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). See the Installation Instructions for details. Were you drying a large load? Large loads take longer to dry.
