38 TROUBLESHOOTING
Noises are heard
during cooking. The
following noises are
normal.
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 burners 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, if one of the right-side elements is turned on when
the center dual element is using the Boost setting, the power setting of the center dual
element is automatically reduced to power level 9.
• To maintain the Boost setting on the center dual element, use any of the left side elements
instead.
• For safety, after 6 minutes the Boost setting will automatically revert to either power level
9 or the previously set power level.
