# Cooktop: Hot surface indicator

### What the appliance is actually reporting

This is the indicator that stops people putting a hand on a radiant top that looks cold. LG’s own list says plainly that it is not an error code. It clears itself as the glass cools, usually within twenty minutes of the last zone going off. The only version worth acting on is an H5 that stays lit on a surface that is cold to the touch, which means the sensor rather than the surface.

### The other light combinations that mean this

H5 · HS · H

LG publishes what the indicator lights mean on the washers and dryers that have no numeric display. They are grouped here by what they mean rather than split into near-identical pages, and every pattern the maker names is printed above.

### Where this appears, and why not to clear it

On the indicator lights, on a laundry machine with no numeric display. LG publishes what the patterns mean, and on those models the pattern is the entire diagnosis — it disappears the moment the power is cut. Write it down or photograph the panel before switching anything off, and count a full sequence rather than a single flash: the lights also blink to show cycle status, so treat it as an error only if the machine is misbehaving as well.

### What to do about it

- Wait for the glass to cool and watch the indicator go out.
- If it is genuinely cold and still showing, cut the breaker for thirty seconds.
- Do not cover the cooktop while this is showing.
- Book it only if it persists on a cold top.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 419-0291](tel:+13054190291) and describe what the panel is doing before booking anything.
