Why is refrigerator working but freezer not freezing?


When your refrigerator is working fine, but the freezer fails to freeze properly, it can be a frustrating experience. Understanding the reasons behind this issue can help you troubleshoot and resolve the problem effectively. In this article, we will explore some common causes for a refrigerator working but the freezer not freezing.

Thermostat Issues

Thermostat malfunction: One possible reason for a freezer not freezing is a malfunctioning thermostat. The thermostat controls the temperature inside the freezer, and if it is not functioning correctly, it may not signal the freezer to cool down adequately. In such cases, the refrigerator may still work fine, but the freezer will not reach the desired freezing temperature.

Defective Evaporator Fan

Blocked or malfunctioning evaporator fan: The evaporator fan is responsible for circulating the cold air throughout the freezer. If it becomes blocked by ice or debris, or if it malfunctions, the freezer will not cool properly. As a result, the refrigerator may continue to work, but the freezer will not freeze as expected.

Condenser Coils

Dirty or damaged condenser coils: Condenser coils play a crucial role in removing heat from the freezer. If they are dirty or damaged, they may not be able to release heat effectively, leading to inadequate cooling in the freezer. Regular cleaning and proper maintenance of the condenser coils can help prevent this issue.

Seal and Gasket Problems

Worn-out door seal or gasket: The door seal or gasket ensures a tight seal when the freezer door is closed. If it becomes worn out or damaged, cold air can escape from the freezer, resulting in insufficient cooling. Inspect the seal or gasket for any signs of wear and tear, and replace it if necessary.

Insufficient Airflow

Blocked vents or airflow restrictions: In some cases, the freezer may not freeze properly due to blocked vents or airflow restrictions. Check for any obstructions that may be preventing proper airflow, such as food items placed too close to the vents. Clearing any blockages can help restore proper cooling in the freezer.

Refrigerant Leak

Refrigerant leak: A refrigerant leak can also lead to a freezer not freezing adequately. The refrigerant is responsible for absorbing heat from the freezer, and if there is a leak, the cooling process will be compromised. If you suspect a refrigerant leak, it is best to consult a professional technician to identify and fix the issue.


In conclusion, a refrigerator working but the freezer not freezing can be caused by various factors. These include thermostat issues, a defective evaporator fan, dirty or damaged condenser coils, seal and gasket problems, insufficient airflow, or a refrigerant leak. By understanding these potential causes, you can troubleshoot the problem and seek appropriate solutions to restore proper freezing in your freezer.
