A recent visitor to our workshop, this dryer was making a rattly sound. It turned out the peg had travelled all the way through the workings of the dryer ending up jammed up against the vent and making that fun chicka chicka sound you get when something is caught against a fan. Fortunately the technician was able to remove it with no harm done but that was luck; it may have caught in places where it might have caused a fire. So its worth checking to make sure only clothes are going for the merry-go-round in your dryer. This customer was also lucky, as there was a bamboo skewer caught in the filter as well
