Craig Y Fairfax , VA October 13, 2018 Appliance: Model DV5451AGW/XAA 03 Dryer was running and would not shut off except if you unplugged it or opened the door no heat I Google searched the problem and saw several videos advising that the problem was the PCB board and showing exactly how to replace it. Because of the video I knew how to access the PCB board and replace it and felt very comfortable that I could do the repair. Because of the videos I was able to temporarily get the dryer back working. I found and ordered the part from AppliancePartsPro.com and it came very quickly. The repair took approximately 10 minutes and that was me taking a lot of time to make sure I was taking pictures, carefully disconnecting the wires etc. The only tool I needed was a phillips screwdriver. I am REALLY tired of calling an appliance repair guy, having he or she diagnose the problem, have to order the part, having to come back and $350.00 and 3 weeks later hopefully having a working appliance. For what it is worth I would NEVER buy a Samsung washer or dryer (again), We bought a washer and dryer about 5 years ago and we finally gave up on trying to fix the washer (couldn't get parts) and NO dryer should fail where it keeps running! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
