Why is my dryer making a loud screeching noise?
A loud screeching noise in your dryer is typically caused by worn-out drum bearings, a frayed drive belt, or failed idler pulleys that create high-pitched friction during rotation. You should stop using the appliance immediately to prevent motor damage or a potential fire hazard until the faulty component is replaced.
When your dryer starts making a loud, unusual noise, it can be more than just an annoyance. Our technicians have 15+ years of combined industry experience serving Melbourne households and have practical experience diagnosing common dryer faults, including unusual or screeching noises. Worn components, restricted airflow, or other mechanical issues can contribute to these sounds, so having the appliance inspected can help identify the cause before the problem becomes more serious.
Common Culprits Behind the Screech
Most modern dryers rely on a system of pulleys and rollers. When these lose their lubrication or structural integrity, the resulting friction creates that piercing sound.
- The Idler Pulley: This part maintains tension on the drive belt. If the wheel gets stuck, the belt rubs against it, creating a high-pitched squeal.
- Drum Support Rollers: These small wheels hold the drum in place. Over time, the axles wear down, leading to a rhythmic thumping or screeching.
- Rear Drum Bearing: If the bearing at the back of the drum fails, you will hear a constant grinding or squealing sound that gets louder as the load gets heavier.
Drive Belt: If the belt is frayed or slipping, it can “chirp” or screech as it struggles to grip the motor pulley.

How to Diagnose the Noise at Home
Before you call the team at Appliance Repairs Online, you can perform a quick “Spin Test” to narrow down the source of the noise.
- Manual Rotation: With the power off, reach inside and turn the drum by hand. If it squeaks while turning slowly, the issue is likely the drum rollers or the rear bearing.
- The “Thump” Test: If the noise only happens when the dryer is full of wet clothes, the support rollers are the primary suspects as they are under the most pressure.
- Front vs Back: Listen closely to the dryer door. If the sound is louder at the front, it is usually a felt seal or a pulley. If it is coming from the back, it is almost certainly the drum bearing.
If you are located near the CBD or eastern suburbs like Camberwell, we can often get a technician to your door within hours to verify these findings and provide a fix.
Why Local Expertise Matters in Melbourne
Melbourne’s weather plays a surprising role in appliance longevity. During our damp winters, laundry loads get heavier and dryers run longer because line-drying is not an option. This increased “duty cycle” puts immense strain on the mechanical components.
We have seen countless units in the Dandenong Ranges area suffer from seized bearings due to the higher moisture levels. At Appliance Repairs Online, we carry parts specifically suited for the brands most common in Victorian homes, ensuring your repair lasts through the next cold snap.
Step-by-Step Guide to Preventing Dryer Squeaks
- Do Not Overload: Placing too many heavy towels in the drum at once wears out the rollers prematurely.
- Level the Appliance: Ensure your dryer is sitting flat on the laundry floor. Use a spirit level; if it is tilted, the drum will rub against the housing.
- Regular Cleaning: Lint buildup can find its way into the pulleys and bearings, acting like sandpaper on moving parts.
Professional Inspection: A biennial service can catch a “chirp” before it becomes a “screech.”
