What people are saying

Rated 5 out of 5 by from Easy to use! So many great features and easy to use. Automatic sensing and displaying the time remaining sure helps keep laundry done.
Date published: 2022-05-14
Rated 5 out of 5 by from Only 4 months old BUT "one" of the BEST! This dryer (the other half of a LG stackable unit) was a welcomed replacement for a 6 yr old GE stackable washer/dryer unit that literally QUIT (master circuit board) only after 6 yrs of "normal" use! The new LG model is miles apart (efficient features, quality, ease of use & having results expected) from our previous GE model! If you "expect" the best from your dryer, this LG unit is DEFINITELY the one for you!!

Rated 5 out of 5 by from Fantastic Dryer! Bought this dryer with the matching washer about a month ago. All the drying options are great. This is our first electric dryer and electric drying is different than gas, so we had to get used to that. Love the design.

Does the black color and appearance match with the new washer model WM4000HWA? Currently the DLEX4000B is not available at my zip code.  Is there any way to order DLEX4000B and deliver when it’s available?

Asked by: JanetSF
I can only confirm that both dryer DLEX3900B and washer WM4000HBA both are Black Steel. I cannot say whether or not there is variance in color appearance. ^Daphane

What is the length of the electrical cord? Where is located on the dryer (top or bottom)?

Asked by: Guest123
Electrical Dryers do not come with electrical power cords. They have to be purchased separately. The Terminal Block Access Panel that you have to connect an appropriate power cord to on the ENERGY STAR® Qualified LG 7.4 cu.ft. Smart wi-fi Enabled Electric Dryer with TurboSteam™, Model # DLEX3900W is located in the top right corner (If standing behind the dryer. left if standing in front of the dryer) of the cabinet. The wiring and grounding must conform to the latest edition of the National Electrical Code, ANSI/NFPA 70, and all applicable local regulations. Depending on your local building codes, you can use either a 30-amp, 240-volt, 4-wire, UL-listed power cord with #10 AWG-minimum copper conductor and closed-loop or forked terminals with upturned ends, or a 30-amp, 240-volt, 3-wire, UL-listed power cord with #10 AWG-minimum copper conductor and closed-loop or forked terminals with upturned ends. A 3-wire connection is NOT permitted on new construction after January 1, 1996. A 4-wire connection is required for all mobile and manufactured home installations, as well as all new construction after January 1, 1996. If you are not sure which power cord is required in your home, check your local building codes or contact your local building inspector. You can select the length of the appropriate power cord you need from the retailer that you purchase the dryer from...^Ivan

What is the total height with a pedestal. Or can you just add the heights listed?  

Asked by: Cobblestone
When you install the 27" LG Laundry Pedestal, Model # WDP4W under the ENERGY STAR® Qualified LG 7.4 cu.ft. Smart wi-fi Enabled Electric Dryer with TurboSteam™, Model # DLEX3900W, the leveling feet on both units have to be lowered to their lowest setting which are the listed heights for each unit, so you can just add the listed heights for either unit to get the total height for when you have the pedestal installed under the dryer. That will be 14 1/8" for the pedestal and 38 11/16" for the dryer which will be a total height of 52 341/400" if you prefer fractions or 52.8025" if you prefer decimals...^Ivan
