The various troubleshooting methods you can use to resolve the issue of the LG dryer not heating will be discussed in this section of the article.

Check that the Dryer is not Overloaded.

Before attempting any other troubleshooting method, you need to confirm that you are not loading the dryer above its capacity for a single cycle.

You should ideally only fill about 3/4 of the dryer with wet clothes that need to be dried, and this is because when the dryer is fully loaded with clothes, air will not circulate properly in the dryer. This limited airflow will make the dryer take longer than necessary to dry the clothes and, in extreme cases, will be unable to dry the clothes at all.

To prevent the issue of limited airflow in the dryer, only fill 3/4 of the dryer capacity with clothes so that air can circulate properly in the dryer, and you will have your clothes dried in little to no time.

Clean Clogged Dryer Vent

The LG dryer has a lint vent at the bottom of the door to store the debris and other particles in the dryer, and when this vent becomes clogged, it can become the reason for the LG dryer not heating as it would obstruct airflow in the dryer.

Follow the instructions below to clean your clogged dryer vent.

  • Turn off the dryer and move it away from the wall.
  • Then unplug it from its power source and disconnect the duct to access the connection between the wall and the dryer.
  • Clean the insides between the wall and the dryer of visible debris and dust.
  • Then use a dryer brush to remove the debris inside the duct.
  • Then connect the duct back to the dryer and turn on the dryer.

You can then use the dryer to dry your clothes to confirm that you have resolved the issue of the LG dryer not heating.

Check the Thermal Fuse

The thermal fuse is an essential safety device in the dryer that protects the critical parts of the dryer when the dryer overheats.

The thermal fuse blows up when the dryer overheats to protect the parts of the dryer. When the thermal fuse is blown or defective, it will prevent the LG dryer from heating, causing your clothes to stay wet, even after a long time in the dryer.

If you suspect that the thermal fuse in your dryer is blown, you should engage the service of a professional to find out why and replace it for you.

Do not attempt to replace the thermal fuse yourself, as you might end up damaging the dryer and harming yourself.

Check the Heating Element

The heating element consists of different wires that produce heat for the dryer when they receive electric current, so if any of the wires get burnt, the dryer will be unable to produce heat, resulting in the issue of the LG dryer not heating.

If you think this is the cause of your dryer not heating, reach out to a professional for assistance in replacing it.

Check the Cycling Thermostat

The cycling thermostat in the dryer regulates the air temperature by turning the heat on and off as needed. If the cycling thermostat becomes faulty, the dryer will be unable to produce the necessary heat to dry your clothes.

If the thermostat becomes defective, the only option is to get a replacement.

Check the Flame Sensor

If you use an LG gas dryer, you need to check that the flame sensor is working perfectly, as the flame sensor detects the heat emitted by flames and triggers the igniters.

If it is malfunctioning, it will be unable to trigger the igniter, and the dry will be unable to dry your clothes.

You can use a multimeter to check the flame sensor, and if there is no continuity, you would have to get it replaced.

Check the Igniter

If you use an LG gas dryer, it is essential that you check the igniter when you have a situation of your LG dryer not heating because the igniter ignites the gas in the burner assembly to produce the hot air used in drying.

When it is faulty, it would be unable to trigger the burner, and the dryer would be unable to produce the heat required to dry your clothes.

You should use a multimeter to confirm if it is defective; if it is, you would need to get a professional to help you replace it.
