Cooktop Noise - Sharp SDH3042DB Operation Manual

BEFORE USING THE COOKTOP
COOKWARE RECOMMENDATIONS
Be sure to follow the following recommendations for using
cookware:
INCORRECT
• Cookware not centered on Cooking Zone 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.
CORRECT
• Cookware centered correctly on Cooking Zone surface.
• Flat pan bottom & straight sides.
• Pan size meets or exceeds the recommended minimum size
for the Cooking Zone.
• Pan rests completely on the cooktop surface.
• Pan is properly balanced.
NOTE: ANY one of the incorrect conditions listed may be
detected by the sensors located below the ceramic cooktop
surface. If the cookware does not meet any of these conditions,
one or more of the Cooking Zones will not heat indicated by a
flashing power level in the digital display for that affected zone.
Correct the problems before attempting to reactivate the cooktop.
USE THE CORRECT COOKWARE SIZE
The Cooking Zones available on the Induction Cooktop require
a MINIMUM pan size to be used at each location.

Cooking zone outer line
COOKWARE SIZE GUIDE
The thick outer line at each Cooking Zone is helpful to determine
the pan MINIMUM size as well as the pan MAXIMUM size.
After centering the cookware on the cooktop, make sure the
cookware does cover 1/2" inside of the thick outer line and does
not extend more than 1/2" beyond the thicker line on the Cooking
Zone. The pan must make FULL contact on the glass surface
without the bottom of the pan touching the metal cooktop trims.
NOTE: Pan bottom should not exceed 1/2" (13 mm) from outer
Cooking Zone (Induction).
If a pan made of the correct material is centered properly on any
of the active Cooking Zones but is TOO SMALL, the power level
will flash in the in the digital display and the pan will not heat.

COOKTOP NOISE

The induction fields are generated by electronics equipment,
which produce heat at a high power level. A soft-sounding cool-
ing fan runs when the unit is running multiple cooking zones.
Slight sounds may be produced by different types of cookware.
Some of the possible causes include:
• Clicking noise may be heard at low power settings. This is
due to the magnetic fields in use, which is considered normal
operation.
• The operational noises may be different with various cook-
ware used on the cooktop.
• Heavier pans such as enameled cast iron produce less
noise than a lighter weight stainless steel pan; Light weight
cookware may also vibrate. Heavy weight quality cookware
is recommended.
• Cookware with irregular or warped bottoms can vibrate
audibly on the ceramic glass surface, though again typically
only at high power settings.
• A "cracking" noise may be heard if the cookware base is
made of layer of different material.
• A low "humming" noise occurs when cooking, which is
normal particularly at high power settings.
• Whistling can occur if both cooking zones are being used
at the same time at the high settings, and the cookware has
bases made of layer of different material.
• Loose-fitting handles on cookware, typically when riveted
on, can vibrate slightly.
• High quality cookware of solid cast iron including enamel-
ware will lower the noise.
