A dryer without heat can seem like a dealbreaker for both your laundry and your machine. However, sometimes there’s a simple way to solve the problem. Why is my LG dryer not heating up? The vent may be clogged, requiring a cleaning so air can circulate. Learn the DIY solutions and part replacements that can restore function when your dryer won’t heat.

No Heat? No Problem. How to Fix an LG Dryer Not Heating

From a clogged vent to a blown thermal fuse, an LG dryer not heating up can often be fixed with a straightforward solution. The following DIY fixes and part replacements not only apply to LG models but can resolve heating issues for nearly all dryers.

DIY Solutions: Regular Maintenance and Proper Use and Care

Without regular cleanings and the right loading techniques, your dryer may not provide adequate heat to dry clothes. The following reasons for an LG dryer not drying have a simple DIY fix with the right maintenance and use and care.

Clogged Dryer Vent

Over time, lint can accumulate in a dryer vent, creating obstructions that restrict air circulation. This restricted airflow means the moist, humid air inside the dryer cannot escape, leaving clothes damp. LG dryers have a FlowSense Indicator on the control panel that illuminates when the vent is clogged. If there are 2-4 bars illuminated on the Indicator, the vent may be obstructed and requires cleaning. Cleaning the vent every 6-12 months as part of regular maintenance can prevent clogs and blockages.

Follow these steps to perform a dryer vent cleaning for an LG dryer not heating up:

• Clean the lint trap: Remove the trap and scrub it with a soft brush, dish detergent, and warm water. Allow to air dry before replacing.

• Clean the lint trap housing: Use an appliance brush or your vacuum’s narrow hose attachment to remove lint buildup from the filter’s housing.
• Clean the dryer vent: Unplug the dryer and position it away from the wall to disconnect the vent. Circulate the appliance brush or vacuum hose attachment inside the vent to remove lint and debris. Repeat for the vent leading to the exhaust opening on the outside of your home. Reconnect the vent, plug the dryer back in and reposition it in place.

Overloading

Wondering why are my clothes still damp after drying? The dryer may be overloaded. Too much clothing also restricts airflow, leaving little space for heated air to circulate and dry clothes. You may also notice your dryer isn’t spinning as quickly with this heavy load, further limiting circulation.

Avoid overloading with these tips for proper use and care:

• Only fill the dryer with one wash load at a time.
• For optimum circulation, make sure each load only fills ¾ of the dryer drum.
• Provide adequate space for larger items, like bedding, by drying them alone or with just 1 or 2 other pieces.

Part Malfunctions That Require Replacement

In other instances, a part malfunction is responsible for an LG dryer not drying completely. Professional replacement of the following parts can restore heat and function.

Blown Thermal Fuse

A thermal fuse is a safety feature that blows if the dryer is in danger of overheating. When the fuse blows, all dryer function stops and won’t resume until it’s replaced. While a fuse can blow if it’s defective, it often does so if a clogged dryer vent causes overheating. It’s recommended that you check your vents for blockages when the fuse blows. If the vents are clear and multimeter testing confirms the fuse has no continuity, it still requires replacement.

Defective Heating Element

In electric dryers, the heating element heats the air inside the dryer drum. When you find your LG dryer not heating up, this element may have worn out and can no longer create heat. If multimeter testing of the heating element shows a lack of continuity, it must be replaced.
