Why Is My Fridge Freezing on One Side Only?
Many homeowners may encounter a frustrating issue where the cooling plate of their fridge's lower compartment is only partially covered with ice, while the freezer section remains perfectly functional. This article aims to shed light on the probable cause and provide guidance on how to address this problem effectively.
The Probability of a Low Refrigerant Issue
One of the most common reasons for your fridge’s cooling plate being partially covered with ice is a potential issue with the refrigerant level. If the refrigerant in your fridge is low, the pressure inside the system may run too low. This can cause the coil on the lower compartment to freeze over, significantly reducing heat transfer efficiency. The ice acts as an insulator, greatly minimizing the effectiveness of the cooling process. As a result, only the side where the coils are frozen is unable to chill properly.
Hard Installations of Frost Instead of Frost Free
Several types of refrigerators use a 'Not Frost Free' system, meaning ice needs to be removed periodically. If the ice on your fridge's coils is not taken care of, it can impede the overall cooling efficiency. This system relies on manual defrost to maintain optimal cooling performance. Therefore, removing the ice from the coils in the lower compartment will restore the fan and evaporator effectiveness, allowing for better heat exchange. Without freeing the coils, the cooling plate will continue to be covered with ice, reducing cooling efficiency.
Steps to Troubleshoot and Resolve the Issue
Check the Refrigerant Level
To diagnose whether the low refrigerant is causing this issue, you can check the refrigerant level using a pressure gauge or consult a professional technician. Ensure that your fridge is properly sealed and functioning before conducting these checks. If the refrigerant is indeed low, it may require professional intervention to recharge the system. Diagnosing and repairing a refrigerant leak can be complicated and should only be conducted by a certified technician.
Perform Regular Defrost
If you have a non-frost-free refrigerator, regularly scheduled defrosting is a necessity. Disconnect the fridge, defrost the coils, and then reconnect the power supply. Make sure to do this in a well-ventilated area to avoid inhaling any harmful gases. It’s also essential to ensure that the fridge is in a location with proper airflow, as obstructions can lead to poor cooling performance.
Inspect and Clean the Coils
Occasionally, dust or debris can accumulate on the fridge's evaporator coils, hindering their efficiency. Use a soft cloth or a vacuum cleaner with a brush attachment to clean the coils. Do this even if the coils are covered with ice, as clearing the dust can help improve cooling performance. Be careful not to damage the coils during the cleaning process.
Conclusion
The issue of partial ice coverage on the lower compartment cooling plate can be attributed to a variety of factors, the most common being an insufficient refrigerant level. By regularly checking the refrigerant level in your fridge, ensuring proper defrosting for non-frost-free models, and keeping the coils clean, you can significantly improve the cooling efficiency of your appliance. If the problem persists, it's best to consult a professional technician to ensure the issue is resolved effectively and safely.
