A:Answer10 yrs for the motor from the manufacturer if I understood correctly. The rest I believe it has a one or two year warranty (?) , but you can buy extra warranty if you wish to do so.
A:AnswerThe power cords for both the ENERGY STAR® Qualified LG 7.4 Cu. Ft. 8-Cycle Gas Dryer with FlowSense™ - White, Model # DLG3401W and its matching washer are about six feet long...^IFV
A:AnswerYes.
Old Pedastal: WDP3W. - time to install 2-3h
New Design: WDP4_ - time to install 30 min
The difference is that the WDP4 is made to be reinstalled on a new product. As soon as you try to take off the old dryer from WDP3_ you will realize why they had to redesign it. It uses foam double sided tape to attach to the dryer without damaging it presumably because the old dryers were not made to receive pedestal.
You will have use a chisel and mallet to remove the plates then to reattach, get self-drilling machine screws 8 (10 just in case about $0.15 each), #8 1/2 inch for example. Power drill needed. (use eye protection) It will 'damage' the new dryer so consider buying the upgraded Pedestal if that is important, especially if you want it to match. It's not cheap though. You could remove the foam tape and buy 3M flooring tape after removing the old adhesive but that would be a time consuming process. I estimate with the chisel and goo-gone or vinegar soak it would take 2 hours oif labor (use nitrile gloves).
Refer as well to the install instructions for WDP3_
