Minimum cookware size
Use cookware with a bottom surface diameter of 5 13/16" (147 mm) or greater.
Use the recommended cookware. See Induction Cookware.
A fan sound can be heard.
Cooktop inner temperature is high.
This is normal.
The cooling fan will run when any element is turned on. With heavy use the fan may continue to run after the controls are turned off until the cooktop has cooled.
Noises are heard during cooking. The following noises are normal.
Humming/buzzing sound
Caused by the magnetic field transmitting power to the cookware. It is most noticeable at high power settings and becomes quieter if the power is reduced.
Whistling sound
Most noticeable with lighter weight cookware or when cookware is empty.
Under certain conditions, your cookware may produce a high-pitched whistling noise when two elements are in use at the same time. The power levels at which this occurs may vary depending on the kind of cookware being used. Change the power level to eliminate the noise or reduce its volume.
Cracking sound
May occur when using composite cookware as the different materials resonate and heat at different rates. This will not damage or impair the performance of the cookware.
Clicking sound
Caused by the electrical switches.
It is normal to hear a clicking noise when operating cooking zones below power level 6.
Ticking sound
Caused by the cookware detection.
The Boost function has been deactivated or cannot be activated.
To prevent damage to the product, the cooking zones are separated into two groups, and you can only use the Boost function on one cooking zone in each group at once. As shown in the Operation section under "Using the Cook Modes," you can use Boost on a cooking zone in group 1 and a cooking zone in group 2 at the same time. If the power range is exceeded by selecting the Boost function, a power management function automatically reduces the heat setting of the cooking zone. If you try to use Boost on two cooking zones in the same group, the selected cooking zone displays a flashing b and G and the power level is automatically set to 9 rather than Boost.
For safety, after 6 minutes the Boost setting will automatically revert to either power level 9 or the previously set power level.
The cookware cannot be detected automatically.
Cookware is not compatible with induction cooktop.
Use only cookware that is compatible with the induction cooktop. For details of compatible cookware, see Induction Cookware
Cookware has been damaged.
Cookware is overheated.
Never use the Boost mode to preheat empty cookware or to heat oil, butter or lard.
Use the Boost function to boil water or heat up large quantities of food quickly.
Output power is different when the same type of cooking zone is used.
Cooktop is overheated.
The power level displayed may be different from the actual power level at the high end of the temperature range. To prevent the cooktop from overheating, the power level is controlled automatically.
Power cycling
This is normal.
During use, the heating element cycles on/off to control the output power.
The Control Panel does not work properly.
Hot cookware is placed on top of the control panel.
To prevent malfunction, do not place the hot cookware on top of the control panel.
Error code FO, F1, F2, F3, F4, F5, F6, F7, F8, F9, FF, Fn, FP, FC, FD, FE appears on the display.
Electronic control has detected a fault condition. Turn the power off and on again to turn off the error code.
If the issue recurs, call for service.
Error code does not appear on the display.
Turn off the cooktop and restart it.
If the problem continues, turn the circuit breaker off for 60 seconds and turn it back on. If the problem is not fixed, contact a local LG service center or Customer Information Center.
Timer does not turn off the cooking zone.
This is normal.
The kitchen timer/cooking timer acts as a simple timer and does not turn off the cooking zone.
The hot surface indicator stays on after the cooking zones are turned off.
This is normal.
After you turn off the cooking zones, the indicator remains on until the ceramic glass surface cools down.
If the temperature near the product is high, it may take longer for the ceramic glass surface to cool down.
