How to Fix / Troubleshooting

Safety first: Turn off and unplug the dryer before accessing the blower or ducts.

Clean lint filter and ducts: Ensure the lint filter is clean and the exhaust hose or condenser is free of obstructions.
Inspect blower wheel: Remove the rear or side panel to access the blower housing. Check for lint clumps, socks, or other objects caught in the fan.
Check fan blades: Inspect the blower wheel for cracks or bent blades that could cause whistling. Replace the blower wheel if damaged.
Verify duct alignment: Ensure internal ducts are properly seated and not partially blocked or crushed.
Reassemble and test: After cleaning and repairs, run a cycle to confirm the noise is resolved.

Dryer emits a high-pitched whine or whistle from the air outlet during operation.
