Common problems with LG dryers include failure to heat up, dryer becoming too hot, production of unusual noise and the dryer stopping during a cycle. Other issues include the dryer taking too long and failure to start or stop properly.
LG dryers fail to heat up if the thermal fuse is defective. This is caused by overheating of the thermal fuse. When there is a defective igniter or a faulty gas valve solenoid, the dryer fails to heat up. A defective heating element causes the dryer to become too hot. This produces heat, regardless of whether the appliance requires heat or not. Air flow problems due to lack of good ventilation cause this issue. This clogs the air flow system preventing the entry of fresh air.
If the LG dryer makes unusual noises, the drive belt may be frayed. The damaged belt makes noise as it rotates around the pulleys. Defects in the motor system cause the LG dryer to stop turning during a cycle. This prevents the drum and the blower wheel from exhausting the air inside the dryer. A clogged ventilation system causes the dryer to take too long to dry because of the reduction in air flow. LG dryers develop problems in starting or stopping if the thermal fuse is defective.
