What People Are Saying

Rated 5 out of 5 by from We like the (4) different sized burners We recently purchased a 30 year old home we knew we needed new appliances ... LG has a great customer rating so we went with a suite purchase. When we removed the old "Electric Range" we found that there was a gas stub - we had gas! This was what we wanted - we found this LG Gas range and we are very pleased. This range fit perfect and the suite of new Stainless Steel LG appliances look great!

Rated 1 out of 5 by from HEAVY BLACK SOOT When using the oven or broiler on this model so much heavy black soot was produced that it coated every thing in my kitchen with a heavy layer of very black soot.

Rated 5 out of 5 by from I love this stove with one small exception if I could change one thing it is the plus/minus push to set the temperature on the oven; this is really annoying when setting the oven to a higher temp. Other than that one issue, I love this stove. The grill top; the blue interior oven; everything else is great.

Rated 3 out of 5 by from There is no Broiler pan The look is great and it is simple to use. When I pulled the bottom storage drawer out it felt very light weight and kind of flimsy. I then read the user manual. It told me to be sure and use the broiler pan when using the broiler so the grease could go down in the slits in the top of the broiler pan otherwise broiling could cause a fire. I go to check and look at the pan and surprise, surprise there was no pan. I spent the next day on the phone looking into it and getting the run around before I was told that it did not come with a broiler pan.

How do I get rid of the black soot.

I keep getting lots of heavy black soot coating every thing in and on my oven when I use the oven or broiler. What can I do to get this to stop? I've tried the cleaning cycles multiple times and it is still like cooking with coal.
Asked by: g1v3up
We regret the trouble you have experienced with this gas range. If all cooking cycles produce this soot, and it is not limited to one method or another, then it is recommended to ensure that the gas supply is clean, and that this soot is not from burning impurities in the gas.

Power Requirement

Does the oven come with the 120v power cord? Is it just a standard plug? Thank you

do you offer a cooktop burner catch tray?

a catch tray surrounding the burners to catch spills and boilovers would be great. is this an accessory?
Asked by: tla1
I apologize, but no; such an accessory is not available for this gas range. We can only recommend cleaning up spills as soon as possible.

Why is it that I keep getting an "error" light when I try to bake?

I can only broil in my oven. Why can't I bake? I press bake punch in the the temp. then set the timer and I press start and it says error. Even if I press bake and just set the temp that I need and press start it says error. I can only broil on this range. Please help!
Asked by: Baker
We regret the trouble you have experienced with this range. That which you have experienced is certainly not normal operation. In order to determine the cause of this error message, 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

What is the temperature range of the oven?

I bake bread and my current oven has a proofing function which keeps the oven at 100 degrees fahrenheit. I am also able to dehydrate as well. Does this model have these capabilities?
Asked by: breadbaker

How high from the ground are the bottom and top edges of the handle bar?

Please provide heights of both bottom and top edges.
