♨️ Dryer making squealing or banging noise

⚠️ Common Causes

Drive belt worn, blower wheel cracked, idler pulley bearing worn, drum roller bearings failed, foreign object in drum

🔧 Parts to Check

• Drive belt
• Blower wheel
• Idler pulley
• Drum rollers

🔧 Troubleshooting Steps

1. Check for foreign objects in drum — coins, keys, buttons can cause loud banging
   ✓ Expected: No objects found
2. Check drive belt — remove and inspect. Worn or glazed belt = squealing noise
   ✓ Expected: Belt in good condition
3. Check idler pulley — should spin freely. If grinding or squealing, replace bearing
   ✓ Expected: Spins freely, no noise
4. Check drum rollers — spin rollers by hand. If grinding or rough, replace all 2-4 rollers
   ✓ Expected: Rollers spin smoothly
5. Check blower wheel — if cracked, blade hits housing and causes loud noise. Inspect through exhaust opening
   ✓ Expected: Blower wheel intact
