Understanding the Problem
A noisy dryer is one of the most common and easy-to-detect appliance problems. Sounds like rattling, squealing, thumping, or growling usually point to worn mechanical parts or trapped debris. The noise often appears or gets louder as the drum spins and can vary with load size and drum speed. Typical culprits include worn drum support rollers or bearings, a failing idler pulley or motor, a loose or damaged drive belt, a damaged blower wheel, or worn drum glides. Foreign objects (coins, buttons) or accumulated lint in the blower housing can also create abrupt rattles or whines. Identifying the sound and where it originates will guide you to the correct part to replace.
Common Symptoms
Rattling, squealing/whining, thumping or banging, grinding or growling, increased vibration, intermittent noise that changes with load.
Common Causes
- Worn or seized drum support rollers or rear drum bearing
- Faulty idler pulley or worn drive belt causing squeal/grinding
- Damaged blower wheel, foreign object in blower housing, or worn drum glides

Run the dryer empty and listen closely; place your ear near the front, rear, and blower housing to localize the sound. Manually spin the drum with the door open—if you hear scraping or feel rough spots, check rollers, glides, and bearings first.
Frequently Asked Questions
Can I fix dryer noises myself?
Yes, many dryer noise problems are DIY-friendly if you have basic tools and follow safety steps (unplug the dryer and shut off gas for gas models). Replacing rollers, idler pulleys, belts, blower wheels, or drum glides is common. If the motor or internal bearings are failing, or you're not comfortable disassembling the cabinet, consider a professional.
How much will it cost to repair a noisy dryer?
Parts for common noise fixes are inexpensive: rollers, idler pulleys, glides, and belts typically cost $10–$60. A blower wheel or motor can be $30–$200 or more. Labor from a technician usually adds $100–$300 depending on complexity and region. Always confirm parts for your exact model before purchasing.
