Warranty Information
This limited warranty covers parts and labor for one year from the date of original purchase.
How Induction Cooking Works
An induction coil beneath the ceramic glass cooking surface generates magnetic fields, which act directly on the base of the pots and pans.
Instead of heating the ceramic glass, this method heats the base of the pan immediately, saving time and energy. Since the heat required for cooking is generated directly in the base of the pan, the cooking zone itself warms up only slightly. The cooktop does become hot when heat is transferred from the cookware.
Cookware
The base material of the cookware must be magnetic for the cooking elements to activate. Use a magnet to check if the cookware base material is suitable.
Troubleshooting and error codes
| Symptoms | Possible Causes and Solutions |
| Cooktop does not operate. | The control buttons may be locked. See "Control Lock" section to disable the control lock function. |
| The circuit breaker has tripped or the fuse is blown. Reset the circuit breaker. | |
| Power outage. Check the house lights to confirm if there is a power outage. | |
| Installation wiring is not complete. Contact the installer or retailer. | |
| Cooktop does not heat. | The selected cooking zone is incorrect. Ensure you activate the correct control for the cooking zone used. |
| The cooktop is not powered. See "Cooktop does not operate" above. | |
| Elements turn off during cooking. | The internal temperature of the cooktop is too high. Ensure the cooktop was installed according to the installation instructions. |
| Elements are not hot enough. | The control panel may not be set correctly. Check the power level. |
| Cooking accessories are not compatible with induction. Use induction-compatible accessories. | |
| Cooking accessories may not be flat or the correct size. Use accessories with a flat bottom. Minimum pan size for induction is 5 13/16" (147 mm) or larger. For the flex zone, minimum size is 4 3/4" x 10 5/8" (120 mm x 270 mm). For dual zones, use a pan with a bottom diameter of 11" or larger. Refer to the "Induction Cookware Accessories" section. | |
| The fan may run. | The internal temperature of the cooktop is high. This is normal. The cooling fan runs when an element is on. It may continue to run after controls are turned off until the cooktop cools down. |
| Noises during cooking. The following noises are normal. | Buzzing: Caused by the magnetic field transmitting energy to the cookware. More noticeable at high power settings. |
| Whistling: More noticeable with light or empty cookware. Can occur when two elements are used simultaneously. Adjust power level to reduce or eliminate noise. | |
| Cracking: May occur with composite cookware as materials resonate and heat at different speeds. This is normal and will not damage the cookware. | |
| Clicking: Caused by electrical switches. Normal below power level 6. | |
| The "Boost" function is deactivated or cannot be activated. | For product safety, cooking zones are separated into two groups. Boost can only be used on one zone per group at a time. If the power range is exceeded, power management automatically reduces heat. If Boost is attempted on two zones in the same group, the selected zone will display 'b' and '9' flashing, and power will be set to 9. Boost mode automatically reverts to power level 9 after six minutes. |
| The cookware cannot be detected automatically. | The cookware is not compatible with induction. Use induction-compatible cookware. |
| The cookware has been damaged. | The cookware has overheated. Never use Boost mode to preheat empty cookware or to heat oil, butter, or lard. Use Boost to boil water or quickly heat large quantities of food. |
| Output power differs when the same cooking zone is used. | The cooktop is overheating. The displayed power level may differ from the actual power level at the high end of the temperature range. Power level is automatically controlled to prevent overheating. This is normal. The heating element cycles on and off to control output power. |
