Electric clothes dryers are supposed to quietly churn out warm, fluffy clothes. However, a recent study found that almost 60% of all clothes dryers made some sort of noise when in use. There are several reasons why your dryer might be running louder than normal, such as a faulty switch, a blocked fan, or a worn-out drum bearing. If you hear a rattling noise, it might be because of small hardware or items like zippers, buckles, buttons, or loose coins inside the drum. A loud rumbling noise could be due to a loose, off-balance, or lint-obstructed blower wheel. If you hear a grinding or squeaking noise, it could be because your rollers or bearings are starting to wear out. In some cases, loud noises could be due to wiring problems or improper voltage.

Rattling noises
Electric clothes dryers typically make a gentle whirring sound as they quietly churn out warm, fluffy clothes. However, if your dryer starts to make loud or unusual noises, this could indicate a problem.
Secondly, rattling could be due to loose parts inside the machine, such as a screw, nut, or bolt that has come loose. In some cases, the belt that turns the drum may have been installed too loose, causing it to slip and create a rattling sound as it heats up. Additionally, if the motor pulley is loose, it can also result in rattling.
If you cannot identify or resolve the source of the rattling noise, it is recommended to contact a professional appliance repair service for assistance. They can help diagnose and fix the issue to ensure your dryer operates safely and effectively.

Blocked fan
If your electric clothes dryer is making loud noises, there are several potential causes. Firstly, it is important to determine the type of noise the dryer is making. A rattling noise could be caused by loose items inside the drum, such as coins, zippers, or other small objects. It could also be due to loose parts, such as screws, nuts, or bolts that have come loose inside the machine. A thumping noise is usually nothing to worry about and could be caused by an unbalanced load or worn-out rollers.
If you hear a grinding or squeaking noise, it could indicate that the rollers or bearings are starting to wear out. The bearings help support the rollers, and if they become worn, they can cause noise. The blower wheel, which circulates air within the drum and expels it through the rear vent, may also be the culprit. If it becomes loose, off-balance, or obstructed by lint or debris, it can cause a loud rumbling noise.
Additionally, the drive belt that helps rotate the drum may be the issue. Over time, the belt can become worn and may need to be replaced. A worn-out belt can cause a thumping or squealing noise. If the noise is a humming sound, it could be a sign that the motor is starting to fail.
To troubleshoot a noisy dryer, you can try the following:
- Check for any loose items inside the drum and remove them.
- Inspect the blower wheel for any obstructions or damage.
- Ensure that the dryer is level and has not been moved recently, as this can cause components to rub against each other.
- Consult the user manual or online guides for your specific model to determine the expected decibel level (dBA). Compare this to the measured decibel level of your dryer using a sound meter application on your smartphone.
- If the noise persists or you are unsure, it is recommended to contact a professional technician for further assistance.

Worn-out drum bearing
Electric clothes dryers are supposed to quietly churn out warm, fluffy clothes. So, if your dryer starts making loud or unusual noises, it is likely that something is wrong. A worn-out drum bearing is one of the most common causes of a loud electric clothes dryer.
The drum bearings support the weight of the dryer drum and allow it to rotate smoothly as it dries your clothes. They help to reduce the friction created when the drum is spinning, keeping the drum stable and reducing noise. There are both front and rear drum bearings, and they are crucial for maintaining the stability and balance of the dryer drum. They ensure that the clothes dryer drum rotates evenly, preventing excessive wobbling or vibrations that could lead to noise, wear on other components, and potentially uneven drying of the clothes.
Over time, the drum bearings can wear out due to friction, causing the drum to become misaligned or unstable. If the drum bearings are damaged, you will notice that the drum is unstable and is accompanied by an unusual noise, such as a squealing or grinding noise. This is because, as the bearings wear out, the friction in the dryer increases, leading to a louder noise.
If you suspect that the drum bearings are causing your dryer to make loud noises, you can check for signs of wear and tear by turning the drum by hand. If it feels loose or wobbles, the bearings may be damaged. To fix this issue, you will need to replace the drum bearings. It is important to follow the manufacturer's guidelines and use a lubricant specifically designed for this purpose, such as dryer bearing grease.
- Unplug the dryer and disconnect the power supply to prevent the risk of electric shock.
- Remove the top panel, front panel, or rear access panel to gain access to the drum.
- Inspect the drum bearing for any signs of wear and tear.
- If the bearing is damaged, remove it by disengaging the tabs, clips, or screws holding it in place.
- Install the new drum bearing, ensuring it is securely fastened and aligned according to the manufacturer's specifications.
- Reinstall the drum and any removed panels, and plug the dryer back into the power outlet.

