Every homeowner relies on their appliances to work efficiently and effectively. A dryer plays a pivotal role in helping you manage your laundry among the household appliances. So, when your Whirlpool dryer starts making a loud rumbling noise, it can be both an annoyance and a cause for concern. Addressing this noise swiftly can prevent more significant malfunctions and ensure the longevity of your appliance.

Whirlpool Dryer Making Loud Rumbling Noise

When your Whirlpool dryer starts producing a distinctive rumbling sound, there are a few key culprits to consider. Let’s dive into the most common reasons:

Blower Wheel Issues

The blower wheel channels hot air into the dryer drum and expels moist air from the dryer vent. Over time, lint or small clothing articles can clog this wheel. When this happens, the blower wheel can’t rotate freely, causing it to produce a rumbling noise. Also, the wear and tear of the wheel can result in it becoming loose from the motor shaft, adding to the noise levels.

Worn Drum Support Rollers

The drum support rollers support the dryer drum and allow it to rotate smoothly. With regular usage, these rollers can wear out or become misshapen. When this happens, they cause a continuous rumbling or thumping sound instead of providing smooth rotation during the dryer’s operation.

Faulty Drive Motor

The drive motor is the heart of your Whirlpool dryer. It powers both the drum and the blower wheel. If its bearings wear out, they can produce a loud rumbling or even a high-pitched squeal. Ensuring this motor remains in peak condition is essential for a noise-free drying cycle.

Other Common Noisy Culprits

Damaged Drive Belt

The drive belt is a critical component, looping around the dryer drum and the motor pulley, ensuring the drum rotates. Over time, with constant use, this belt can fray, get damaged, or even snap. When this occurs, you might hear a thumping or squeaking noise emanating from your dryer.

Worn Out Drum Glides or Slides

Positioned at the front of the dryer drum, drum glides or slides help the drum rotate smoothly. They undergo wear and tear, and when they’re worn out, they could lead to a metal-on-metal scraping noise, indicating it’s time for a replacement.

Loose or Damaged Internal Screws and Hardware

Over time, the dryer’s internal screws, brackets, or hardware can become loose due to the machine’s vibrations. This can lead to rattling or knocking noises during operation. Regular checks can help identify and tighten any loose components, reducing the noise.

Diagnosing the Issue

If your Whirlpool dryer is noisy, the first step is to pinpoint the noise source. Always remember to unplug the dryer before you start investigating. Consult the user manual, which often contains troubleshooting guides. If you need clarification or the problem seems complex, feel free to seek appliance repair professional help.

Preventative Maintenance Tips

  • Regular Cleaning: Ensure you regularly clean the lint filter and check the dryer’s internal components for any blockages.
  • Proper Load Sizes: Avoid overloading your dryer. Not only can it cause strain on the machine, but it can also reduce its efficiency.
  • Mind Heavy Items: Overloading with heavy items can stress the drum and its supporting mechanisms. Distribute heavy garments evenly or dry them separately.


A noisy Whirlpool dryer might tell you it needs a little attention. You can avoid more significant, costly issues by promptly addressing the rumbling and other noises. Prioritize maintenance, be attentive to any changes in your appliance’s performance, and you’ll ensure its efficient operation for years to come.
