- Inspect the Dryer DrumDo: Wipe the interior of the drum with a damp cloth to remove any trapped hair or debris.Observe: Hair or fabric softener buildup is present on the drum walls.Means: Trapped debris is burning during the cycle.Next: Clean the drum thoroughly and run a test cycle.
- Clean the Dryer Vent and Exhaust DuctDo: Disconnect the vent hose from the back of the dryer and use a vacuum to remove lint and debris. Check the exhaust duct outside the house for blockages.Observe: Lint and hair are clogged in the vent or duct.Means: Blocked vent is causing overheating and burning smells.Next: Clean the entire vent system and ensure it is clear.
- Check the Dryer's Exterior Vent CoverDo: Remove the vent cover outside the house and clean it with a brush or vacuum.Observe: Vent cover is clogged with lint and debris.Means: Blocked vent cover is restricting airflow and causing overheating.Next: Clean the vent cover and ensure it is clear.
