go behind the dryer, where the heating elements are located. turn the dryer on and feel for heat, if there is heat, turn off the dryer and unplug. with a screwdriver, remove the cover and you will see alot of lent everywhere, vaccume all of the lent from the coils area and clean out the dryer vent, going to the outside of the house. put cover back in place and restart your dryer, its worked several times for me. now i do this about every two months, just to be safe from fire hazards
