I'm sorry to hear you're having some difficulty drying a blanket in your DV330AEB. First, please check the lint filter and vent to make sure it isn't blocked. This is one of the most common issues that can prevent the dryer from running a full course. Even though the dryer is only a month old, if you used the previously installed vent duct or weather hood, there could be enough blockage to restrict air flow.
When running a Sensor Dry cycle, it can sometimes be helpful to add a few towels when drying larger items like sheets and blankets which can have a tendency to bunch up, preventing the sensors from being able to detect the moisture level in the dryer accurately. However, if the dryer is shutting off early when selecting a Time Dry cycle, and the power source and vents are all set up properly, your dryer 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.
