LG vs Samsung Cooktop
LG's UltraHeat burner delivers the highest gas BTU output in the mainstream class, while Samsung's Flex Cooktop is the most innovative induction design, with a virtual-flame indicator. For raw gas cooking power choose LG; for cutting-edge induction choose Samsung; repair costs between the two are comparable.
These two Korean brands push cooktop technology harder than most, but they specialize in opposite directions. LG's flagship feature is a high-output gas burner for cooks who want to sear and boil fast. Samsung's is an induction surface that rethinks how zones work. Your fuel preference does most of the deciding here, so start there and the rest falls into place.
LG vs Samsung cooktop — side by side#
| Factor | LG | Samsung |
|---|---|---|
| Gas standout | UltraHeat high-BTU burner (up to 22,000 BTU) | Strong, not class-leading |
| Induction standout | Solid induction lineup | Flex Cooktop with virtual flame |
| Best for | Gas cooking power | Induction innovation |
| Repair cost | Varies (comparable) | Varies (comparable) |
| Common repairs | Igniters, valves, elements | Induction boards, touch controls |
Verdict: choose by fuel type — LG for gas muscle, Samsung for the most advanced induction.

LG owns gas power#
If you cook on gas and want heat now, LG's UltraHeat burner is the headline. Rated up to 22,000 BTU on its highest-output models, it brings a large pot to a boil quickly and delivers the aggressive sear that serious home cooks chase. The rest of the LG gas cooktop is well-executed too — sturdy continuous grates, precise low simmer on the smaller burners — but UltraHeat is the reason gas-first buyers put LG at the top of the list. Samsung's gas cooktops are perfectly capable, just not built around a single standout high-power burner the way LG's are.
Samsung owns induction innovation#
Flip to induction and the lead changes hands. Samsung's Flex Cooktop lets you combine zones into one large flexible area for oversized pans or griddles, and its virtual-flame feature projects a light onto the pan to show heat level at a glance — a clever answer to the old complaint that induction gives no visible cue. It is the most forward-thinking induction surface in the mainstream market. LG makes good induction cooktops as well, but Samsung is the one pushing the format's boundaries, so induction-curious buyers usually end up there.

Repair costs are a wash#
On service cost, neither brand has a meaningful edge — repairs run comparable across the two. What differs is what breaks, and that tracks fuel type more than badge. Gas cooktops from either brand see igniter, spark module, and gas-valve issues, all relatively inexpensive and quick to fix. Induction models concentrate their failures in the power boards and touch-control glass, which are pricier components. So the more your repair bill depends on your choice of gas versus induction than on whether the nameplate reads LG or Samsung.
Common cooktop repairs#
A few failures dominate the service list. On gas, a burner that clicks but will not light is usually a dirty or cracked igniter or a wet spark module — often a cleaning rather than a part. On induction, an error or a zone that will not heat points to the power board or a failed sensor under the glass. And on any glass-top, a cracked surface from a dropped pan is a real repair on both brands. Keeping the surface clean and the burners dry prevents a surprising share of no-heat calls regardless of which you own.

Cookware, installation, and everyday care#
One practical difference shapes daily life more than any spec: induction demands magnetic cookware. If your pans are aluminum, copper, or a non-magnetic stainless blend, a Samsung Flex Cooktop simply will not heat them, so factor a possible cookware upgrade into the cost of switching to induction. Gas is indifferent to your pots, which is part of LG UltraHeat's appeal for cooks who do not want to rethink their kitchen. Installation differs too — a high-output gas cooktop needs adequate gas supply and ventilation, while a powerful induction surface needs a suitable electrical circuit, so check both before you commit. On upkeep, both reward a clean surface: wipe spills before they bake on, keep gas burner ports clear so the flames stay even, and never slide heavy cast iron across an induction glass top, which is the fastest way to scratch or crack it. A little care here prevents more service calls than any brand choice ever will.
Repair or replace#
The 50% rule settles it. If a repair quote passes 50% of a comparable new cooktop and the appliance has used about 70% of its expected life, replacement is usually smarter. Igniters and valves are cheap enough that gas cooktops are almost always worth repairing; it is a failed induction power board on an older unit that most often tips the math toward a new cooktop.

Which should you buy?#
Let fuel lead. If you cook on gas and value high-output searing and boiling, LG's UltraHeat makes it the clear pick. If you want induction — and especially the flexibility and visual feedback that address induction's usual drawbacks — Samsung's Flex Cooktop is the standout. Repair costs will not decide this one, so choose the cooking experience you want and buy the brand that does it best. Think honestly about how you cook most nights — a fast, hot sear or a precise, responsive simmer — and let that daily reality, not a feature list, make the final call.
