Common Reasons for LG True Steam Dryer Not Heating 

are you having trouble with your LG dryer not bringing the heat? It’s a real bummer when your trusty appliance leaves you with damp clothes.

The usual suspects? Could be a dodgy heating element, a clogged vent, or even a blown thermal fuse. 

No worries, though. A little appliance repair magic focusing on that electric dryer’s fuse, sensor, or lint buildup might just get those warm, cozy vibes flowing again. 

What Is a LG True Steam Dryer?

An LG TrueSteam dryer is a front-load electric dryer that uses steam to reduce wrinkles and odors in clothes. Main features include:

• 7.4 cubic feet capacity
• 12+ drying cycles
• Steam function
• Stainless steel drum
• Stackable design

This dryer uses real steam to relax wrinkles and remove odors, lessening the need for ironing. It connects to a water fill hose for steam. Typical dimensions are:

• Height: 38 inches
• Width: 27 inches
• Depth: 26 inches

How Does a LG True Steam Dryer Work?

An LG TrueSteam dryer uses steam to reduce wrinkles and odors in your clothes during drying. Here’s how:

• Real steam is generated using a water fill hose and released into the drum.
• The steam relaxes fabric fibers and cleans deeply, removing wrinkles and odors.
• It fluffs up fabric fibers, so you don’t need to iron after drying.
• The SteamSanitary cycle sanitizes items without high heat.

LG TrueSteam dryers usually have a 7.4 cubic feet capacity, with 12+ drying cycles. They feature a NeveRust stainless steel drum and a stackable design to save space.

Common Issues with LG True Steam Dryers

The following table summarizes the exact causes and solutions, extracted from LG’s support page and a repair guide, with additional insights from user discussions. Each entry includes part numbers and URLs for replacement parts where applicable.

Cause	Description	Solution	Relevant Notes
Airflow Blockage	Obstruction in duct work or lint build-up on the air filter restricts heat flow.	Clean inside dryer, behind dryer, and outside exhaust; check for crushed/kinked hoses, holes. Ensure rigid/semi-rigid duct, verify flappers open, remove lint; contact vent specialist if persists.	Common issue; annual vent cleaning recommended for prevention.
Energy Saver Mode	Defaults to air drying without heat for Cotton/Normal cycle, reducing energy use.	Turn off Energy Saver: Press and release for one cycle, or hold for 3 seconds to disable default. Indicator light deactivates; may increase run time but improves heating.	User error; easy fix, but often overlooked.
Sensor Operation Issues	Moisture sensor cuts off at 80% “Normal” dryness, affecting heating for certain loads.	Use Manual/Time Dry for small loads, bed sheets, bulky items, or mixed loads; clean sensors monthly with damp cloth, let dry. Annual vent cleaning advised.	Affects drying efficiency; monthly sensor cleaning crucial for accuracy.
Thermal Fuse Blown	Safety device shuts down power to heating element/ignitor if overheating occurs. Test with multimeter for continuity.	Unplug dryer, remove back covers with ¼” nut driver, test fuse, replace if no continuity. Order part: LG Hi-Limit Thermostat	Common in both gas and electric models; often linked to airflow issues.
Resettable Hi-Limit Thermal Fuse Tripped (Gas only)	Cuts power to ignitor if overheating, often due to clogged vent or lack of service.	Turn power off, remove exhaust, push black button to reset (hear click), reassemble, test.	Gas-specific; reset is simple, but recurring trips suggest vent maintenance.
Ignitor Failed (Gas only)	If ignitor fails, gas doesn’t ignite, no heat produced.	Replace ignitor. Order part: LG Dryer Ignitor	Gas models only; failure often age-related, replace with exact part for compatibility.
Gas Burner Valve Assembly (Gas only)	Gas valve with primary and secondary coils; if one fails (zero resistance), no heat.	Check continuity with multimeter, replace if failed. Order part: LG Gas Burner Valve	Requires multimeter; complex repair, consider professional help if unsure.
Heating Element Burnt Out (Electric only)	Heater coils burnt, prevents drying. Test with multimeter for continuity or inspect for burns.	Unplug dryer, remove back covers with ¼” nut driver, test/replace heating unit. Order part: LG Heater Assembly	Electric models only; visible burns indicate replacement needed, test for continuity first.
Vent Line Clogged	Clogged flexible hose or exhaust prevents proper airflow, can cause overheating.	Unplug dryer, disconnect hose, check for lint buildup, collapse, or blockages, replace hose if needed.	Affects both gas and electric; preventive maintenance (e.g., annual cleaning) is key.
Failed Control Board	Least likely cause, difficult to test, inspect for burnt components.	Unplug dryer, remove top cover, disconnect wires, replace board if needed. Contact manufacturer for part.	Rare, complex; professional diagnosis recommended, as board replacement is costly and technical.

1. Not Heating Up

Heating Element and Thermal Fuse:

Check the heating element for continuity to see if it’s working. Test the thermal fuse, as it can cause no heat if blown.

Thermostats and Sensors:

Test thermostats like the high limit thermostat for continuity to troubleshoot issues with your dryer heating up. Faulty sensors can also prevent heating, so test them too.

Ventilation and Ducts:

Clean dryer vents and ducts regularly to avoid overheating and blowing the thermal fuse.

Start Switch Failure:

Test the start switch for continuity. Replace the switch if it’s not working to start the heating cycle.

2. Not Drying Clothes Completely

Clogged Dryer Vent: A clogged vent can stop airflow, leading to damp clothes. Unplug the dryer, clean the vent pipe, and remove any lint buildup. Check for kinks or restrictions in the exhaust to ensure the LG dryer heating mechanism works efficiently.

Faulty Heating Element: If the heating element is broken, it won’t produce enough heat. Test it with a multimeter and replace if needed, especially if you’re dealing with an LG dryer heating element that’s failed.

Overloading the Dryer: Too many clothes can block airflow. Only fill the dryer half to two-thirds full.

Faulty Thermostat: A bad thermostat can stop the dryer from getting hot enough. Test it with a multimeter and replace if needed.

Sensor Issues: A malfunctioning moisture sensor might cause the dryer to stop too soon. Clean and check the sensor’s position.

3. Making Loud Noises

LG dryers can make sounds like rattling, clicking, pounding, beeping, whirring, or burping when running. These noises might come from hard items like zippers or buttons hitting the drum, the compressor starting up, or the drain pump working during condenser cleaning.

Reducing Noise: To cut noise from hard items, fasten zippers, turn clothes inside out, and empty pockets before drying. Noise from the compressor starts is normal and happens at the start of the drying cycle, but it does not indicate issues with dryer heating. Sounds from the drain pump during cleaning are also normal and not a concern.

Troubleshooting and Fixing Noises: If the dryer makes loud noises like thumping, screeching, or banging, check parts like roller wheels, idler pulley, and blower wheel. Regular maintenance, like inspecting and replacing worn parts, can fix noisy operation in LG dryers.

Possible Causes of LG True Steam Dryer Not Heating

1. Faulty Heating Element

To fix a faulty heating element in an LG dryer, follow these steps:
