This was ALMOST the right part for my Samsung DW80J3020US, same general switch but slightly different mechanism. The electronics connected in the same way, and it seemed to fit just fine, but when I tried to run the cycle, it just beeped like the door was still open. It turns out the I switch needs a little more room to fully open, so I just backes out the screws on the door panel a little to give the switch more room. That worked! So the secret is: Don't screw it everything down too tight!
