LSCG366ST
LG STUDIO LSCG366ST 36-Inch Gas Cooktop Repair

Most common issues on this model
- Burners that spark continuously or will not stop sparking
- Flame size on the stacked center burner
- Knob switches and spark module response
- Gas connection and regulator condition
The LSCG366ST is the 36 in version of the LG STUDIO gas cooktop and is now an older model. A wider top usually means more cooking room in a kitchen with a longer counter run, and the gas feed and any hood overhead matter as much as the burners.
Its dual stacked center burner and large knobs are the features we spend the most time on. A burner that keeps clicking after it lights often has moisture or a misaligned cap, or a knob switch that is sticking. We pull the caps, clean the ports and watch the flame from low to high.
On a wide top, one spark problem can be mistaken for another, so we test each burner on its own. The rating label gives the exact model and serial, and we read it before ordering any part.

Why does my burner keep clicking after it lights?
A damp or misaligned cap, a sticky switch or a dirty electrode can leave the spark running. We dry and reseat the cap first, then test the switch and spark module.
How is the LSCG366ST different from the LSCG306ST?
The 366 is the 36 in cooktop and the 306 is 30 in. Both share the stacked center burner and large knobs in their listings, so checks are similar but the wider top has more to test.
Do you service older LG gas cooktops?
Yes, we repair units that are no longer made. You get a written price first, and the work carries a 30-day workmanship warranty. Parts for a wide cooktop are matched to the label under the unit.
