If your LG dryer is taking too long to dry your clothes or your dryer is not heating properly this is likely due to a blockage to the dryer’s airflow, which will make dry times longer than normal. Airflow blockages can be caused by an obstruction in the duct work or lint build-up on your lint screen. Have the duct work professionally cleaned annually and clean the lint screen after every cycle.
Make sure the moisture sensors are clean and properly sensing.
To check the moisture sensor use Test Mode and a damp cloth and make sure the sensor value on the screen changes when cloth contacts the sensor.
Below is main board connector NA6. It connects to the moisture sensor bars and the temperature sensor thermistor.
Moisture Contet | Display Value | Voltage (Blue to Orange wire) | Remark |
>40% | <130 | < 2VDC | Wet clothes from washing machine |
40% – 20% | 130 – 205 | 2 – 4 VDC | Damp Dry |
<10% | >205 | > 4VDC | Completely dried clothes |
Ensure the washer is spinning out most of the water to avoid having lengthy dry cycles.
Also, make sure the dryer is not being overloaded with clothing to the point it cannot tumble the clothes and dry effectively.
If the customer selects the highest dry level it will cause the dryer to stay on longer. Be sure customer is using the normal dry level option if the complaint is too long of a dry time.
Check that Energy Saver is NOT on. This feature will default in some cycles such as cotton normal and will need to be turned off, (Energy Saver only tumbles, without any heat, for approximately 40 minutes). For faster drying turn off, press and hold the Energy saver button, or Wrinkle Care for over 3 seconds. (On applicable Models).
