Description
What the LG LCE3010SB Is
The LCE3010SB is a 30 inch radiant electric cooktop with a black ceramic glass surface and five elements. It drops into a countertop cutout and is controlled by SmoothTouch capacitive controls printed on the glass itself, so there are no knobs and nothing raised to catch spills.
Five elements on a 30 inch surface is a generous count. Most cooktops of this width offer four, and the fifth here is a dedicated warm zone rather than a full element, which is a sensible use of the space between the larger burners.
The Element Data Is Published In Full
This is the most useful thing about the listing and it is rare. LG gives every element with its size and its power rating: a dual element of 9 and 6 inches at 3.0 and 1.4 kilowatts, an 8 inch at 1.9 kilowatts, a 7 inch at 1.5 kilowatts, a 6 inch at 1.2 kilowatts, and a 6 inch warm zone at 0.1 kilowatts.
That level of detail lets a cook plan properly. The 3.0 kilowatt dual element is the one for boiling a large pot, and being able to switch it down to a 6 inch ring means a small saucepan does not sit on an oversized heated area wasting energy and scorching handles. The 0.1 kilowatt warm zone is not a cooking element, it holds finished food at serving temperature.
Added together the published element ratings come to roughly 7.7 kilowatts of connected load, which is why this is a 240 volt appliance. What the listing does not publish is the required circuit rating in amps, and that figure should come from LG’s installation manual rather than being calculated by a buyer. A licensed electrician should confirm or install the circuit before the cooktop is delivered, and an existing circuit left over from an older cooktop should not be assumed adequate.
The Cutout Is Published Too
LG gives both the exterior dimensions, at 30 and 27 thirty seconds inches wide by 22 inches deep by 4 inches high, and the countertop cutout at 29 and 3 eighths inches wide by 20 and a quarter inches deep. For a drop in appliance those cutout numbers are the whole planning exercise, and many listings omit them entirely.
The listing also states a right rear cable location. That sounds trivial and is not: it tells the installer where the connection has to be made and therefore where the junction box needs to sit in the cabinet below, which affects any drawer or shelf under the cooktop. Confirm the clearance required beneath the surface from LG’s installation manual, since a drawer directly below may need modifying or removing.
Controls And Cooking
SmoothTouch controls are capacitive, operated with a fingertip on the glass. The advantages are a completely flat surface that wipes clean in one pass and a centralized display showing which element is active. The trade off is that capacitive controls do not work through a thick oven glove and can be less responsive with wet fingers, which is worth knowing before committing to a knobless surface.
LG describes Steady Heat elements as delivering constant heat at any temperature setting with a quick response to adjustments. Conventional radiant elements cycle on and off to hold an average temperature, which is what makes low simmering awkward on a cheap electric hob. Whether this implementation improves on that meaningfully is a manufacturer claim with no test data attached, and it should be read as design intent.
Five hot surface indicator lights, one per element, address the real hazard of a glass ceramic surface: it looks identical hot and cold and stays hot long after the element is switched off. An auto shut off is also included, which cuts power if a control is left on with no cooking activity, and that is a feature worth more than most of the marketing on any cooktop listing.
A cooktop is also only half of a cooking setup. Anyone specifying one alongside a wall oven should check that the two are on separate circuits and that the cabinetry can take both, since a combination wall oven such as the LG WCEP6423F carries its own substantial electrical requirement in addition to this one.
Highlights
- Five radiant elements on a 30 inch ceramic glass surface.
- Full published element sizes and power ratings, including a 3.0 kilowatt dual element.
- Dedicated 0.1 kilowatt warm zone for holding food.
- Published cutout dimensions and cable location for installation planning.
- Five individual hot surface indicator lights and an auto shut off.
- SmoothTouch capacitive controls on a completely flat surface.
- 240 volt operation with a stated 1 year parts and labor warranty.
Things To Consider
The required circuit amperage is not published, and that is the one installation figure still missing. The specification table also records the installation type as freestanding, which is wrong for a drop in cooktop, and gives a wattage field of 1500 watts, which is one element rather than the appliance.
The dimension fields appear twice with different numbers, 34 by 25 by 7 inches in one place and 22 inches deep by 30.84 wide by 4 high in another. The second matches the description and is the one to use, with the first almost certainly being the carton.
This listing dates from 2010, which is worth noting in both directions. A platform sold for that long has a parts and service history behind it, and it also means the design predates more recent features such as bridge elements and connected controls.
Glass ceramic maintenance applies as it does to any smooth top: clean sugar spills while the surface is warm to avoid pitting, avoid dragging cast iron across the glass, and treat the surface as breakable under a dropped pan. A cooktop also needs extraction above it, so a hood should be planned at the same time from the range hoods category, with something like the FOTILE JQG7505 suiting heavier cooking. Buyers comparing surfaces will find the alternatives in the cooktops category, including the four element Frigidaire FFEC3025UB.
Who Should Buy It, And Who Should Not
It suits a kitchen with a 30 inch cooktop cutout and a suitable 240 volt circuit, where five elements and a warm zone are worth having and where a completely flat knobless surface is the preference.
It is the wrong purchase for anyone who wants physical knobs, anyone shopping for induction or gas, and anyone who cannot have an electrician confirm the circuit before installation.
