This is a picture of the inside of a 3-year-old gas dryer. The vent duct was routed to exit the side instead of the standard rear configuration. In this case, the installation company simply taped the vent duct to the output of the blower housing. The problem was that the duct hose came loose and blew dust and lint all over the inside of the dryer. This created a fire hazard and caused the dryer to not work properly. In this case, it would heat for 4 minutes and then stop heating for an extended period of time, causing dry time to be exceedingly long.
