Understanding the Problem
The dryer door seal (also called the door gasket or drum seal) is the flexible strip that runs around the opening between the dryer door and cabinet. Its job is to keep hot air and lint inside the drum and to maintain proper airflow. When the seal is worn, torn, compressed, or missing, hot air escapes, drying performance drops, lint can blow into the cabinet, and the dryer may overheat or take much longer to dry clothes. A bad door seal can also allow lint and moisture to collect around the door, cause rattling or scraping noises as items catch on the torn edge, and may create a burning or musty smell if lint accumulates against the heater or motor. Replacing a damaged seal restores drying efficiency, reduces energy use, and lowers the risk of lint-related problems or premature component failure.
Common Symptoms
Longer drying times, warm air escaping around the door, visible gaps or tears in the gasket, lint buildup at the door edge, unusual noises when the drum rotates, or a burning/musty smell.
Common Causes
- Normal wear and tear from repeated opening/closing and drum contact
- Physical damage from items caught between the door and seal or from slamming the door
- Degradation from heat, detergent residues, or chemical exposure
- Improper installation or missing/failed retaining clips allowing the seal to shift
- Door or cabinet misalignment causing uneven compression and premature wear

Helpful Repair Tip
With the dryer off and door open, shine a flashlight along the seal and look for cracks, gaps, missing sections, or flattened areas; try sliding a sheet of paper around the perimeter—if the paper pulls out easily at multiple spots, the seal is not making a tight contact and likely needs replacement.
Frequently Asked Questions
How much does it cost to replace a dryer door seal?
Parts alone typically range from about $15 to $80 depending on brand and whether it's an OEM kit. If you hire a technician, labor adds roughly $80–$200 depending on local rates and difficulty. Many owners can replace the gasket themselves in 30–90 minutes using basic tools—check your model’s service manual or a reputable video for model-specific steps.
Can I keep using the dryer with a damaged door seal?
It's not recommended. A damaged seal reduces drying efficiency, increases energy use, and lets lint enter the cabinet where it can clog vents, accumulate on heating elements, or cause overheating. If the seal is torn enough that clothing can catch on it or lint is building up, replace it as soon as possible to avoid further damage or a fire risk.
