I'm sorry to hear about your refrigerator troubles. If your LG refrigerator has stopped cooling but is still making noises, there are a few steps you can take to troubleshoot the issue before calling for professional help:
Check the power supply: Ensure that the refrigerator is receiving power correctly. Plug it into a working electrical outlet, and if you have a circuit breaker, make sure it hasn't tripped.
Inspect the temperature settings: Double-check the temperature settings inside the fridge and freezer compartments. Sometimes, the settings might have been accidentally adjusted, causing the cooling to be less effective.
Clean the condenser coils: Dust and debris can accumulate on the condenser coils at the back or bottom of the refrigerator, reducing its cooling efficiency. Unplug the fridge and gently clean the coils with a brush or vacuum cleaner.
Ensure proper ventilation: Make sure the refrigerator has enough space around it for proper ventilation. Overheating due to lack of ventilation can cause cooling issues.
Check the door seals/gaskets: Inspect the rubber door seals to ensure they are not damaged or dirty. If they are not sealing properly, warm air can enter the refrigerator, affecting its cooling capability.
Defrost the freezer: If your fridge has a separate freezer compartment and it's not cooling, it's possible that it has frosted over. Unplug the refrigerator and let it defrost for a few hours. Then, plug it back in and see if the cooling improves.
If after trying these steps, your refrigerator still doesn't cool properly, it may be a more significant problem that requires professional repair. Since your refrigerator is only five years old, it's possible that it could be covered under the manufacturer's warranty or an extended warranty if you purchased one.
Contact LG customer support or a certified technician to diagnose and repair the issue. They will have the expertise and necessary tools to identify the problem and recommend the best course of action to fix it.
