Why LG Dryer Not Heating Up [Fixed in 2 minutes]

There are various reasons why your dryer may not be heating up.

However, the most common reason behind this issue is a faulty heating element or clogged vent.

If the heating element is faulty or malfunctioning the dryer will still spin but it won’t dry the clothes.

Similarly, if the vent is clogged it will block the airflow resulting in the same problem.

Therefore, if your dryer is not heating up it is recommended to inspect both the vent and the heating element for faulty.

Besides, a blown thermal fuse and overloading can also result in heating-up issues in LG dryers.

How to troubleshoot this problem?

To troubleshoot this problem first we must inspect some components of the dryer. The LG dryer not heating up issue is triggered due to a defective component

. More specifically a faulty heating element can result in heating issues in your dryer.

In this section, we will look at a couple of reasons and their fix to troubleshoot this problem from your dryer.

1.Faulty heating element

A faulty heating element is very likely to cause heating issues in the dryer.

As we know that the main function of the heating element is to heat the air inside the dryer drum.

It is installed inside the housing and as the air passes from the blower it will heat the air.

This air causes water to evaporate from the clothes. Similarly, if the heating element is defective your dryer drums will spin but the clothes will remain wet.


It is possible that the heating element inside your dryer may be malfunctioning. Therefore, I suggest you inspect the heating element inside the dryer.

A defective heating element doesn’t show up continuity.

If you have a multimeter you can conduct a continuity test on the heating element. Here is the step-wise instruction on how you can do a continuity test on the heating element.

  1. Unplug the power cords from the outlet or flip the circuit breaker.
  2. If you have kept the dryer inside the cabinet remove it first. Similarly, if your dryer isn’t inside the cabinet pull the dryer away from the wall.
  3. Now locate the upper panel and all the screws that secure them. Remove all the screws securing the upper panel and keep the panel aside.
  4. Now open the door and remove the screw that secures the door access panel. And, remove all the screws securing the front access panel.
  5. After removing the front access panel again you need to remove the bulkhead from the dryer. However, before removing the bulkhead I suggest you disconnect all the wires connected to the bulkhead or sensor.
  6. Depending upon the model on the left side you will see a blower and on the right side, you will see the heating compartment of your LG dryer.
  7. Disconnect the wires connected to the heating compartment.
  8. Set your multimeter into continuity settings and place one of each probe in the heating compartment wire terminal.
  9. If the heating element is functional you will see significant changes in meter reading with a beeping sound. Similarly, if the heating element is defective there will be no significant change in meter reading and doesn’t produce a beeping sound.

This is how you can test the continuity of the heating element. If the above test fails to show continuity I suggest you consult with technicians and consider getting a heating element replacement.

2.Clogged vent or lint filter

A clogged vent or lint filter is another common reason behind the LG dryer not heating up issue. A lint filter is designed to trap lint that is naturally pulled out from the clothes.

During drying operation, it is very common for clothes to release lint.

However, this lint can gather up in an important place which can later cause a problem during the cleaning.

Therefore, to prevent this there is a dedicated lint filter that traps all the dirt and lint after the drying operation.

Over time the lint filter can clog which can block the air circulation inside the drum.

This can result in LG dryer not heating up problems afterwards. Therefore, consider cleaning the lint filter of your dryer.


To maintain a smooth and flawless performance you should always maintain cleanliness inside the dryer.

A clogged vent or lint filter is also the reason behind the fire mishap inside the dryer.

The process is quick and easy you can easily access the lint filter on your dryer. Here is how you can clean the lint filter of the LG dryer.

  1. First of all unplug the power cables from the power outlet.
  2. Now open the dryer’s door.
  3. Just beside the door you will find a lint filter trap. It is locked with a tab. Depress the tab and pull the lint filter up. You can take the owner’s manual reference for info about the lint trap.
  4. Now clean the lint filter using a soft brush and with your fingers. For the remaining lint filter sink the filter under warm water and dish soap. After a couple of minutes, all the dirt remaining will loosen from the filter.
  5. Gently start scrubbing the filter and clean all the dirt that remains.
  6. Rinse the filter under the running water and leave it to dry before reinstalling.

This is how you can clean the lint filter of the LG dryer. After cleaning the lint filter I suggest you clean the blower and dryer vent as well. If you don’t know follow the below instructions.

  1. Remove the upper and front access panels. And, also remove the bulkhead from the dryer. (Follow the faulty heating element step-wise instruction to remove the panel)
  2. Now in the bottom left corner you will see the blower. In some models, it may be secured with the panel. If it is secured with a panel I suggest you remove the panel first.
  3. Now inspect inside the blower and clean the dirt and lint if present. After cleaning the blower start cleaning the dryer exhaust hose.
  4. Pull the dryer away from the wall and remove the metal clip securing the exhaust hose.
  5. After removing the metal clip pull the hose out. Now using a vacuum suck all the dirt and lint filter inside the dryer exhaust hose.

Reinstall all the components that you’ve removed during the process and restart the dryer. Run a normal cycle and see if the dryer is heating or not.

3.Blown thermal fuse

A blown thermal switch is another reason which can trigger heating issues in the dryer. The thermal fuse is a safety switch that monitors the temperature inside the dryer.

If the temperature exceeds a certain limit the switch will blow. To prevent any kind of mishap associated with heating.

Once the switch is blown off it will disconnect the control panel. This will shut off all the functioning of the dryer including the heating.


If the above-discussed solution didn’t fix the heating issue check the thermal switch of the dryer.

It is located near the blower housing or heating compartment.

You can do a continuity test to identify if the switch is blown up or not. Here is the step-wise instruction to conduct a continuity test on the thermal switch.

  1. Turn off the dryer power supply or flip the circuit breaker. And, make sure that the drum is empty.
  2. Open the door and unthread the screw securing the front access panel of the dryer.
  3. After removing the front access panel you will also need to remove the bulkhead. Disconnect the wire, and sensor and remove the bulkhead from the dryer.
  4. Now locate the thermal fuse. In some models, it is located beside the heating compartment. Similarly, it could also be located around the blower.
  5. Disconnect the wire connected to the fuse.
  6. Set your multimeter into the continuity test. And, place both probes on the fuse wire terminal.
  7. If the thermal switch has a continuity multimeter will show a significant change in the meter readings and also makes a beeping sound. A blown thermal switch won’t have any significant change on the meter display and also doesn’t make a beeping sound.

This is how you can test the thermal fuse continuity. If the above test doesn’t show continuity on the thermal fuse considers replacing the fuse.

4.Faulty thermostat

The thermostat is another key component of the dryer that helps the dryer regulate the temperature.

There are some situations when the temperatures inside the dryer can reach a maximum.

In such a situation, the thermostat instructs the heating element to shut down to prevent dryer from catching fire.

Though, the thermostat doesn’t produce heat but when it fails component that produces heat may not function properly.

Therefore, if your dryer is not heating up and the problem persists check the thermostat.


The thermostat is located around the heating compartment or blower.

A faulty or malfunctioning thermostat must be replaced with a new one. To identify if the thermostat is defective or not I suggest you conduct a continuity test.

If the thermostat fails the continuity test consider replacing the thermostat.
