Cooktop Noise - Sharp SCH2443GB Operation Manual

COOKWARE RECOMMENDATIONS
Follow these recommendations for using cookware:
CORRECT
• Cookware centered correctly on Induction Heater surface.
• Flat pan bottom and straight sides.
• Pan size meets or exceeds the recommended minimum size
for the Induction Heater.
• Pan rests completely on the cooktop surface.
• Pan is properly balanced.
WRONG
• Cookware not centered on Induction Heater surface.
• Curved or warped pan bottoms or sides.
• Pan does not meet the minimum size required for the Cooking
Zone used.
• Pan bottom rests on cooktop trim or does not rest completely
on the cooktop surface.
• Heavy handle tilts pan.
NOTE: ANY one of the incorrect conditions listed may be
detected by the cookware recognition system used in each
cooking zone. If the cookware does not meet correct conditions,
one or more of the Induction Heaters may not heat. (Failure to
heat is indicated by a flashing power level in the digital display
for the affected heater.)
USE THE CORRECT COOKWARE SIZE
The Induction Heaters available on the Induction Cooktop
require a MINIMUM pan size to be used at each location.

BEFORE USING THE COOKTOP
The thick outer line at each Induction Heater is helpful to
determine the MINIMUM cookware size and the MAXIMUM
cookware size. After centering the cookware on the cooktop,
make sure the cookware covers
and does not extend more than
the Induction Heater. The pan must make FULL contact on the
ceramic glass surface without the bottom of the pan touching
the metal cooktop trims.
NOTE: Pan bottom should not exceed
Induction Heater.
If a pan made of the correct material is centered properly on any
of the active Induction Heaters but is TOO SMALL, the power
level will flash in the digital display and the pan will not heat.

COOKTOP NOISE

The induction fields are generated by electronic equipment,
which produces heat at a high power level. A soft-sounding cool-
ing fan runs when the unit is running multiple cooking zones.
Sounds may be produced by different types of cookware, such as:
• Clicking noise may be heard at low power settings. This is
due to the magnetic fields in use and is considered normal
operation.
• The operational noises may be different with various cook-
ware used on the cooktop.
• Light-weight stainless steel pans may make noise or vibrate.
Heavy-weight quality cookware is recommended.
• Cookware with irregular or warped bottoms can vibrate
audibly on the ceramic glass surface at high power settings.
• Cracking noise may be heard if the cookware base is made
of layer of different material.
• Low humming noise is normal at high power settings.
• If multiple cooking zones are used simultaneously at high
power settings with cookware made with a layer of different
material, whistling can occur.
• Loose-fitting handles on cookware can vibrate slightly.
• High-quality cast iron and enamel cookware is less likely to
vibrate or produce noise.
