The single most common problem reported across consumer reviews and appliance repair channels for LG refrigerators centers on linear compressor malfunctions, where the cooling system suddenly fails to pump refrigerant, leading to rising internal temperatures while the appliance's exterior lights and evaporator fans continue running normally. Other frequent maintenance concerns include ice maker freezing or jamming due to moisture leakage around the ice compartment, and water pooling at the bottom of the fresh food storage bins because of clogged defrost drain channels. While routine coil cleaning and LG's newer engineering revisions help mitigate these issues, cooling system failures represent the primary historical pain point discussed by technicians.
