1. Faulty thermostat: The thermostat is the device that controls the temperature inside the refrigerator. If the thermostat malfunctions, the refrigerator will not be able to regulate the temperature of the freezer compartment. Check if the thermostat is damaged or needs to be replaced.
2. Fan failure: the function of the fan is to circulate cold air inside the refrigerator. If the fan malfunctions, the cold air will not be evenly distributed to every corner of the refrigerator, thus causing the temperature of the freezer to become unstable. Check if the fan is working properly and replace it if it is found to be faulty.
3. Heat pipe blockage: The heat pipe of the refrigerator plays a role in circulating refrigerant to the radiator. If the heat pipes are clogged with dirt or other substances, the refrigerant will not be able to flow. This will result in the refrigerator not cooling. This situation may require contacting a professional technician for inspection and repair.
4. Refrigerant Leak: Refrigerant is the key component that causes the refrigerator to be able to cool. If the refrigerant leaks, the refrigerator will not be able to cool. In this case you need to contact a professional technician to check the problem and replace the refrigerant as necessary.
5. Poor door seal: If the door of the refrigerator is not sealed properly, cold air will leak out through the cracks in the door, which will prevent the freezer from maintaining the correct temperature. Check that the door seal is intact and proceed to replace the part that needs to be replaced.
In conclusion, if you notice that the freezer compartment of your Upper Lynch refrigerator is not cooling, it is important to note that if the problem is serious, it is best not to fix it on your own, but consider contacting a professional for inspection and repair. This will help you minimize the damage and ensure that your refrigerator will be back to its normal working condition in the shortest possible time.
