Can I Leave My Dryer On When Not Home? Exploring the Safety and Energy Efficiency Considerations

As a busy homeowner, you may often find yourself wondering if it’s safe and energy-efficient to leave your dryer running when you’re not at home. After all, it’s convenient to start a load of laundry and let the dryer do its job while you attend to other tasks or run errands.

However, it’s crucial to consider the safety and energy efficiency implications of leaving a dryer unattended. In this article, we will explore these considerations and discuss how smart solutions can provide a viable solution to this dilemma.

Safety Concerns

The safety of your home and loved ones should always be a top priority. When it comes to leaving a dryer on when not at home, there are potential hazards to consider. One of the most significant risks is the possibility of a dryer-related fire. Lint buildup in the dryer vent or lint trap can ignite, resulting in a dangerous fire that can quickly spread throughout the home. Electrical malfunctions or overheating of the dryer can also pose a fire hazard. Therefore, it’s crucial to follow the manufacturer’s instructions and maintenance guidelines to minimize these risks.

According to the National Fire Protection Association (NFPA), dryers accounted for an estimated 13,820 home structure fires in the United States in 2019 alone, resulting in 51 civilian deaths, 380 civilian injuries, and $238 million in direct property damage. These statistics highlight the severity of the issue and emphasize the importance of taking necessary precautions when using a dryer.

Energy Efficiency Considerations

Aside from safety concerns, leaving a dryer on when not at home can also impact energy efficiency. Dryers are known to be energy-intensive appliances, consuming electricity or gas to generate heat, tumble clothes, and exhaust moisture. When a dryer runs without anyone around to monitor the drying process , it can result in wasted energy. Extended drying times or running the dryer for longer than necessary can significantly impact your energy consumption and utility bills.

To optimize energy efficiency, it’s essential to use the right drying settings, load size, and duration for your laundry. Overdrying clothes can not only waste energy but also cause wear and tear on your garments. It’s recommended to use dryer sensors or select shorter drying cycles to avoid unnecessary energy usage.

Smart Solutions

With the advent of smart home technology, there are now solutions available that can help address the issue of leaving a dryer on when not at home. Many modern dryers come equipped with smart features such as built-in sensors and connectivity options that can enhance safety and energy efficiency.

Our Recommendation:

For example, some smart dryers have moisture sensors that can detect when the clothes are dry and automatically shut off the dryer, preventing over-drying and saving energy. Additionally, some smart dryers can send notifications to your smartphone when the drying cycle is complete, allowing you to promptly remove the clothes and avoid leaving the dryer running longer than necessary.


Is it safe to leave my dryer on when I’m not at home?

It is generally not recommended to leave your dryer on when you are not at home due to the risk of dryer-related fires.

Why is it dangerous to leave my dryer on when I’m not home?

Dryers generate heat, and if left on for extended periods without supervision, they can potentially cause a fire if lint accumulates or if there is a malfunction in the dryer’s components.

Are there any additional safety tips to keep in mind when using my dryer?

Yes, it’s important to never overload your dryer, avoid drying items that are soiled with flammable substances, and always make sure your dryer is properly installed and vented to the outside to prevent accumulation of lint and reduce the risk of fires.


In conclusion, while it may be tempting to leave your dryer on when not at home for the sake of convenience, it’s important to prioritize safety and energy efficiency. The risks of dryer-related fires and wasted energy consumption should not be taken lightly. However, with the emergence of smart home technology, there are now viable solutions available to address this dilemma.

Investing in a smart dryer with built-in sensors and connectivity features, or using other smart home devices to remotely control or monitor your dryer, can provide added safety and energy efficiency benefits. It’s crucial to always follow the manufacturer’s instructions and maintenance guidelines, and consider implementing smart solutions to optimize the operation of your dryer when you’re not at home.
