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 soundCaused 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 soundMost 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 soundMay 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 soundCaused by the electrical switches.It is normal to hear a clicking noise when operating cooking zones below power level 6.Ticking soundCaused 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 CookwareCookware 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 cyclingThis 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.

Wi-Fi

Trouble connecting appliance and smartphone to Wi-Fi networkThe password for the Wi-Fi network was entered incorrectly.Delete your home Wi-Fi network and begin the connection process again.Mobile data for your smartphone is turned on.Turn off the Mobile data on your smartphone before connecting the appliance.The wireless network name (SSID) is set incorrectly.The wireless network name (SSID) should be a combination of English letters and numbers. (Do not use special characters.)The router frequency is not 2.4 GHz.Only a 2.4 GHz router frequency is supported. Set the wireless router to 2.4 GHz and connect the appliance to the wireless router. To check the router frequency, check with your Internet service provider or the router manufacturer.The appliance and the router are too far apart.If the appliance is too far from the router, the signal may be weak and the connection may not be configured correctly. Move the router closer to the appliance or purchase and install a Wi-Fi repeater.During Wi-Fi setup, the app is requesting a password to connect to the product (on certain phones).Locate the network name which starts with "LG" under Settings > Networks. Note the last part of the network name. If the network name looks like LGE_Appliance_XX-XX-XX, enter lge12345.If the network name looks like LGE_Appliance_XXXX, enter XXXX twice as your password. For example, if the network name appears as LGE_Appliance_8b92, then you would enter 8b928b92 as your password. In this instance, the password is case sensitive and the last 4 characters are unique to your appliance.
