Kerri K Cedarburg , WI September 26, 2014 Appliance: Samsung Dryer DV407AEW/XAA-0001 Samsung Dryer Dv407aew/Xaa-0001: Dryer tumbling but no heat heating element failure. How to replace Dryer Heating Element Assembly. Replaced the heating element assembly. Chose to replace the whole thing as there was burnt areas on the box from lint and both my washer & dryer get used a lot!!!! I watched a youtube video to take the old one out and drop the new one in. Took maybe 1.5 hours as I disassembled the lint catcher & cleaned the lint out the inside of the dryer box. $aved money vs. call repair guy. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
