LG Dryer Not Heating

LG dryers are particularly susceptible to heating issues due to their high-efficiency design and moisture sensor technology. Unlike traditional dryers, LG units rely heavily on their moisture sensing bars and electronic control boards to regulate heating cycles. When these sensors become coated with fabric softener residue or lint, they can misread moisture levels and prematurely shut off the heating element. LG's Sensor Dry technology, while energy-efficient, creates a complex interaction between the heating element, thermostats, and control board that can fail in cascade fashion.

LG dryers also feature a unique thermal fuse design that's more sensitive than other brands, often triggering at lower temperatures when airflow is restricted. The brand's inverter-driven heating elements in newer models (2018+) are prone to control board communication failures, where the heating element receives power but the inverter module fails to regulate it properly. This is especially common in LG's ultra-large capacity models where the heating demands exceed the inverter's long-term reliability threshold.
