The FAD504DWD is an older FAD-series dehumidifier that is well past warranty in most homes. At this age, reduced water collection and control failures are common, and the economics of repair versus replacement need an honest look.
Any burning smell, scorched or discolored plastic, or a hot power cord is a safety warning: unplug the unit immediately and do not use it again until it has been inspected. Some older dehumidifiers have been subject to safety recalls, so check your model and serial number with the manufacturer and the CPSC recall database.
