4 Troubleshooting Tips for an LG Dryer Not Heating

Without regular cleanings and proper loading techniques, the LG appliance will not dry your clothes properly and will display an error.

The issues described below for the LG dryer not getting hot have easy DIY solutions to achieve proper use and care of the appliance.

1. Blocked or Clogged Dryer Vent

Lint may collect in a device over time, clogging it and limiting airflow. Because of the blocked airflow, the dryer will retain moist air, leaving clothes soggy.

When lint or debris clogs the vent, it obstructs airflow to your dryer, prolonging the drying process for your clothes. Clearing the vent reduces drying time, enhances your dryer's energy efficiency, preserves your garments, and minimizes the time spent waiting for laundry to dry.

Some LG dryer models include a FlowSense indicator on the control panel that lights up when the vent is dirty. When the indicator shows 2-4 bars, it means that the vent is clogged, and you need to clean it.

Follow these steps for an LG dryer heating element to operate properly:

• Clean the lint trap using a soft brush, dish detergent, and warm water.
• Use the vacuum cleaner's narrow hose to clear lint from the filter housing.
• Remove lint and debris from the vent.
• Attach the vent back in place.

Remember to clean this element every 6-10 months.

2. Overloading the Dryer

Too many clothes additionally block ventilation, leaving minimal space for hot air to circulate and dry the items. With this heavy load, you may also find that your dryer spins more slowly, further minimizing circulation.

To avoid overload, follow these suggestions for correct usage and care:

• Fill the appliance with one wash load at a time.
• Check that the load fills only ¾ of the dryer drum to ensure proper circulation.
• Use only a small number of large items (1 or 2) at once to provide adequate space.

Sometimes, the LG dryer fails to dry entirely due to other issues. Call a professional to examine the cause or replace certain elements.

3. Thermal Fuse Failure

A thermal fuse is a protective element that prevents the appliance from overheating. Once the fuse blows, the dryer stops operating and will not continue until it is replaced. If the fuse blows, experts recommend testing the vent for blockages with a multimeter. If it is clear, the fuse needs to be changed.

4. Burned-Out Heating Element

The LG dryer heating element heats the air inside the drum. When the LG electric dryer doesn’t heat up, the element is probably worn out and can no longer produce heat. Test the component with a multimeter. If the lack of continuity is identified, you must replace it.

LG Dryer Repair Under Warranty

Proper maintenance is essential for keeping any appliance running efficiently, and your LG dryer is no exception. If your LG dryer is stuck in cooling mode, try a quick reset by pressing and holding the “Reset” button for 5 seconds, then turn the dryer back on.

If the dryer continues to blow cold air or fails to heat, consult the manufacturer’s instructions or contact a certified technician to diagnose the issue. Many common problems—such as faulty sensors, heating elements, or control board issues—may be covered under the LG manufacturer’s warranty, making repairs easier and more affordable.
