4 Troubleshooting Tips for a LG Dryer Not Heating

Without constant cleanings and proper loading techniques, the LG appliance will not dry your clothes normally and 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. Clogged Dryer Vent

Lint may collect in a device over time, clogging it and limiting airflow. Because of the blocked airflow, moist, humid air will remain in the dryer, 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.
• Take the vacuum cleaner's narrow hose to clear the lint from the filter’s 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

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 slower, minimizing circulation even more.

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 only fills ¾ of the dryer drum for 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 the professional to examine the reason or to replace certain elements.

3. Blown Thermal Fuse

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. Experts recommend testing the vent for blockages using a multimeter if the fuse blows. If it is clear, the fuse needs to be changed.

4. Burn 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.
