Confirm the symptom
- Loud thumping or squealing during operation
- Noise increases when dryer is loaded
- Unusual rattling or grinding sounds
Tools and prep
- Screwdrivers (flathead and Phillips)
- Flashlight
- Work gloves
- Lint brush or vacuum
- Owner's manual

Step-by-step troubleshooting
- Check Lint Filter and VentsDo: Remove and clean the lint filter. Inspect the vent hose for blockages.Observe: Lint buildup or clogs in the vent.Means: Clogged vents can cause strain and noise.Next: Clean the filter and vent. If noise persists, proceed to next step.
- Inspect Drum Rollers and BearingsDo: Access the drum rollers by removing the front panel or drum. Check for wear or looseness.Observe: Worn, cracked, or loose rollers; grinding noise when spinning.Means: Faulty rollers cause imbalance and noise.Next: Replace damaged rollers or bearings.
- Check Drive BeltDo: Locate the drive belt (usually around the drum). Inspect for cracks or looseness.Observe: Cracked, frayed, or loose belt.Means: A damaged belt can cause squealing or thumping.Next: Replace the belt if damaged.
- Examine Idler PulleyDo: Find the idler pulley (near the belt). Spin it by hand.Observe: Squeaking or rough spinning.Means: A faulty pulley can cause belt noise.Next: Replace the idler pulley.
- Look for Foreign ObjectsDo: Check inside the drum and dryer compartment for loose items.Observe: Foreign objects like coins or small clothing parts.Means: Objects can cause rattling or thumping.Next: Remove any foreign objects.
- Test Motor and Blower WheelDo: Listen for grinding or humming from the motor area. Check the blower wheel for damage.Observe: Unusual motor sounds or damaged blower wheel.Means: Motor or blower issues may require professional repair.Next: If motor or blower is faulty, contact a professional.
