What HS
actually means.
HS lights when the stovetop is above 150 degrees F. LG says outright that it is not an error code, just a warning that the surface is hot.

What to do when HS shows on the stoveKind of codeMode, not a failure
Something the stove was switched into, often by accident, rather than something that broke: a control lock pressed while wiping the panel, a Sabbath setting, a showroom demo mode that lights the display and heats nothing, a reminder that a spot on the stovetop is still hot. No part is worn out, and the stove's own keys put it right.
Usually leads toNo repair
Keep hands, towels and children away from the stovetop until HS goes out.

The burners on an electric, glass or induction stovetop stay cold or warm up only a little, sometimes all of them and sometimes two on one side, while the oven below may still work.

Before you book,
in this order.
Each step comes from LG's own guidance for HS on its stoves. Follow it to the end: the last card says whether this is a visit.
Keep hands, towels and children away from the stovetop until HS goes out.
Wait for the surface to cool; HS turns off on its own.
If HS stays lit on a top that is cool to the touch, switch the breaker off for 30 seconds and back on, then book a visit if it stays.
Cleared?
The stove is working again and no part was needed. If the same letters come back while a burner or the oven is on, or the stove switches itself off again in the middle of dinner, book it as a new problem.
What not to do
HS is not a warning that something is broken. It becomes a service matter only if it stays on over a cold stovetop.

Induction stove

Still showing HS?
Book with the code written exactly as the stove shows it, the full model number, and whether you notice any smell of gas or hot wiring — when there is a code, that is where the diagnosis starts.
