Dryer exhaust vents should be inspected and cleaned at least once a year depending on the size of the household and dryer usage
Dryer vents accumulate highly flammable lint, and failure to clean out lint is the leading cause of dryer fires.
A telltale sign that the dryer vent needs cleaning is that clothes take longer and longer to dry.
“When it takes 2-3 cycles to dry a load, it’s time to check things out.” Another indication of poor or obstructed venting is that the dryer’s external cabinet or it’s control area is hotter than usual. If that happens, disconnect the dryer and check the vent.