Loose parts
If your electric clothes dryer is making loud noises, it could be due to loose parts. Here are some common issues with loose parts that can cause loud noises in your dryer:
Baffles or Lifters
Baffles or lifters are parts inside the dryer that tumble and fluff clothes, preventing them from sticking to the inside of the drum. Over time, these parts can become loose or worn out, causing a rattling noise. If you suspect this is the issue, it is recommended to contact an appliance professional to replace the worn or loose baffles or lifters.
Drive Motor
The drive motor is responsible for rotating the motor shaft, which in turn rotates the idler pulley and the drive belt, ultimately rotating the dryer drum. If the motor pulley is loose, it can cause a rattling noise. Additionally, if the bearings in the drive motor need to be replaced, you may hear a squealing noise. In such cases, it is advised to seek professional assistance.
Blower Wheel
The blower wheel circulates air within the dryer drum and expels it through the rear vent. If the blower wheel becomes loose, off-balance, or obstructed by lint or debris, it can produce a loud rumbling noise. When functioning correctly, the blower wheel turns both the motor and the drum. If the rumbling noise persists or the components fail to spin together, professional help may be required.
Drum Belt
The drum belt helps rotate the dryer drum, allowing your clothes to dry. Over time, the belt can become worn and may need to be replaced. A worn-out drum belt can cause squealing or thumping noises. If you suspect an issue with the drum belt, it is recommended to consult a professional for assistance.
Rollers
Rollers are located under the dryer drum and aid in its rotation. If the rollers become worn out, they can start to make noises such as thumping or squeaking. Worn-out rollers may require replacement by a professional to ensure the proper functioning of the dryer.
It is important to address loud noises in your electric clothes dryer as they may indicate issues with loose parts that require maintenance or repair. If you are unsure about the source of the noise or how to fix it, it is always best to consult a qualified appliance technician.

Wiring issues
If your electric clothes dryer is not working, there could be a wiring issue. Firstly, check that the dryer is plugged in. The plug may have become dislodged, which is a simple fix. If it is plugged in, the next step is to check the electrical panel to see if the fuse or circuit breaker is blown or tripped. If the circuit breaker has been tripped, this could be due to a wiring problem in the machine, an issue with the dryer outlet or cord, or a problem with the wiring coming from the electrical panel to the dryer. Poor electrical connections at the connection point of the cord and outlet and at the electrical terminals can increase the risk of an electrical fire, so it is important to get this checked by a professional.
If the circuit breaker is not tripped, the next step is to check the power cord for any damage or signs of wear that could prevent the dryer from receiving power. If the cord looks intact, the terminal block may be loose, which can also prevent the dryer from receiving power. If you are uncomfortable working with electricity, it is recommended that you call an electrician to inspect your dryer. They will inspect the dryer circuit and wiring configuration and check for any signs of arcing or black soot.
If you are installing a new electric dryer, it is important to ensure that your laundry room is equipped with a 240-volt outlet to power the unit safely. The black and red wires should be connected to the black and red posts on the back of the dryer, and the white wire should be connected to the neutral post. The integrity of the dryer circuit cable and wiring should be checked by a professional to ensure it is adequate.
