Appliance Parts Pro was the only company I could find that offered detailed exploded drawings of the Samsung Gas Dryer. The drawings helped me locate the suspect components in the heat control system without completely disassembling the dryer. They also had the necessary parts in stock. Heat problems are difficult to track down because a balance of temperature must be maintained for the dryer to work properly. Anything from a malfunctioning sensor to air flow issues can upset the balance of heat transfer and cause the dryer to not work properly.
