What people are saying
Rated 2 out of 5 by from Great Initial look/performance is fading I bought this unit in 2011 because of its features and LG. Now the plastic knobs are cracked (just use, not abuse) and even the control surface black decals are fading even though they were mildly cleaned. We just purchased an LG refridgerator and hope it holds up much better than your gas cooktop has. Very disappointed!

Rated 5 out of 5 by from Perfect Promise from LG Hey I'm a single guy ... and I have mentally struggled with forking over the cash - my old cook top was okay - it works - it cool looking. Nope. Trust Me - it's time and my suggestion is LG the LCG3091ST is awesome excellence in engineering. It's quick~HOT, my kids think it the new cool thing to cook on, and WOW my Pots and Pans are crazy~fun to cook with compared to what I thought was cooking before. COOL Blue lights are even awesome in the dark, perfect for turn me off, the five burners is nice addition, and LOVE the Stainless Steel look. It's what I would call the Perfect Promise from LG - delivered. Cheers to LG ... Donald in Sunny California

Is there any way to refinish the stainless steel surface of my 30" LG gas cooktop?

My cleaning lady probably used Brillo instead of the plastic and gentle brush she was supposed to to clean the area around the burners. There are light scratches in all directions on the whole surface.
Asked by: Andy3
We regret the inconvenience you have experienced with this gas cooktop range. Unfortunately, there is no method available to re-finish the stainless steel. The only option that might be recommended would be to use a Stainless Steel polish that might buff out any light scratches.

How far below the top of the counter surface does this unit extend?

Somebody asked a similar question, but the answer did not really address the question. The answer said the unit extends 3 3/4 inches below the "cabinet," which is difficult to interpret. The answer says this measurement does not take into account the actual depth of the surface. What does that mean? Obviously, the top of the counter surface is where the unit rests, so I need to know how far below the top of the counter surface the unit extends so I can tell if the drawers will allow installation of this unit. Thank you
Asked by: RalphF
3 3/4" from the top of your counter surface. Please take a look at the attached diagram: E = 3 3/4"

Is there any type of collar for 30-inch cooktops?

The cooktop I want to replace is 32-inches in width. I do not have enough room to enlarge the opening for a 36-inch cooktop, so I need to get a 30-inch one. Do you make or know of any kind of collar that can go under it to use the 30-inch one? (Counter top is limestone)
Asked by: MartyC
As it turns out, LG does not offer a trim kit for cooktops, sorry for the inconvenience.

Don't have 2 3/4 inches from cutout to the back wall

We bought this cooktop and found that our counter is a little tight for the size. We can fit it in, but will be within the 2 3/4 recommendation for the distance between the back of the cutout and the back wall. If we install it, the distance will be more like 2 1/4 - 2 1/2 inches. So, the question is whether this is within the "danger" zone, or if we can get away with it (the back wall is tile). The alternative is to get something with a smaller depth, but I don't see anything offered like this from LG. Thanks, Chad
Asked by: ellistrator
We appreciate your interest in the proper installation of this gas cooktop stove. For the 30” cooktop, the minimum distance, between the cutout and the back wall, must be 2 3/4". The reasoning for this appears to be the overlap of the cooktop onto the countertop, as well as the heating area for a gas stove.

What size gas line is required for the LCG3091ST cooktop

What type of connection is needed from the gas line to the uinit? Is it threaded or compression? Where is the connection located on the cooktop? How much clearance is required above the cooktop to the underside of the microwave oven?
Asked by: Jayzee
MATERIALS YOU MAY NEED • Gas line shut-off valve • To reduce the possibility of gas leaks, apply teflon tape or a thread compound approved for use with LP or Natural gases to all threaded connections. • Flexible metal appliance connector (5/8” I.D.) A 3-foot length is recommended for ease of installation but other lengths are acceptable. Never use an old connector when installing a new cooktop. • Flare union adapter for connection to gas supply line (3/4” or 1/2” NPT x 5/8” I.D.) • Flare union adapter for connection to pressure regulator on cooktop. (1/4” NPT x 1/2” I.D.) • Liquid leak detector or soapy water. 30˝ minimum clearance from countertop to unprotected overhead surface (overhead cabinet). Please see more details inside the installation manual: http://www.lg.com/us/support-product/lg-LCG3091ST Thank you, have a great day!

LED on Center knob won't turn off, but gas is off. Should I be worried? How do I fix this?

It's on the LCG3091ST. The center knob. The other knobs do not have this issue. The burner still seems to work as it should.
Asked by: DannoG
We regret the trouble you have experienced with this cook top range. The situation you have described could either be a broken knob, or a deeper problem with the range controls. If this is the case, then the unit will likely require service. 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 http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.

Concerning the size of the cut out

The current cut out of my granite countertops as 29.25. If the overall width of the top is 30", will this be a problem - In other words, will the unit buckle if it lacking the additional .75 inches?
Asked by: throck98
Cutout (LCG3091ST): Width 28 1/2” Depth 19 11/16” Please contact LG Customer Service at (800) 243-0000 or visit the support section of our website at www.LG.com/us/support for assistance.
