LG Dryer Overheating? Check for These Problems If Your Dryer Is Too Hot

If you’ve noticed your LG dryer overheating, it’s essential to address this problem promptly. Overheating can not only damage your clothes but also pose a safety risk. In this detailed guide, we’ll explore various reasons why your LG dryer might be running hotter than usual and offer practical solutions to these common issues.

Understanding the Causes of an LG Dryer Overheating

Overheating in LG dryers can stem from several sources, ranging from user errors to mechanical faults. Identifying the root cause is the first step to ensuring your dryer functions safely and efficiently.

Common User Errors

Interrupting the Dryer Cycle

LG dryers are designed with a specific cycle structure, including a Cool Down phase towards the end of the cycle. This phase allows the clothes to gradually cool down after the intense heating process.

If you frequently open your dryer before the cycle is complete, you might be interrupting this important stage, leading to clothes that are unexpectedly hot to the touch. It’s advisable to allow the cycle to finish completely before removing your laundry.


An overloaded dryer is one of the most common causes of overheating. When too many clothes are crammed into the dryer, it restricts the flow of air, which is essential for effectively removing moisture and maintaining a consistent temperature.

This can cause the dryer to work harder and heat up beyond its designed limits. To avoid this, make sure to dry smaller batches of laundry and not exceed the manufacturer’s recommended load size.

Dryer Settings Issue

Different fabrics and load sizes require different heat settings. For instance, heavy materials like towels need more heat than delicate items. Using the incorrect setting can lead to excessive heat for a given load, causing the LG dryer to overheat. Always refer to your LG dryer’s manual to select the appropriate settings for your laundry.

Maintenance Issues

Exhaust Vent Is Clogged

A clogged exhaust vent is a significant and common culprit behind an overheating dryer and other dryer heating issues. Over time, lint and debris can accumulate in the vent, obstructing the flow of hot air out of the dryer.

This not only causes overheating but also poses a fire hazard. Regularly inspect and clean the exhaust vent to ensure it’s clear of lint and obstructions.

Lint Screen Needs Cleaning

The lint screen plays a crucial role in maintaining airflow within the dryer. A clogged lint screen can drastically reduce this airflow, causing the dryer to retain more heat than usual. Cleaning the lint screen after every cycle is an easy yet effective practice to prevent your dryer from overheating.

Mechanical or Functional Problems

Thermostat Malfunction

The thermostat in your LG dryer regulates the internal temperature. A malfunctioning thermostat may fail to turn off the heating element at the appropriate time, leading to excessive heat build-up. If you suspect a thermostat issue, it might require professional assessment and replacement.

Faulty Heating Element

The heating element can become defective over time, leading to unregulated heat production. If the element doesn’t cycle off when it should, it can cause the dryer to generate more heat than necessary, leading to overheating. This is a complex issue that often needs professional intervention.

Drum Seal Worn Out

The drum seals ensure that hot air remains within the drum and does not leak into other parts of the dryer. If these seals are worn out or damaged, excess hot air can escape into parts of the machine not designed to handle high temperatures, contributing to overheating. Replacing worn drum seals can often resolve this issue.

Defective Dryer Timer

The dryer timer controls the duration of each drying cycle. A malfunctioning timer can lead to extended cycles, causing the dryer to run longer than necessary and overheat. If you notice that your dryer’s timer is not advancing as it should, it may need to be repaired or replaced.

External Factors

Low-Quality Venting Materials

The material of your dryer’s venting system plays a vital role in heat management. Using substandard or unsuitable materials, like thin vinyl, can lead to poor heat dispersion and overheating. It’s best to use robust, smooth metal ducting designed specifically for dryer venting.

Exhaust Hose Is Kinked

A kinked or crushed exhaust hose can severely restrict airflow out of the dryer, leading to overheating. Regularly check the positioning of your dryer and the condition of the vent hose to ensure it’s not bent or obstructed.

Other Issues

The location of your dryer can also impact its heating. Placing it in a confined space with poor ventilation can increase the ambient temperature around the machine, leading to your LG dryer getting too hot. Ensure your dryer is in a well-ventilated area to allow for adequate heat dissipation.
