On the covered LG range or oven, H5, HS means the cooktop temperature is greater than 150°F — LG's own wording. LG is explicit that this is NOT an error code — it is only an indication that the cooktop is too hot to touch. First, touch nothing on the cooktop and let it cool.
Differential
Likely causes of “LG range or oven code H5, HS”, and how to tell them apart
- 1
The cooktop is still above 150 degrees F
What separates it H5 or HS lights after cooking and goes out as the glass cools
How to confirm Wait and watch whether the indicator goes out by itself
- 2
A hot burner area that cooled slowly
What separates it A large pan or long cook leaves the glass hot
How to confirm Check that no pan is still on the surface
- 3
An indicator that stays on at room temperature
What separates it The glass is cold and the indicator remains
How to confirm Use the breaker sequence LG gives
Before you touch a setting
Record this first — changing settings destroys the evidence
- How long the cooktop has been off
- Whether the glass is cool to the touch
- Whether the indicator goes out when it cools
- The model number

ReversibleTouch nothing on the cooktop and let it cool.
Correct only the documented fault domain
ReversibleNothing to repair while the surface is hot. LG directs that if the surface is at room temperature and the indicator does not turn off, switch the circuit breaker off for 30 seconds.
Leave it alone
ReversibleTouch nothing on the cooktop and let it cool; the indicator only means it is too hot to touch.
Reset if it stays
ReversibleIf the surface is at room temperature and the indicator does not turn off, turn the breaker off, wait 30 seconds and turn it back on.
Wait for the surface to cool
ReversibleThe indicator is a warning that the cooktop is too hot to touch.
Check with the back of your hand held above the glass
ReversibleFeel for radiant heat without touching the surface.
Reset the breaker if it stays on when cold
ReversibleSwitch the circuit breaker off for 30 seconds and back on, as LG directs.
Model-specific
What is true of this model and not of its siblings
- Shown as
- H5 or HS on the cooktop.
- Applies to
- LG ranges and cooktops with a hot surface indicator.
Stop boundary
When this stops being a self-service repair
- !Do not touch the surface while the indicator shows
- !Call LG service if the indicator stays on at room temperature after the breaker sequence
- !Do not touch the cooktop to test it

Common questions
What does H5, HS mean on a LG range or oven?+
the cooktop temperature is greater than 150°F — LG's own wording. LG is explicit that this is NOT an error code — it is only an indication that the cooktop is too hot to touch.
What does HS mean on an LG range?+
The cooktop temperature is greater than 150 degrees F.
Can I touch the surface while HS shows?+
No; treat the surface as hot until the indicator goes out.
Is H5 or HS an error?+
No. LG says it is only an indication that the cooktop is too hot to touch.
How long does it take to go out?+
It goes out once the cooktop falls below about 150 degrees F.
Why is it on after hours?+
A stuck indicator at room temperature is what the breaker sequence is for.
