Inspect the dryer vent to ensure it is clear of lint and debris. When lint accumulates in the dryer vent and restricts airflow, the dryer is unable to circulate air.
Check the LG dryer power breaker at the lighting panel, when your unit will not start. Generally, an electrical disruption such as a faulty fuse or breaker is the culprit. Inspect the power plug at the outlet to ensure it is plugged in completely.
Inspect the inside face of the door, and remove any lint buildup around the door's seal that may prevent it from closing completely. If the door switch does not make contact when the dryer door is shut, the safety interlock will prevent the dryer from starting.
Adjust the dryer's feet, and make it level, if it's making noise, or shaking while operating. Dryer feet are located at each corner of the machine. Screwing the feet clockwise will lower that corner of the dryer. Screwing the feet counterclockwise will raise the respective corner.
