Dryer Takes Too Long to Dry Clothes

Quick answer

If your dryer takes too long to dry clothes, first check the lint filter and vent system for blockages. Ensure the dryer is level and the drum is rotating freely. If these don’t resolve the issue, inspect the heating element or thermal fuse.

Confirm the symptom

• Clothes are still damp after a full drying cycle
• Drying time is significantly longer than usual
• Excess moisture or dampness in the laundry room

Tools and prep

• Screwdrivers (flathead and Phillips)
• Vacuum cleaner with brush attachment
• Lint brush or comb
• Multimeter (for electrical testing)
• Work gloves
• Turn off the dryer and unplug it from the power source
• Ensure the area is well-ventilated

Step-by-step troubleshooting

1. Check and Clean the Lint Filter
   Do: Remove the lint filter and clean it thoroughly with a brush or vacuum.
   Observe: The lint filter is clogged with lint and debris.
   Means: A clogged lint filter restricts airflow, causing longer drying times.
   Next: Clean the lint filter and reinsert it.
2. Inspect the Dryer Vent System
   Do: Check the vent duct for lint buildup and use a vacuum to remove any blockages.
   Observe: Lint or debris is obstructing the vent duct.
   Means: A blocked vent reduces airflow, increasing drying time and posing a fire hazard.
   Next: Clear the vent duct and ensure it is properly connected.
3. Clean the Dryer Drum
   Do: Wipe the interior of the drum with a damp cloth to remove any lint or residue.
   Observe: Lint or residue is present on the drum walls.
   Means: Accumulated lint can trap moisture and hinder the drying process.
   Next: Dry the drum thoroughly before using the dryer again.
4. Check the Dryer Level
   Do: Use a level to ensure the dryer is sitting evenly on the floor.
   Observe: The dryer is tilted or uneven.
   Means: An unlevel dryer can prevent the drum from rotating smoothly, affecting drying efficiency.
   Next: Adjust the leveling feet to stabilize the dryer.
5. Test the Heating Element
   Do: Use a multimeter to test the heating element for continuity.
   Observe: The heating element shows no continuity or is damaged.
   Means: A faulty heating element fails to generate sufficient heat for effective drying.
   Next: Replace the heating element if it is defective.
6. Inspect the Thermal Fuse
   Do: Locate the thermal fuse and test it with a multimeter.
   Observe: The thermal fuse is blown or shows no continuity.
   Means: A blown thermal fuse can prevent the dryer from heating, leading to prolonged drying times.
   Next: Replace the thermal fuse if necessary.

Common causes

Parts matching

Common parts needed for a slow drying dryer include:

• Lint filter (for cleaning or replacement)
• Vent cleaning kit (for unclogging the vent system)
• Heating element (if the dryer is not heating properly)
• Thermal fuse (to restore heating functionality)
• Adjustable leveling feet (to stabilize the dryer)

Before purchasing parts, test components like the heating element and thermal fuse with a multimeter to confirm the issue.

When to call a professional

• If the dryer still doesn’t dry properly after cleaning the lint filter and vent system
• If you are unable to locate or replace parts like the heating element or thermal fuse
• If the dryer is making unusual noises or vibrating excessively
• If you suspect gas leaks (for gas dryers) or electrical issues beyond basic testing
