What People Are Saying

Rated 1 out of 5 by from Terrible dryer I never take time to write product reviews, but that's how bad this dryer is. The dryer is not made very well, and the front panel is apparently not tightly connected to the dryer. It makes a creaking noise every time the dryer is in operation. Even worse, I stacked my dryer on the washer, so the dryer noise is even worse when the washer spins. It frequently displays d80 error message, even though there is no obstruction with the ducts. I bought LG based on reputation, but this dryer will certainly make me think twice before buying any LG appliance again.

Rated 5 out of 5 by from Great Features I bought this in November 2016 and I love it. I get laundry done faster because it is bigger than what I previously had. I like the options on it and have had no problem. I total recommend this product.

Rated 4 out of 5 by from great dryer, bad hook-up desogn Just received delivery and was not too happy to find the gas hook-up sticks straight out of the back making a potential for crushing or breaking the gas line. I suggest a 90-degree angle gas port like most other brands. Also, the dryer vent connection is a solid tube, making the redirection of the vent to rather side impossible without disassembling the dryer and purchasing a length of flex. I suggest the dryer vent port connection inside the dryer be substituted for a piece of flex hose so one can connect the dryer hose on either side of the dryer using the cutouts built into the housing. The stacking kit uses brackets which lock around the dryer's feet which is not secure when moving the unit around as the feet easily squeeze and lift out of the brackets. It's not a confidence-inspiring method of mounting, but it does keep a cushion between the washer and stacked dryer which is a nice compromise between stability and vibration isolation. Finally, the AC plug should also be a 90-degree plug like most other brands as the straight plug makes tight installation impossible because of the danger of breaking the plug or severing the cord. Apart from the design flaws which negatively affect installation, the feature-set is extraordinary for this price-fixing. The flow sensor is a nice feature and it ensures you must level the unit else the clothing may fall against the front door covering the vent and triggering the flow sensor. It is a great safety feature for lint build-up on the exterior house dryer vent as well. The rotary cycle selector is very easy to use and we shall see how it holds up to normal use. The multiple heat and cooling settings really accommodate varying drying jobs and I look forward to gas and electric savings. The signal chimes are a pleasant alternative to the old-style buzzer still in use on many other brands. The panel buttons and lights are nice and big and visible. The separator strips between the buttons insure against accidentally slipping and pressing the wrong button. The reversable door is nice because it ships installed opposite of the washer which is good for side-by-side but not for stacking. Finally, I wish the dryer had a direct-drive motor like the washer has instead of the belt drive common to most other brands. I look forward to at least a decade of use from this machine. Apart from these serious design flaws on the

Rated 5 out of 5 by from Quiet/Engergy efficent!!! Best on market Outstanding family dryer, user friendly functions, quite, with exceptional performance. Qualified for a rebate! Lowe's delivered and installed it free of charge. Wife is very happy with my choice and that is priceless!

Rated 4 out of 5 by from First Time user review So far my family and I have enjoyed the product. We only had some issues when installing it because we miss some packaging. The default drying setting are great for 1st time users but you will have to change them when you are doing a bigger loads or a more damp loads. Also, because this machine is front load you need to measure your space and the unit to make sure it will fit. These machines bows out in the front so I would recommend that you measure the unit from the center, the biggest point of the machine to make sure that it will fit in your space. Another thing is the hose in back of the machine, account for the space that you will need to accommodate that because it will push your machine forward. The hose is at the bottom which might not be the most convenient place for many people. Overall I like how it dries and how it lets you know when your clothes is done. So far so good. One last recommendation, leave the door slightly open so the unit can vent out and not smell moldy or dry out completely.

Rated 5 out of 5 by from Better efficiency than expected... I'm very happy with our new gas dryer from LG. It's efficient and quiet and has the ability to create a customized cycle, if needed. The price/performance of this dryer is hard to beat!

Rated 5 out of 5 by from Great features for the price. My wife and I always look for appliances that offer long term reliability and have the features that we like and need at the best price. We've had excellent luck with LG products in the past and that they are so highly rated by Consumer Reports only adds to that confidence.

Rated 5 out of 5 by from Great simple dryer I bought this on 12/2/16. My washer/dryer combo went out after 30 years! It was a transition to the front loader. Read the consumer reports and they had good comments about LG. I love the simplicity of the machine,performing well and saving energy. I am also getting a rebate! Very happy with my choice and would recommend to others.

What is the CFH or BTU/hr capacity? All I found is the pressure requirements.

The owner's manual only gives the BTU rating for the ENERGY STAR® Qualified LG 7.4 cu. ft. Ultra Large Capacity Dryer w/ NFC Tag On Technology, Model # DLG3171W as being AGA-certified for elevations below 10,000 feet. Regrettably, there aren't any listings for CFH or BGTU/Hr capacity.

How to light pilot light on gas dryer DLG3171W 

Asked by: Kim E
We appreciate your interest in this gas range. This model is not designed with a pilot light. When the knob for the burner is activated, this will start the use of an electric igniter to catch the gas and light the flame.

Dryer is making fire alarm go off and I would like to turn off the steam function associated with dryer. Would just like to use heat only thru vented duct and take away problems with condensation on closet door ( I have to keep closed so fire alarm off

Asked by: Jefd
We regret the inconvenience you have experienced during the use of this dryer. Generally, the STEAM options have to be activated manually before they are used. To prevent any such usage, you might attempt to utilize the TIMED DRY function, rather than one of the other presets.

I just purchased a DLG3171W dryer, had it for 2 days. Heat comes on in DELICATE position only, regardless of load. Heat does not come on at all in cotton, bulky, or perm press. Is this defective, or could this be a factory setting issue?

Asked by: sks6221
We regret the trouble you have experienced with this gas dryer. The heat should be active in the LOW HEAT function for Delicates and Permanent Press. It should be higher on most other settings except for the Air Dry cycle. If this is not the case, then the unit will need to be checked by a qualified technician. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at

How do we switch from the back to the side vent?

WE have bought this dryer and it will be delivered soon. We are wondering now about venting it out the side. If we buy the side venting kit, can we switch it ourselves or have our contractor do so? How easy is it to switch to a side vent?
Asked by: AngBla
Hello AngBla. Congratulations on your new LG 7.4 cu. ft. Ultra Large Capacity Dryer w/ NFC Tag On Technology, Model # DLG3171W. Thank you for choosing an LG Dryer. In the owner's manual for the DLG3171W are explicit instructions on how to change the vent location for the dryer. You may want to contact your contractor and ask if he/she will be able to change the vent location for you. If you are looking to do it yourselves, depending on your skill level and if you're adept with tools, changing the vent location is a fairly easy process...^IFV
