Why does my LG dryer smell like it's burning?

When an LG electric or gas clothes dryer emits a distinct burning smell during operation, it is typically caused by thick lint accumulation caked directly around the heating element housing, a restricted or clogged exterior exhaust vent duct trapping extreme heat inside the drum, a slipping drive belt, or an overloaded motor. LG dryers feature sensitive electronic safety systems, but mechanical lint buildup remains a manual maintenance responsibility. You can troubleshoot burning odors safely by unplugging the unit and inspecting the internal heating compartment. You can verify that your corrective action is successful when thoroughly vacuuming all trapped lint out of the heating box, cleaning the exhaust duct, and ensuring unrestricted outdoor airflow eliminates the burning smell permanently.
