Rusty G Raleigh , NC March 06, 2015 Appliance: Samsung Washer WF448AAP/XAA-0000 Samsung Washer Wf448aap/Xaa-0000: There was no power on the digital screen of samsung vrt front load washer. How to replace Washer Control Board. I researched the problem on the internet. Using the Samsung model number (WF448AAP/XAA) I was able to determine that the most common reason for this issues is the Assembly Pcb Sub panel is bad. I purchased the part (DC92-00130A (AP4455125)) from AppliancePartsPros, It was comforting knowing that if this did not fix the issue I could return it. The sales person I spoke with even provided me with a Training Manual and Fast Track Trouble Shooting Guide for my washer. I received the part the next day and within 5 minutes the washer was back up and running. 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
