refrigerator right away
