Understanding the Heating Element in LG Dryers
What is a Heating Element?
The heating element in an LG dryer is a metal coil or ribbon that converts electrical energy into heat through resistive heating. As electricity flows through the element, it heats up, providing the necessary warmth to dry clothes efficiently. The heated air is then circulated inside the drum to evaporate moisture from garments.
Role of the Heating Element in Dryer Operation
The heating element's primary function is to generate heat during the drying cycle. It works in tandem with the dryer’s blower motor, thermostat, and sensors to regulate temperature and airflow. When the dryer starts, the heating element heats up, and the blower circulates warm air through the drum. Once the desired temperature is reached, the thermostat maintains it, and the cycle continues until the clothes are dry.
Types of Heating Elements in LG Dryers
LG manufactures various models of dryers, and their heating elements may differ slightly. The common types include:
- Coil-type heating elements: Wound metal coils made of high-resistance materials like nichrome.
- Ribbon-type heating elements: Flat, ribbon-like elements that provide even heat distribution.
- Integrated heating modules: Some newer models feature integrated heating modules that combine multiple components for ease of replacement.

Signs of a Faulty Heating Element
Common Symptoms Indicating a Problem
Recognizing early signs of a faulty heating element can save you time and money. Common symptoms include:
- Dryer runs but does not produce heat: Clothes come out damp or cold.
- Long drying cycles: The dryer takes longer than usual to dry clothes.
- Error codes: Many LG dryers display error codes such as "HE" or "F2" indicating heating issues.
- Burning smell or visible damage: A burnt smell or visible breakage in the heating element.
- Clothes still damp after cycle completion: The dryer’s heat output is insufficient.
Causes of Heating Element Failure
Understanding why heating elements fail can help prevent future issues:
- Carbon build-up or debris: Accumulation can cause overheating.
- Thermal stress: Repeated heating and cooling can lead to metal fatigue.
- Electrical issues: Power surges or faulty wiring can damage the element.
- Age and wear: Over time, the element naturally deteriorates.
- Physical damage: Impact or mishandling can crack or break the element.

How to Check if the Heating Element is Faulty
Tools Needed
- Multimeter (for continuity testing)
- Screwdriver set
- Gloves and safety goggles
Step-by-Step Testing Procedure
1. Unplug the Dryer: Always disconnect power before beginning any repair.
2. Access the Heating Element: Remove the back panel or front panel as per your model’s manual.
3. Locate the Heating Element: It’s usually a coiled wire housed within the heater assembly.
4. Inspect Visually: Look for signs of damage such as breaks, burns, or corrosion.
5. Test for Continuity:
- Set the multimeter to the continuity setting.
- Remove the heating element’s wires.
- Place the multimeter probes on each terminal of the element.
- A reading of “0” or a very low resistance indicates continuity; no reading indicates a broken element.
6. Check for Shorts: Ensure there are no shorts to the ground.
7. Replace if Necessary: If the element shows no continuity or is visibly damaged, it should be replaced.
