There could be several reasons why your LG refrigerator's compressor runs for a while and then stops, resulting in temperature imbalances between the freezer and refrigerator sections. Here are a few possible explanations:
Thermostat issue: The thermostat in your refrigerator controls the compressor's operation based on the temperature settings you've selected. If the thermostat is faulty or incorrectly calibrated, it may cause the compressor to cycle on and off irregularly. This can lead to temperature fluctuations in the refrigerator compartment.
Condenser or evaporator fan problems: The condenser fan and evaporator fan in your refrigerator help circulate air and regulate temperatures. If either of these fans is malfunctioning or not operating optimally, it can impact the cooling efficiency and result in uneven temperature distribution.
Faulty defrost system: Refrigerators are equipped with a defrost system that periodically removes frost buildup from the evaporator coils. If the defrost system is faulty, frost can accumulate and obstruct the airflow, leading to inadequate cooling in the refrigerator section.
Insufficient airflow: Ensure that there are no obstructions blocking the vents inside the refrigerator. Blocked vents can impede the airflow and prevent proper cooling in the refrigerator compartment.
Compressor issue: While less common, a problem with the compressor itself could also cause irregular operation. Issues like overheating, electrical faults, or mechanical failures may result in the compressor shutting off prematurely.
To troubleshoot and resolve the issue, you can try the following steps:
Check the temperature settings: Ensure that the temperature settings are correctly set for both the freezer and refrigerator compartments.
Clean the condenser coils: Dust and debris buildup on the condenser coils can affect cooling efficiency. Clean the coils located either at the back or beneath the refrigerator, following the manufacturer's instructions.
Verify proper ventilation: Make sure there is adequate space around the refrigerator for proper airflow. Remove any items that may be blocking the vents.
If these steps do not resolve the issue, it is recommended to contact LG customer support or a professional appliance repair technician to diagnose and fix the specific problem with your refrigerator.
