The Belt is an OEM replacement part for LG dryers that is responsible for connecting the motor to the drum to allow it to tumble. Over time, dryer belts can stretch, wear out, or even break, leading to a drum that won't turn and clothes that don't dry properly. Symptoms of a bad Dryer Belt include: The dryer motor running but the drum not turning. A squealing or thumping noise coming from the dryer. The dryer not starting at all. Causes of failure can include regular wear and tear from the dryer's operation, overloading the dryer beyond its capacity, which puts extra strain on the belt, or a misalignment that causes uneven wear. A damaged belt can prevent your dryer from functioning correctly, leading to inefficiency in drying clothes and potential motor damage due to unnecessary strain. Replacing a faulty or worn-out Dryer Belt helps keep your dryer running smoothly, allowing clothes to dry quickly and evenly. This OEM LG part can also be used on Kenmore/Sears appliances.   This part fixes the following symptomsWill not tumblePart Number 4400EL2001F (AP5972814) replaces 4115028, 4400EL2001C, 4400EL2001E, PS11705916.
