- Is the dryer to close to the wall?
The standard flex hose is 4" diameter. You need that much room behind the bottom back of the dryer. Make sure
the flex hose isn't crushed and has a full 4 inches. - Is the flex hose too
long?
The hose should only be 2' to 3' long in most cases. They usually sell new hose in 8' to 20' lengths.
Be sure to trim the excess length so the hose doesn't "snake" around behind the dryer.
-Do you have adequate hood clearance outside?
Low level exterior vent hoods should should have
6" to 8" minimum clearance from the ground, landscaping, decks, patios, etc. to vent properly.
-Does your dryer vent have a screen?
Only fairly large opening screens should be used on the
exterior dryer vent hood and should only be used if you suspect birds or animals will nest in the duct. Window screen or wire
mesh (like rabbit cage screen) is too small. Lint will bridge and plug up the screen quickly, causing long drying time, moisture
condensation inside duct, dryer breakdown, even fire.
