Many homeowners are wondering whether a dryer can overheat and, if so, what to do when the appliance gets too hot.

You must take immediate action if your dryer is overheating and shutting off. Prior to beginning any action, let the dryer cool down entirely. Check the vent and lint trap afterward for any possible obstructions. Make sure the dryer has enough airflow, and make sure there are no twists or obstructions in the exhaust tube. It is essential to get assistance from a professional technician for additional diagnostic and repair if the issue continues after making these efforts.

In this post, we will look at the main reasons for the dryer getting too hot and examine ways to ensure it won’t happen. After reading through and following, you will be able to take the best care of your dryer. Keep in mind that you don’t need a replacement if your dryer is overheating — most issues can be fixed in minutes. 

Why Does a Dryer Overheat?

Why is a dryer overheating badly? When a dryer gets too hot, it can burn your hands, damage your laundry, or cause a fire. It can also damage the inner workings of the dryer, causing short circuits or burns inside the control system. What causes a dryer to overheat? Here’s the rundown of the most common problems resulting from dryer overheating.

Reason #1. Dust and dirt getting into the air hole

If the air filter inside the dryer is dusty or dirty, it’s harder for the appliance to heat the air. As a result, the device uses more energy to create enough heat. After a short while of use, a dryer with a clogged filter will start overheating and shut off on its own. To make sure you are taking good care of the dryer, clean the appliance after every two or three uses.

Reason #2. Airflow restrictions

If the air gets stuck inside a dryer’s internal duct instead of coming out, you will likely get the dryer overheated. It’s worth checking the power of the airflow from the duct inside the dryer to ensure it’s not clogged or rusty. Since using an old air duct increases the risk of fire hazards, replace it to prolong the device’s lifespan and stay safe.

Reason #3. Heating element issues

When an appliance is brand new, the heating element typically responds effectively to changes in temperature, adjusting the warm air output accordingly when you switch temperature modes. However, as the appliance ages, the heating element may shift and develop minor burns or circuit malfunctions. This can lead to inconsistent heating, causing the dryer to either heat too slowly or too quickly. Over time, a common issue arises where the heating elements in the dryer shift position and come into direct contact with other parts of the appliance, resulting in overheating. It’s advisable to contact a technician to readjust the positioning of the component. If the heating element is irreparably damaged, it may need to be replaced.

Reason #4. The cycling thermostat doesn’t activate

A cycling thermostat serves as a safety measure to prevent the appliance from overheating. When a dryer reaches excessive temperatures, this component reacts by automatically shutting off the appliance. However, if the cycling thermostat fails to function properly, it could be the reason why a dryer is overheating and shutting off unexpectedly. To access, repair, or replace the thermostat, you’ll need to remove the back panel of the dryer. Once you have clear access to the component, conduct some tests using a multi-probe device. If the reading shows ‘zero’, the thermostat is functional. However, if it shows ‘infinity’, it indicates the need for replacement. Fortunately, thermostats are relatively inexpensive, making it a more affordable option than replacing the entire dryer.


How to Prevent a Dryer from Overheating

The best way to prolong the appliance’s lifespan, ensure safe use, and avoid calling a technician is by following good maintenance practices. Here are some tips you can use for troubleshooting when your dryer gets too hot and shuts off.

Tip #1. Control dryer settings

The rule of thumb is that the dryer temperature selector shouldn’t go above “medium.” Using high-mode heating increases the heat damage to your clothes and may cause circuit burns and other mechanical issues. If you don’t have many heating options, choose the temperature setting that doesn’t feel too hot when you put the palm of your hand next to the stream of air from the dryer.

Tip #2. Clean the drum of the dryer thoroughly

Depending on the frequency of use, you should clean your appliance every couple of uses. Otherwise, you will see the dryer overheating and shutting off. Make sure the device is unplugged before you start cleaning. Instead, don’t use anything wet; instead, choose dry cotton pads, a clean makeup sponge, or a sock. To clean the device’s exterior, mix equal parts vinegar and warm water.

Tip #3. Don’t overuse the dryer

Try not to use the dryer for more than 40-50 minutes at one time. Although the overall lifespan of some models can go up to 1,500, don’t let the number trick you. It’s easy to overheat the coil and damage the inner circuits of the system if you keep the dryer on for an extended period. Don’t use a dryer as a household heater, either. Since it was not designed for the purpose, you could increase the risks of fire hazards. Keep a timer nearby to track how long the appliance is running.

Tip #4. Clean the lint screens

Lint screens are one of the dryer components ensuring the safety of usage. For one, they capture lint, grease, and dust, ensuring nothing gets stuck inside the heating coil. Once a screen has stopped letting air through, an appliance can overheat. By keeping these screens clear, you improve the appliance’s energy efficiency, protect your clothes from heat damage, and minimize fire risks. To clean the dryer lint protection screens, remove the protective cover with a snapping or twisting motion. If the protection screen is hardened by dust and dirt, moisten the Q-tip or a sponge, making sure no water is dripping from it. Rotate the Q-tip or sponge across each screen area to remove the dust and dirt.

Tip #5. Make sure the dryer cord doesn’t knot

One reason dryers overheat is that the cord that connects the appliance to the outlet has become knotted. Take some time to untie the knots until the cord makes a perfectly straight line. Plug the dryer back in and evaluate its performance.
