What to Check First
- Does the induction turn off and is [H] displayed while it's operating? Does the highlight turn off and on repeatedly during operation?
- ➔ The overheating prevention function was activated to prevent an accident, and this is a normal function.
- [H] disappears automatically after the induction turns off and the temperature drops below a certain temperature. Cook with low heating power to increase the temperature of the cookware slowly. When using a frying pan, it is recommended that you place and use it on top of the burner, not removing it from the burner if possible. The overheating prevention function is set only for the large burner, so if the burner frequently turns off even though you use it at a lower heating power, use the medium burner.
- ➔ It's normal that the power cycles on and off to adjust the temperature of the cooktop.
- If it is inconvenient for the highlight to turn off and on automatically, set the heating power level to 9. It operates continuously without turning on and off. However, if the inside temperature of the burner reaches 550℃, it still turns on and off on Level 9. If you need higher heating power, use the dual function. When you select the large burner and press the [Dual] button, a red light will light on the indicator lamp and the size of the large burner will increase.
- ※ The On/Off time may differ slightly depending on the model and particular service environments.
