If your dryer takes too long to dry, start by checking airflow—restricted vents or a partially clogged duct are the most common cause and will slow drying, raise cabinet temperature, and can even cause a burning smell or dryer overheating. Next check the blower wheel: lint, socks, or a worn sleeve can block or let the wheel wobble, which cuts air flow. If airflow looks fine, test the heating element on electric models with a multimeter; a weak or failed element will make the dryer not drying clothes on time. On gas dryers a bad gas valve assembly or solenoid can prevent consistent heat—an igniter that glows but the burner never lights is a strong clue. Don’t forget the lint filter and housing: a clogged filter or residue from dryer sheets reduces flow and increases cycle time.

01 - Air Flow Problem
If the vent line is clogged or partially clogged, it will restrict the airflow through the dryer, substantially increasing the drying time and cabinet temperature and potentially causing a burning smell. To ensure proper dryer performance, you should clean your dryer's venting system at least once per year.

02 - Dryer Blower Wheel
The blower wheel works with the drive motor to draw air into the dryer drum. Clumps of lint, socks, and small articles of clothing can escape the lint filter and get caught in the blower wheel. In addition, the blower wheel sleeve can wear out, allowing the blower wheel to wobble on the motor shaft. If the blower wheel is obstructed or defective, it may take too long to dry clothes. To determine if the blower wheel is working properly, remove the dryer vent and assess the strength of the air flow. If the air flow is weak, check the blower wheel for obstructions. If no obstructions are present, try rotating the blower wheel... by hand. If the blower wheel wobbles as it turns, replace it.

A dryer's heating element is the component that heats the air being circulated through the dryer drum. If the heating element is failing, it may be unable to sufficiently heat the air to dry the laundry in the expected time. You can use a multimeter to test the element for electrical continuity to help determine if the component is faulty.
A dryer's gas valve assembly is the component that opens to allow gas to flow into the burner tube to ignite into a flame to heat the air being circulated through the dryer drum. A solenoid on the gas valve assembly can fail at any point during the drying cycle, resulting in the dryer taking too long to dry the laundry. An igniter that glows and goes out without lighting the burner is a good indicator the solenoid coil is bad. On some dryer models the gas valve parts are not sold individually requiring the whole gas valve assembly to be replaced.
A clogged lint filter will cause a loss of air flow, which can lead to long drying times and may cause the dryer to overheat, tripping the thermal fuse. For the best drying performance, clean the lint filter before starting the dryer and be aware that dryer sheets can cause residue to build up on the lint filter. If you cannot blow air through the lint filter it will need to be cleaned with a brush, soap, and water. Confirm the lint filter housing and grille, if applicable, are free of lint build up as well.

06 - Dryer Lint Filter
The lint filter might be clogged. Dryer sheets and fabric softener can leave a residue on the lint filter, reducing the air flow. If the lint filter is clogged, clean it. Confirm the lint filter housing and grille, if applicable, are free of lint build up as well.
