Most common issues on this model
- Dual burner lighting on only one ring
- LED knob light not matching burner status
- Weak or uneven flame at the large burner
- Igniter that keeps clicking
The CBGJ3027S is a 30 in LG gas cooktop with an UltraHeat 22K BTU dual burner, continuous cast iron grates, and a removable griddle. White LED knobs show which burners are on, and the ThinQ app adds smart features. It is a current model.
A dual burner has two flame rings, so we check that both light and burn evenly. We also clean and reseat the burner parts, test the igniters, and look at the LED knobs and the app connection if either is behaving oddly. Because the griddle and grates add weight, we also confirm each grate foot sits correctly so pans do not wobble over the flame.
Nothing is ordered until the label confirms your exact model and serial. A written price comes before the work, and our repairs carry a 30-day workmanship warranty.

Error codes this model can show
Why does only the inner ring of my dual burner light?
The outer ring may have blocked ports, a seating problem, or a weak spark. We clean and reseat the burner and then test each igniter.
The knob light is on but the burner is off. Is that a problem?
LG describes the LED knobs as showing which burners are on. If the light and flame disagree, we check the knob switch and its wiring.
Can I still use the griddle if the burner needs repair?
The griddle sits on the grates, so we remove it during service. We test the burner flame with the griddle off and confirm everything seats properly afterward.
