If you’re a homeowner or tenant who uses a dryer, you may have experienced the frustration of clothes taking too long to dry. Not only is it a time-consuming inconvenience, but it can also lead to higher energy bills and potentially damage your dryer. In this guide, we’ll explore the common causes of slow drying times and provide solutions to help you get your laundry dry in a timely manner.

Causes of a Dryer Taking Too Long to Dry Clothes

Overloaded Dryer

One of the most common culprits for slow drying times is an overloaded dryer. When too many clothes are crammed into the dryer, there simply isn’t enough space for the hot air to circulate properly. This lack of proper airflow can result in damp or even wet clothes, which can be frustrating and time-consuming to deal with.

To prevent this issue, it’s important to make sure you’re not overloading your dryer. Be sure to check the manufacturer’s recommendations for load size and leave some space for the air to circulate.  In addition to prolonging drying times, overloading your dryer can also put a strain on the machine’s components, potentially leading to costly repairs down the line.

Insufficient Power Supply

A dryer requires a considerable amount of power to generate enough heat to dry clothes effectively. If the power supply is inadequate, the dryer won’t be able to generate the necessary heat, leading to prolonged drying times.

To start, check that your dryer is plugged into a dedicated outlet and not sharing a circuit with other high-energy consuming appliances. Sharing a circuit can cause an overload that affects the performance of all devices sharing that circuit. An overloaded circuit may also increase the risk of electrical accidents, such as tripping breakers or electrical fires.

Furthermore, it’s recommended to verify the voltage supplied to your dryer.

Clogged Lint Screen

When the lint screen is clogged, the dryer struggles to push the heated air through the clothes, causing moisture to linger longer. As a result, the clothes take longer to dry, and the dryer may consume more energy to compensate. In some cases, this can even cause the dryer to overheat, leading to potential safety hazards.

To prevent a clogged lint screen, it’s essential to clean it after every use. This promotes adequate airflow through the dryer, allowing it to operate efficiently and reduce the drying time.

It’s also crucial to inspect the lint screen regularly for signs of damage or wear. A damaged or torn lint screen can lead to poor drying results, as it won’t trap the lint and debris effectively. In such cases, it’s best to replace the lint screen promptly to ensure that the dryer operates at maximum efficiency.

Unsealed Drum

To diagnose an unsealed drum, run your hand along the inside of the dryer while it’s running. If you feel air escaping, it’s a sign that the drum seal is damaged or worn, causing air leaks that affect the dryer’s efficiency. It’s essential to address this issue promptly to avoid potential hazards and ensure that your dryer functions correctly.

There can be several reasons why the drum seal is damaged or worn out. One possible cause is regular wear and tear due to frequent use of the dryer. Over time, the drum seal can become brittle and crack, leading to air leaks. Additionally, if the dryer is overloaded or loaded incorrectly, it can put unnecessary pressure on the drum seal, causing it to fail.

Another reason for an unsealed drum is a faulty drum glide or slide. The drum glide or slide is a component that supports the drum and allows it to rotate smoothly. If it’s damaged, the drum can wobble, causing the seal to wear out prematurely and leading to air leaks.

Defective or Broken Blower Wheel

A broken blower wheel can cause longer drying times. It moves hot air through the dryer and out the vent. Common causes of malfunction are wear and tear, overloading, and dust buildup. To diagnose the issue, turn off the dryer, remove the front panel, and look for damage. Check if the blower wheel spins freely. Regular maintenance like cleaning and inspecting the belt can prevent problems and extend the dryer’s life.

Burnt-Out or Dirty Heating Element

The heating element is a crucial component that generates the heat to dry clothes in the dryer. If it’s burnt-out or covered in dirt, it can cause longer drying times, resulting in more energy consumption and higher bills.

To do this, you’ll first need to turn off the dryer and remove the front panel. Check for any visible signs of wear and tear or damage to the heating element. If there is any dirt on the surface of the heating element, clean it using a soft brush, but be gentle to avoid causing any further damage.

However, if the heating element is burnt-out, it’s time to replace it.

Slow drying time

Unsealed Door

A dryer door needs to seal tightly to ensure that hot air is contained inside and not escaping. If hot air is escaping through the door, it means that your dryer isn’t functioning as efficiently as it should be, leading to increased energy bills and longer drying times.

To check if your dryer door is sealed properly, you can run your hand along the inside of the door while it’s running. If you feel hot air escaping, it’s time to replace the door seal. Door seals can become damaged over time due to regular use or because of wear and tear.

Restricted Airflow

Restricted airflow occurs when the dryer vent is clogged with lint or other debris, or if the vent is too long or has too many turns.

To diagnose restricted airflow, you’ll need to inspect the dryer vent for any visible signs of lint or debris. If you notice any buildup, it’s time to clean the dryer vent. You can do this yourself using a vent brush or hire a professional to do it for you. It’s recommended that you clean your dryer vent at least once a year to prevent restricted airflow and maintain your dryer’s efficiency.

Clothes Too Wet After Washing

If your clothes are too wet after washing, it can also lead to longer drying times. This can happen if your washing machine isn’t spinning the clothes properly or if you’re using too much detergent. To prevent this, make sure you’re using the recommended amount of detergent and that your washing machine is functioning properly.

To diagnose why your clothes are too wet after washing, check if the clothes are evenly distributed in the machine and the machine isn’t overloaded. If this doesn’t solve the problem, check the filter and ensure it’s clean. If the issue persists, it may be due to a faulty spin cycle or a broken belt or motor. In this case, it’s best to contact a professional technician for assistance.

Incorrect Residual Moisture Level

Here’s what you need to know to fix this problem:

  • Check your dryer settings: Make sure you’re using the correct settings for the type of clothes you’re drying. Some fabrics require a lower heat setting to prevent damage, while others need a higher heat setting to dry thoroughly.
  • Clean your dryer’s lint filter: A clogged lint filter can cause your dryer to overheat and reduce its efficiency. Make sure to clean the lint filter after every use to prevent this from happening.
  • Inspect your dryer’s vent: Check that the vent leading outside is clear of obstructions and not clogged with lint. A blocked vent can cause hot air to back up into the dryer, reducing its effectiveness.
  • Verify that the moisture sensor is functioning properly: The moisture sensor is responsible for detecting the amount of moisture in the clothes and adjusting the drying time accordingly. If it’s not functioning correctly, it can lead to an incorrect residual moisture level and longer drying times.

Faulty Thermostat

A faulty thermostat may be to blame. Here’s how to diagnose the problem:

  1. Turn off the dryer and unplug it from the power source.
