I'm sorry to hear you're having this issue with your DV220 dryer. There are a couple of factors that can effect the ability of the sensors to work correctly and dry thoroughly. First, check to make sure the lint trap and housing are clean and the vent ducts are not clogged. Next, wipe down the sensors located on the inside surface of the lint trap area (just below the door opening). A build up of lint and debris in these areas can effect the ability of the sensors to work properly. If you're drying a mixed load, it is not unusual for heavy, damp items to migrate to the rear of the drum, away from the sensors, which would then detect only the dry, lighter weight items at the front. If you're drying a mixed load, Samsung recommends using the Time Dry settings. If the load is not mixed, the lint filter, housing and ducts are free of lint build up, and your dryer still shuts off early when set on an appropriate Sensor Dry setting, it may require service. To initiate service through Samsung, please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
