Is the lint screen clogged with lint?
• Dryers need good air movement to correctly operate. A full lint screen reduces air movement. Clean the lint screen before drying every load.
Is the exhaust vent or outside exhaust hood clogged with lint and restricting air movement?
• A clogged exhaust vent system slows moist air from leaving the dryer and extends drying time. Run the dryer for 5-10 minutes. Hold your hand under the outside exhaust hood to check air movement. If the air movement is less than a hair dryer on high speed, clean the lint from the entire length of the system and the exhaust hood.
Is the exhaust vent kinked, smashed or crushed?
• Kinked or crushed exhaust vent material slows moist air from leaving the dryer and extends drying time. Replace any plastic or metal foil vent with rigid or flexible heavy metal vent.
• The exhaust vent system may be too long or have too many turns. Heavy rigid metal vent material and boxed or louvered exhaust hoods allow for the longest exhaust vent systems. Use the fewest number of elbows for the best airflow. Your installation should not have more than 4 elbows. Each additional elbow in the system reduces the amount of vent material length the system can have for good air movement.
Are fabric softener sheets blocking air flow?
• A dryer softener sheet may be blocking the air intake or exhaust grille inside the dryer drum. This slows moist air from moving out of the dryer, which then lengthens the cycle time. Use only one fabric softener sheet per load, and use it only once. Remove any fabric softener sheets from the inside of the dryer drum.
Is the dryer located in a garage, on a porch or in a room colder than 45°F (7°C)?
• The air temperature surrounding a dryer in a garage or on a porch may be too cold for the dryer to dry loads well. Proper operation of the cycles requires the dryer to be in an area where the air temperature is above 45°F (7°C).
Is the dryer located in a closet?
• Closet doors must have ventilation openings at the top and bottom of the door. The front of the dryer requires a minimum of 1″ (2.5 cm) of airflow space, and, for most installations, the rear of the dryer requires 5½” (14 cm).
Were you drying a large load?
• Large loads take longer to dry. A load that is too large for the dryer will not tumble and limits air movement in the dryer. This slows the process of removing moist air out of the dryer, which will result in longer drying cycles.
