Where is that terrible noise coming from?
A noisy dryer may not just be annoying, it may also indicate a significant problem. While many of the possible causes will require the expertise of a repair technician, troubleshooting the problem will save down time and may prevent even more serious issues from occurring.
Take a look at the 10 most common noisemakers and then contact FIX Appliances CA to answer your questions or to schedule an appointment:
Noise Cause #1 — Drive Belt
A belt is used to rotate the drum on both gas and electric dryers. The long, thin belt wraps completely around the drum, tension pulley and drive motor. With age and use, the drive belt can dry out, become frayed and even separate to cause a thumping noise every time the drum turns.
- You can inspect the drive belt by removing the front panel of the dryer.
- If you notice any signs of wear such as cracking or fraying, contact FIX Appliances CA to replace it.
Noise Cause #2 — Drum Roller
Several rollers at the front and rear of most dryers are used to support the drum. After years of use, these rollers can wear out and cause the drum to stop moving freely. A squealing or thumping noise may indicate one or more drum rollers have worn flat, broken, or may be binding.
Contact a certified technician to inspect the rollers for wear. If one or more are severely worn, the entire set of drum rollers will be replaced to ensure they wear evenly.
Noise Cause #3 — Drum Roller Axle
The shafts that hold the drum rollers at the front and rear of the dryer are called axles. With extended use, both the rollers and axles can wear out and create a loud rumbling noise.
In order to determine if the axles have worn out, the belt must be removed and the drum turned by hand.
A repair technician will inspect the rollers and axles for wobbling and to make sure the drum spins freely. If even one axle is worn, all will be replaced to keep the drum turning smoothly.
Noise Cause #4 — Blower Wheel
Both gas and electric dryers use a blower wheel to draw air through the heating chamber, through the drum, and out the exhaust vent. There are three main issues that can cause a thumping or roaring noise from the blower wheel:
- Lint, small articles of clothing, and other objects can get past the lint filter and lodge in the blower wheel.
The blower wheel came loose from the threaded shaft or the clamp holding it in place came off.
- The plastic blower wheel has worn out.
- Remove the dryer vent to assess the air flow. A weak air flow can indicate an obstruction or wear.
- Contact a repair technician. He will check for objects hitting the wheel, inspect the blower wheel for wobble, and replace it as necessary.
Noise Cause #5 — Drum Bearing
Some dryers use a bearing to support the back of the drum. It can be set up as a ball and socket or shaft with a sleeve bushing. A squeaking or squealing noise may indicate the bearing has worn.
To determine if this is the problem, a technician will need to remove the dryer belt and then turn the drum by hand. If it turns hard or makes grinding sounds, he’ll replace the drum bearing.
Noise Cause #6 — Baffle or Lifter
The baffles or lifters located inside your drum keep clothes from sticking to the inside of the drum and help to tumble and fluff them as they dry. Small objects like loose change can become lodged underneath and cause a rattling noise. Worn or loose baffles can also cause a clumping noise as well as damage your clothing.
- Check for loose change or other objects stuck under the baffles, and remove them.
- Contact a repairman to replace loose or worn baffles or lifters.
Noise Cause #7 — Drum Slide, Glide, or Pad
Made from Teflon, nylon, or plastic, drum slides (glides) provide support for the dryer’s front and sides. They have a felt or cork backing to provide a smooth surface for the drum to rotate on. As they wear out, you’ll notice a scraping sound.
To determine if the slides (glides) are worn out, the dryer’s cabinet must be removed. Contact a service technician to inspect and replace the glides as a set.
Noise Cause #8 — Idler Pulley
The idler puller provides tension to the drum belt to prevent slippage when the dryer has a load in it. Because of its high-speed rotation, increased friction may cause the dryer to squeak or squeal as the idler pulley starts to wear. As it wears further, the noise will sound like a loud scraping or thumping.
A technician will need to remove the belt to check the idler puller operation. Any binding, wear, or wobble will require replacement.
Noise Cause #9 — Idler Assembly (Shaft)
The idler assembly (shaft) may become damaged or worn from a problem with the idler pulley that provides tension on the drum belt. This may cause a loud scraping or thumping noise as it worsens.
The idler assembly is located at the bottom of the dryer near the drive motor. A technician can service the part through the lower access panel or front of the machine. Any wear to the idler assembly should prompt replacement of the unit as well as the drive belt.
Noise Cause #10 — Drive Motor
The drive motor on gas and electric dryers turns the blower and drum. There are a number of noises that may indicate a problem with the drive motor—rattling from a loose pulley, high-pitched noise from bad bearing, or a humming noise from a bad switch on the motor.
Your technician should remove the drum belt or blower wheel to make sure the motor is the problem. Once he’s determined all other parts are working properly, replace the drive motor.
A noisy dryer can be a symptom of a bigger problem. If you’re having trouble determining where the noise is coming from, you can purchase a dryer maintenance kit. It will contain all the common replacement parts needed to eliminate many of the noisy issues.
