Confirm you're choosing a cycle that uses heat to dry clothing. Cycles like Air Dry or Air Fluff don’t use heat, and may take longer to completely dry clothing.
2. Make sure there's no lint blocking the exhaust vent (located on the outside of your home).
3. Check to be sure the vent hose running from the dryer to the wall isn't kinked or crushed. If the hose is damaged, replace it with a rigid metal or rigid flexible hose (as opposed to vinyl or foil).
4. Double-check that your vent hose is as straight as possible and no longer than 25 feet. If the hose has any 90-degree turns, it should be no longer than 20-feet because the turn can restrict airflow and increase drying time.
5. For gas dryers, make sure the gas is running properly. An easy way to identify a gas supply issue is to check another gas appliance in your home:
* On Gas Ranges - Turn on burners to see if they light.
* On Water Heaters - See if pilot light is lit.
* On Gas Furnace - Turn on Furnace, set to 80° and check for heat coming from heater vents.
