LG Range H5 Code — Cooktop Surface Hot
What this means
The H5 indicator appears when the cooktop surface temperature remains above 150 degrees F after a burner has been turned off. This is a safety warning, not a malfunction. It alerts users that the surface is still hot enough to cause burns. The indicator will disappear once the surface cools below 150 degrees F.
Step-by-step fix
2 stepsWait for cooling
Allow the cooktop surface to cool naturally. Do not place anything on the hot surface. The H5 indicator will disappear automatically once the surface cools below 150 degrees F.
This is a normal safety feature. Glass cooktops retain heat longer than coil or gas burners.
If H5 persists after cooling
If the H5 indicator remains after the surface has clearly cooled (touch cautiously at the edges first), reset the circuit breaker for 30 seconds.
When to call a professional
If the H5 indicator persists long after the surface has cooled, the surface temperature sensor may be faulty.
