If your KitchenAid dryer smells like burning, start with the usual suspects: a clogged lint filter or venting packed with lint that restricts airflow. Excessive lint is the most common cause and can ignite near the heating element. Next check the drive belt; a stretched, frayed or slipping belt will rub and produce a hot burning odor, and while you’re in there confirm the drum and idler pulley turn freely. Electrical faults on the main control board are less common but important; a shorted component or scorched board gives off a chemical burning smell and should be inspected and replaced if you see burn marks. Some models use a blower belt or blower wheel, and a stuck blower or slipping blower belt will overheat and smell. If the idler pulley or idler assembly is seized the belt will slip and create heat and odor.
