What Does Error Code HS Mean on a LG Oven?

Hot Surface indicator — surface still hot (not a fault).

HS is a hot-surface indicator, not a fault code. The control monitors residual heat at the cooktop elements or in the oven cavity using temperature sensors, and displays HS while any surface remains above the safe hot-to-touch threshold. It is purely informational and clears itself once the area cools. Unlike a true sensor error such as an open or shorted oven probe, HS reflects normal expected heat and requires no diagnostic action or parts.

Models affected: LG electric and gas ranges with a glass-ceramic or radiant cooktop and a hot-surface warning feature, including models such as LREL6325F and LRGL5825F
What owners report: Owners commonly report seeing HS after finishing baking or using a burner, and it typically disappears on its own within several minutes of cooling. If it stays lit long after everything is cold, it may point to a stuck or failing temperature sensor rather than a genuine hot surface.

Frequently Asked Questions

Can I keep using my LG Oven when error HS appears? +
Usually yes — HS is a low-severity normal notice that rarely stops the oven from working, but clearing the underlying cause prevents it from escalating.
What most commonly causes HS on a LG Oven? +
Across reported LG oven repairs, the most frequent is surface still above the hot-to-touch threshold (100% of cases). Check them in that order before replacing any parts.
HS keeps coming back after a reset — what should I check next? +
A reset only clears the stored HS fault; if it returns, the normal problem is still present. Move on to the physical checks — allow the surface to cool — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix LG Oven error HS? +
A DIY repair typically runs $0–$0 in parts, versus $0–$0 for a professional service call. Expect the work to take about 10–20 minutes.
Which LG Oven models show error HS? +
HS is documented on LG electric and gas ranges with a glass-ceramic or radiant cooktop and a hot-surface warning feature, including models such as LREL6325F and LRGL5825F. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
