Bravo gas dryer takes too long todry clothes

Taking too long can be very difficult to troubleshoot because term is quite relative. A load of bed linens will dry much quicker than a load of jeans.

Check your dryer vent (usually outside) to see if a bird or critter has made a home. Then check your vent hose. Same thing, look for buildup of lint here. Check your filter as well. See if there has been any lint that has built up and fallen off the filter (look down in tube, holder, etc).

Since dryers use room air to circulate with, and then expel it outdoors, also make sure that there is adequate air flow to the dryer. Open a window in same room, if you can. If it improves, then your house is sealed up tight (and that's the problem).
