Our Samsung DV42H5200GW/A3 dryer has a large crack and hole in the back of the drum and it is making a loud sound.....like there's a shoe in the dryer. After reading all of the issues regarding this specific problem, and lack of company support, I am deeply regretting our decision to purchase this brand. I would like to replace this part and avoid the high cost of a new unit, if possible. I need to know what the part number is though, in order to replace it. I have tried google, but get conflicting part numbers. Unless samsung somehow comes through in an amazing way, this will be our last appliance purchase from them.
