Quick answer

If your dryer isn't catching lint, start by cleaning the lint filter and checking for blockages in the vent system. A clogged vent or damaged duct can prevent lint from being captured properly.

Confirm the symptom

Lint builds up inside the dryer drum
Excess lint accumulates on the floor or in the room
Dryer takes longer to dry clothes

Tools and prep

Screwdriver (if needed to access vent)
Vacuum with hose attachment
Lint brush or old toothbrush
Work gloves
Turn off the dryer and unplug it before starting

Step-by-step troubleshooting

Clean the Lint Filter
Do: Remove the lint filter from the dryer and clean it thoroughly with a brush or rinse under water if it's washable.
Observe: Lint is removed from the filter and no buildup remains.
Means: The lint filter was clogged, which can reduce airflow and cause lint to escape.
Next: Check the vent system if lint still escapes after cleaning the filter.
Inspect the Vent Hose
Do: Locate the vent hose behind the dryer and disconnect it from the wall or duct. Inspect for lint buildup or blockages.
Observe: Lint or debris is found inside the vent hose.
Means: A clogged vent hose prevents lint from being expelled properly, causing it to fall back into the dryer.
Next: Clean the vent hose with a vacuum or brush.
Clean the Vent Hose
Do: Use a vacuum with a hose attachment or a vent cleaning brush to remove lint from the inside of the vent hose.
Observe: The vent hose is free of lint and debris.
Means: Clearing the vent hose restores proper airflow and lint removal.
Next: Reconnect the vent hose and test the dryer.
Check the Exterior Vent Cap
Do: Go outside to the dryer vent and inspect the vent cap for lint buildup or a stuck flap.
Observe: The vent cap flap is stuck or clogged with lint.
Means: A blocked vent cap restricts airflow, causing lint to recirculate inside the dryer.
Next: Clean the vent cap and ensure the flap moves freely.
Test Dryer Operation
Do: Plug the dryer back in, run a test cycle, and check if lint is still escaping.
Observe: Lint is caught in the filter and vent system without buildup.
Means: The issue is resolved if lint is properly captured and expelled.
Next: If lint still escapes, inspect the dryer's internal duct for blockages.
Inspect Internal Duct (Advanced)
Do: If lint still escapes, access the internal duct by removing the dryer's back panel (refer to the manual). Check for lint buildup or damage.
Observe: Lint is found inside the internal duct or the duct is damaged.
Means: An internal clog or damaged duct prevents proper lint removal.
Next: Clean the duct or replace it if damaged.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Clogged Lint Filter A dirty lint filter restricts airflow and allows lint to escape into the dryer and room.	Common	Easy	Lint filter (if disposable)
Clogged Vent Hose Lint buildup in the vent hose blocks airflow, causing lint to recirculate inside the dryer.	Common	Easy–Medium	Vent cleaning brush
Blocked Exterior Vent Cap A clogged or stuck vent cap flap prevents lint from being expelled outside.	Sometimes	Easy	None
Damaged Vent Hose A kinked or crushed vent hose restricts airflow and lint removal.	Sometimes	Medium	Replacement vent hose
Internal Duct Clog Lint buildup inside the dryer's internal duct prevents proper lint removal.	Rare	Hard	Vent cleaning brush or professional service
Faulty Dryer Installation Improper installation (e.g., long or improperly connected vent hose) can cause lint to escape.	Rare	Medium	Professional installation service

If you need replacement parts for lint removal issues, consider these options:

Disposable lint filters (if your model uses them)
Vent cleaning brushes for DIY cleaning
Flexible aluminum vent hose for replacement
Dryer vent kit for exterior vent maintenance

Choose a vent hose that matches your dryer's size and connection type. Avoid plastic or foil hoses, which can trap lint.

When to call a professional

Lint buildup persists after cleaning all accessible parts
You suspect an internal duct clog or damage
The vent hose is damaged and difficult to replace
The dryer still doesn't catch lint after all troubleshooting steps
You're unsure about accessing internal components

FAQ

How often should I clean my dryer's lint filter?

Clean the lint filter after every use to maintain optimal airflow and prevent lint buildup.

Can a clogged vent cause a fire hazard?

Yes, a clogged vent increases the risk of dryer fires due to lint accumulation and overheating.

Why does lint still escape after cleaning the filter and vent?

Lint may still escape if the internal duct is clogged or the vent hose is damaged. Inspect these areas next.

Is it safe to use a vacuum to clean the vent hose?

Yes, a vacuum with a hose attachment is safe for cleaning lint from the vent hose. Avoid using high-pressure air, which can push lint further into the duct.
