LG Cooktop Error Code H

The H indicator on an LG cooktop is a normal status message, not a fault code. It appears after initial power-up, after a power outage, or when a cooking surface is still retaining heat from recent use. It is a safety notification designed to warn users that the glass surface may still be too hot to touch.

If H is showing because of residual heat, avoid touching the surface until the message clears, as the glass may still be dangerously hot. If the message appeared due to a power-up or outage and the surface is not hot, press ON/OFF once and the cooktop can be used normally. The H indicator is a safety feature, not a sign of a hazardous malfunction.

No, the H indicator does not signal a component failure and does not require any repair or replacement parts. It is a built-in status and safety message. There should be no cost associated with this message appearing under normal post-cooking or post-outage conditions. If the H indicator appears persistently and the surface is not hot and no outage occurred, it may be worth contacting a technician, though repair costs in that scenario would vary depending on diagnosis.

Press the ON/OFF key one time and then operate the cooktop as you normally would. If the H is displaying because the surface is still hot, it will clear automatically once the glass cools to a safe temperature. No reset procedure or service call is required.

Yes, pressing the ON/OFF key once will clear the H display in most cases involving startup or post-outage initialization. However, if the H is present because the surface element is genuinely still hot, the indicator will return until the surface temperature drops to a safe level. Resetting does not bypass the thermal safety function.
