LG induction cooktop displays HE and may shut down the affected zone.

Safety first: Turn off the cooktop and allow it to cool. Disconnect power before removing any panels.

• Clear vents: Ensure that the cooktop's intake and exhaust vents are not blocked by cookware, insulation, or cabinetry.
• Check fan operation: When the cooktop is in use, you should hear the internal cooling fan. If not, the fan may have failed.
• Inspect internal components: With power OFF, remove the cooktop from the counter (if required) and remove the bottom cover. Check for dust buildup around the coils and fan; clean carefully.
• Replace faulty parts: If the fan is seized or noisy, replace the cooling fan. If HE persists, the temperature sensor on the affected coil or the power board may be defective and require replacement.
