What is the most common problem with Samsung dryers is not heating or not drying clothes properly, often caused by failed heating element, thermal fuse, or clogged vent. Many Samsung dryer owners report dryer runs but does not produce heat, leaving clothes damp, error code HE or HC may appear. Cause is heating element coil breaking after 2 to 4 years, especially with frequent high heat use, replacement part DC47-00019 costs $30 to $50 DIY. Second common problem is thermal fuse blowing due to overheating from clogged lint filter or vent duct, causing no heat, fix by cleaning vent and replacing fuse $20. Third common is loud squeaking or thumping noise from worn drum rollers, idler pulley, or belt, requiring replacement $20 to $50 parts. Fourth is control board failure causing dryer not to start or random shutting off. Fifth is moisture sensor dirty causing clothes still damp. Overall not heating is most common complaint in reviews, often due to heating element or vent blockage, fixable with cleaning vent yearly, cleaning lint filter after each load, and replacing heating element. Prevent by not overloading and cleaning vent duct annually.
