The Dryer Lint Filter is an OEM part for LG dryers. It is designed to capture lint and debris from clothes during the drying cycle, helping to prevent these particles from clogging the dryer vent. This filter is crucial for maintaining the efficiency and safety of your dryer, as a clean lint filter reduces the risk of fires and ensures that the appliance operates at optimal performance levels. Symptoms of a bad Dryer Lint Filter include: Excessive lint accumulation outside the filter area, indicating a tear or hole in the filter. Reduced drying efficiency, with clothes taking longer to dry or feeling damp after a complete cycle. Noticeable wear or damage to the filter, such as fraying or holes. Causes of a bad dryer lint filter can include regular wear and tear from usage, accumulation of fabric softener which can clog the mesh, or physical damage from removing or cleaning the filter improperly. This OEM LG part is also compatible with Sears/Kenmore, ensuring it fits a wide range of dryer models within these brands.Part Number 5231EL1003B (AP4440606) replaces 1266857, 5231EL1002E, 5231EL1003A, 5231EL1003C, 5231EL1003E, AH3527578, EA3527578, PS3527578.
