Frequently Asked Questions
Why is my LG dryer not starting even after pressing the power button?
Ensure the dryer is plugged in properly and the circuit breaker hasn't tripped. Check if the door is fully closed, as the dryer won't start if the door isn't securely latched. Also, verify if the control lock feature is activated, which can prevent the dryer from starting.
What should I do if my LG dryer is not drying clothes evenly?
Clean the lint filter and vent hose to ensure proper airflow. Overloading the dryer can also cause uneven drying; try reducing the load size. Additionally, check for any obstructions in the vent duct that may restrict airflow and consider cleaning the moisture sensors if your model has them.
My LG dryer is making loud noises during operation. How can I fix this?
Loud noises can be caused by loose drum rollers, worn drum bearings, or objects caught in the drum or blower wheel. Inspect and replace any damaged parts. Also, make sure the dryer is level to prevent vibrations and noise during operation.
Why does my LG dryer keep stopping mid-cycle?
This could be due to overheating, a faulty door switch, or a problem with the thermal fuse. Check for lint buildup or blockages in the vent system, which can cause overheating. If the thermal fuse is blown, it will need to be replaced to restore proper operation.
How can I resolve an LG dryer that displays an error code?
Refer to your user manual to identify the specific error code. Common solutions include resetting the dryer by unplugging it for a few minutes, ensuring proper door closure, and clearing lint or obstructions. If the error persists, contacting LG customer service or a professional technician is recommended.
