Today, we will be discussing how to fix a refrigerator that is not cooling. This common problem can be caused by a variety of issues, but with some troubleshooting and basic repairs, you may be able to get your fridge back up and running in no time. Let’s dive into the steps you can take to diagnose and fix the issue.
Understanding the Basics of Refrigerators
Before delving into the specifics of refrigerator repair, it’s important to understand how refrigerators work. A refrigerator works by removing heat from inside the unit and transferring it outside. This process is achieved through a system of coils, compressors, and refrigerants. The refrigerant is responsible for absorbing the heat inside the fridge and transferring it to the coils located at the back of the unit. The compressor then compresses the refrigerant, raising its temperature and pressure. The refrigerant then releases the heat it absorbed to the outside of the fridge, and the cycle starts again.
Common Issues That Cause a Refrigerator to Stop Cooling
There are several reasons why a refrigerator may stop cooling. Some of the most common include:
- Dirty condenser coils
- Faulty compressor
- Low refrigerant levels
- Blocked vents
- Broken thermostat
- Malfunctioning evaporator fan
Troubleshooting a Refrigerator That Is Not Cooling
If your refrigerator is not cooling, there are several steps you can take to troubleshoot the issue. The first thing you should do is check the temperature settings. If the temperature settings are too high, the refrigerator will not cool properly. Make sure that the temperature is set to the recommended level.

Check the Condenser Coils
Dirty condenser coils can also cause a refrigerator to stop cooling. The coils are located at the back of the unit and can become clogged with dust and debris over time. To clean the coils, unplug the refrigerator and use a vacuum cleaner or a condenser coil brush to remove any accumulated dirt or debris.
Check the Evaporator Fan
The evaporator fan is responsible for circulating cold air throughout the refrigerator. If the fan is not working, the refrigerator will not cool properly. To check the fan, open the freezer and listen for the sound of the fan. If it is not running, you may need to replace it.
Check the Thermostat
The thermostat is responsible for regulating the temperature inside the refrigerator. If it is not working properly, the refrigerator may not cool properly. To check the thermostat, turn it to the highest setting and listen for a clicking sound. If you do not hear the sound, you may need to replace the thermostat.
Check the Compressor
The compressor is the heart of the refrigerator’s cooling system. If it is not working properly, the refrigerator will not cool. To check the compressor, unplug the refrigerator and listen for a humming sound. If you do not hear anything, the compressor may be faulty and will need to be replaced.
Check the Refrigerant Levels
Low refrigerant levels can also cause a refrigerator to stop cooling. To check the refrigerant levels, you will need to call a professional to come and check the system. If the levels are low, the technician will need to add more refrigerant to the system.

FAQs – How to Fix a Refrigerator That Is Not Cooling
What are the common causes of a refrigerator not cooling?
A refrigerator not cooling can be caused by a variety of issues, including a malfunctioning compressor, dirty condenser coils, faulty thermostat, or a refrigerant leak. It’s also possible that the temperature control settings have been accidentally adjusted, preventing the refrigeration unit from cooling properly.
How can I troubleshoot a refrigerator not cooling?
There are several steps you can take to troubleshoot your refrigerator when it’s not cooling. Start by checking the temperature control settings, making sure that they haven’t been inadvertently adjusted. If they are set correctly, see if the condenser coils are dirty or blocked, which could prevent adequate airflow. Check for any signs of damage to the door gasket, as a loose seal could also cause cooling issues. Finally, if none of these steps work, it may be best to call in a professional repair service to diagnose and fix the issue.
How do I clean the condenser coils?
Cleaning the condenser coils is an important maintenance task that can help ensure your refrigerator runs efficiently. First, locate the coils, which are typically located behind a grille on the back or bottom of the unit. Use a soft brush or vacuum attachment to gently remove any dust, dirt or debris. You can also purchase a coil cleaning brush to make the job easier. Be careful not to use any chemicals or harsh cleaning agents, which can damage the coils.
How can I tell if there is a refrigerant leak in my refrigerator?
If your refrigerator isn’t cooling properly and you suspect a refrigerant leak, there are a few signs to look for. First, check the temperature settings to see if they have been inadvertently adjusted. If the temperature is still warm, listen for any hissing or bubbling sounds, which could indicate a refrigerant leak. You may also notice that there is frost buildup on the evaporator coils, which is another sign of a refrigerant leak. In this case, it’s best to call a professional refrigeration repair service to diagnose and fix the issue.

Can I fix a refrigerator not cooling on my own?
While there are certain maintenance tasks you can do on your own, such as cleaning the condenser coils, it’s best to leave major repairs to a professional. Refrigerators are complex machines that require specialized knowledge and tools to fix, and attempting to repair them on your own can often lead to further damage or injury. If your refrigerator is not cooling, it’s best to call in a professional repair service to diagnose and fix the issue.
