Only the inner ring of my LG radiant element works. Why?

Dual and triple elements have separate rings controlled by a switch or relay. If only the inner ring heats, the outer ring, its switch or the wiring has likely failed. We test each part and replace only what is needed.

One zone of our Marvin induction cooktop stopped working. Is the whole cooktop failing?

Not necessarily. Induction zones are often driven by separate boards or coils, so one zone can fail while the rest work. Check that your pan is magnetic and sits flat. If the zone still will not respond, we can test the board and coil behind it.

Can you repair a pro-style gas rangetop in a Waxhaw kitchen?

Yes. Pro-style rangetops are built to be serviced, and igniters, spark modules, valves and switches are replaceable. Some parts for these lines are ordered, and we tell you the timing before the visit ends.

LG Cooktops: What We Check First

LG cooktops come in three main forms: radiant electric glass tops, induction glass tops and sealed-burner gas. The radiant models often include dual and triple elements that switch between ring sizes, while the induction units use coils and power boards that regulate the magnetic field for each zone. Gas models use spark ignition and LG's UltraHeat high-output burners on some versions. Most are controlled by touch panels on the glass or front-mounted knobs.

Dual or triple radiant element ring failing to heat
Induction cooling fan or power board fault shutting zones off
Touch control unresponsive from residue or moisture on the glass
Scorched junction box wiring under the cooktop cutting power

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our LG cooktop repair guide.

Pro-Style Rangetops and Induction Surfaces

A separate cooktop is common in the larger kitchens around Waxhaw and Marvin. Gas models, including heavy pro-style rangetops with sealed or open burners, mainly fail at ignition: a spark module that clicks endlessly, an electrode cracked by a dropped pot, or a burner that lights only after several tries. Induction cooktops have no flame or hot coil, so their faults are electronic, such as a zone that will not detect a pan, a cooling fan that stops, or a power board that fails.

With everything turned off, remove the grates and caps, clean any boilover from the burner heads, and let them dry before trying again. For induction, make sure the cookware is magnetic and flat. Never touch the gas supply, and if you smell gas, leave the home and call the gas utility or 911.

Our technician tests the igniters, switches and module, or the induction boards and sensors, from the top or from beneath the counter. We explain the cause and give the price before starting. Island cooktops often have downdraft vents or tight cabinet space below, so the technician checks access before removing anything. Repairs carry a 90-day parts and 30-day labor warranty.
