If your fridge is switched on but not cooling properly, the problem could be caused by incorrect temperature settings, a faulty door seal, dirty condenser coils, a fan issue, defrost problems, low refrigerant gas or compressor failure. This guide explains the
A fridge that is not cooling properly can quickly become a serious problem in any London home. Food may start to spoil, unpleasant smells can appear, and the appliance may begin working harder than normal. If your fridge is switched on but does not feel cold enough, it is important to find the cause before the problem becomes worse.
Common Reasons Why Your Fridge Is Not Cooling
When a fridge stops cooling, it does not always mean the appliance has completely failed. Sometimes the cause is simple, such as incorrect temperature settings, a door that is not closing properly, dirty condenser coils, or an overfilled fridge. In other cases, the issue may be linked to important parts such as the fan, thermostat, defrost system, refrigerant gas, or compressor.

A fridge that is not cooling properly can lead to spoiled food and extra pressure on the appliance.
1. Incorrect Fridge Temperature Settings
One of the simplest reasons why your fridge is not cooling is an incorrect temperature setting. The dial or digital control may have been changed accidentally, or the fridge may have been set too warm. If you have recently adjusted the temperature, allow the appliance a few hours to reach the new setting.
If it still does not cool properly after a few hours, the issue may be linked to another part of the appliance.
2. The Fridge Door Is Not Closing Properly
If the fridge door does not close fully, cold air can escape and warm air can enter the appliance. This can happen because of a damaged door seal, dirt around the seal, an uneven fridge position, or food containers blocking the door.
Check the rubber door seal carefully. If it is loose, cracked, dirty, or no longer sealing properly, your fridge may struggle to maintain the correct temperature.
3. Dirty Condenser Coils
Condenser coils help release heat from the fridge. If they become covered with dust, pet hair, grease, or dirt, the fridge may need to work harder to cool the inside. This can reduce cooling performance and may increase strain on the appliance.
In many fridges, the condenser coils are located at the back or underneath the unit. Cleaning this area can help improve performance, but it should be done carefully to avoid damaging any components.
A door that does not close properly can allow cold air to escape and affect fridge cooling.
4. Faulty Fridge Fan
The fridge fan helps circulate cold air inside the appliance. If the fan stops working or becomes faulty, the freezer may still feel cold while the fridge section stays warm. Unusual noises, a lack of normal fan sound, or uneven cooling can all point to a fan problem.
5. The Fridge Is Too Full
If the fridge is packed too tightly, cold air may not circulate properly. Some areas may remain cool while others stay warmer than they should. Try to avoid blocking the air vents and leave enough space between items so cold air can move around the fridge.
6. Faulty Thermostat or Temperature Sensor
The thermostat or temperature sensor helps the fridge detect the internal temperature and control the cooling system. If this part is faulty, the fridge may be switched on but may not cool correctly because it is reading the temperature incorrectly.
7. Defrost System Problems
If the defrost system is not working properly, ice can build up inside the appliance and block the airflow. This can stop cold air from reaching the fridge section, especially when the freezer seems cold but the fridge stays warm.
Good food placement inside the fridge helps cold air circulate more effectively.
8. Low Refrigerant Gas or a Leak
Refrigerant gas plays an important role in the cooling process. If the gas level is low or there is a leak, the fridge may not be able to cool properly. This type of problem usually requires professional inspection and should not be handled without the correct tools and experience.
9. Compressor Problems
The compressor is one of the most important parts of the fridge cooling system. If the compressor is not working correctly, the appliance may not be able to cool at all. Clicking sounds, frequent starting and stopping, a warm fridge interior, or the fridge running for long periods can all be signs of a compressor issue.
What Should You Check Before Calling a Technician?
- Make sure the fridge is plugged in and switched on.
- Check the temperature setting.
- Make sure the fridge and freezer doors close fully.
- Inspect the door seal for cracks, dirt, or looseness.
- Do not block the internal air vents with food.
- Check the back or bottom of the fridge for dust build-up.
When Should You Book Fridge Repair?
If your fridge is still not cooling after checking the simple causes, it is best to contact a professional appliance repair technician. Continuing to use a fridge that is not cooling properly can put extra pressure on internal parts and may lead to more serious faults.
You should also take the issue seriously if you notice unusual noises, a burning smell, water leaks, heavy ice build-up, or the outside of the fridge becoming unusually hot.
FAQs About a Fridge Not Cooling
Why is my fridge running but not cooling?
The issue could be related to the temperature setting, fan, thermostat, condenser coils, refrigerant gas, or compressor. Start with the simple checks, and if the problem continues, arrange a professional inspection.
Why is my freezer cold but my fridge warm?
This can happen when the fan is faulty, the airflow is blocked, or the defrost system is not working properly. Cold air may not be moving from the freezer section into the fridge section correctly.
Can dirty condenser coils stop a fridge from cooling?
Yes. Dirty condenser coils can stop heat from being released properly, making the fridge work harder and reducing its cooling performance.
Final Thoughts
A fridge that is not cooling can be caused by something simple, such as an incorrect temperature setting or a door that is not closing properly. However, it can also be linked to more serious faults involving the fan, thermostat, defrost system, refrigerant gas, or compressor. If the basic checks do not solve the problem, professional fridge repair can help prevent further damage.
