Hi,

DW80K5050UG

I found DW80K5050UG/AA-00

There is often a fan in the vent inside the door that comes on near the end of the cycle......but the parts breakdown shows a fan housing but no fan, thankx Samsung

I did find a "fan motor" but it had no picture.......good luck with your repair

Thank you for the info, Jeff
