Replacement and Cleaning

Replacement and Cleaning

To replace the knobs, make sure the knob has the "OFF" position centered at the top. Slide the knob straight off the stem and slide the replacement knob back onto the stem. Do not bend the knobs upwards or downwards, and do not hang towels or other objects on them as this can damage the gas valve shaft. Same process can be used for easy cleaning of the knobs.

It is also best to clean the front panel after each use of the range, stove or cooktop. Use a damp cloth and mild soapy water or a 50/50 solution of vinegar and water. Rinse with clean water and polish dry with a soft cloth.

NOTE: Do not use abrasive cleansers, strong liquid cleaners, plastic scouring pads, or oven cleaners on the manifold panel. They will damage the finish on your range, stove or cooktop.


What People Are Saying

Rated 1 out of 5 by from Terrible quality So, I have read all the reviews. Bought a beautiful cooktop and they have cheap, plastic knobs that melt and crack then you charge a fortune for a replacement. Shame on you. Given the fact that ALL your responses state you will send off to someone else for suggestions is a worthless response as you haven’t done anything about it! I spent a small fortune updating my entire kitchen with high end LG appliances but when I need to replace in future I will certainly think twice if you can’t get the details right.

Rated 3 out of 5 by from cheap plastic knobs We have had this stove top for three years and the knobs started cracking then break, I replaced two of them and now its time to replace the other three, my last stove top lasted ten years with no knob problems and it was priced in the same range no pun intended.these knobs cost ten percent of the cost of the top?

Rated 1 out of 5 by from Very poor quality and low grade material I purchased these knobs multiple times in the past 2 years. Plastic used for these knobs is really fragile and breaks at the base. LG has to fix these knobs.

Rated 2 out of 5 by from love the cooktop, hate the knobs We love our cooktop and separate griddle that we are able to place on top of our burners. Fabulous dual purpose and we are able to tuck away the griddle; however, who designed plastic knobs for a gas cooktop? In reading the reviews on these knobs after we purchased the cooktop, we had no idea they were plastic, and secondly, we had no idea these plastic knobs were so expensive per knob. Why haven't these knobs been changed yet? They eventually melt!!! It makes a beautiful high end cooktop look cheap. I am still going to recommend the product but sure hope the design team will make a change soon. I'm happy to join your design team to help escalate these suggestions to more of a priority!

Rated 1 out of 5 by from Great cooktop marred by cheap knobs. We love the cooktop but the design has the plastic knobs too close to the heat and the insert melts and becomes discolored. I have seen past reviews where you say it is being referred to company designers. Some of these reviews are over two years old and I am wondering before I buy another set of knobs if the quality issue has been dealt with or is it just a profit center for LG.

Rated 1 out of 5 by from Break easily - why would LG create poor quality? Same as everyone else: plastic breaks easily. The cooktop is wonderful (after 4 years of use). Why would LG create such a poor design for an otherwise outstanding product? And why can they not fix the problem? Seems like replacing the plastic end with metal would not be that hard. Or, if cannot be fixed - at least drop the price!

Rated 1 out of 5 by from These are absolutely horrible!!! We are on the 5th set of knobs for our cooktop!! This is ridiculous!!! If you are going to build them cheap, then price them cheap. I just do not understand how you would build such a beautiful product and then insult it with such cheap window dressing. I will not recommend this soley on the poor quality of the knobs. It is so frustrating!

Rated 1 out of 5 by from Break easily These knobs frequently break and are 24 per knob. Terrible quality for the cost.

Rated 1 out of 5 by from Terrible plastic design breaks. We bought an LG gas cooktop with this type of knob. DO NOT BUY ANY GAS COOKTOP with this type of knob. You will end up buying multiple replacements knobs every year that you own it. We have had to purchase 4 replacement knobs in 2 years with normal use!!! They are plastic and break very easily.
