The surface cooking area will glow red when an element is on.
Some parts of the surface cooking area may not glow red when
an element is on. This is normal operation. The burner will cycle
on and off to maintain the selected heat level. It will also randomly
cycle off and back on again, even while on High, to keep the
cooktop from extreme temperatures.
It is normal for the surface of light colored ceramic glass to appear
to change color when surface cooking areas are hot. As the glass
cools, it will return to its original color.
Cleaning off the cooktop before and after each use will help keep
it free from stains and provide the most even heating. On cooktops
with light colored ceramic glass, soils and stains may be more
visible, and may require more cleaning and attention. Cooktop
cleaner and a cooktop scraper are recommended. For more
information, see "General Cleaning" section.
Avoid storing jars or cans above the cooktop. Dropping
n
a heavy or hard object onto the cooktop could crack the
cooktop.
To avoid damage to the cooktop, do not leave a hot lid on
n
the cooktop. As the cooktop cools, air can become trapped
between the lid and the cooktop, and the ceramic glass could
break when the lid is removed.
For foods containing sugar in any form, clean up all spills and
n
soils as soon as possible. Allow the cooktop to cool down
slightly. Then, while wearing oven mitts, remove the spills
using a scraper while the surface is still warm. If sugary spills
are allowed to cool down, they can adhere to the cooktop and
can cause pitting and permanent marks.
To avoid scratches, do not slide cookware or bakeware across
n
the cooktop. Aluminum or copper bottoms and rough finishes
on cookware or bakeware could leave scratches or marks on
the cooktop.
Do not cook popcorn in prepackaged aluminum containers on
n
the cooktop. They could leave aluminum marks that cannot be
removed completely.
To avoid damage to the cooktop, do not allow objects that
n
could melt, such as plastic or aluminum foil, to touch any part
of the entire cooktop.
To avoid damage to the cooktop, do not use the cooktop as a
n
cutting board.
Use cookware about the same size as the surface cooking
n
area. Cookware should not extend more than 1/2" (1.3 cm)
outside the area.

Use flat-bottomed cookware for best heat conduction and
n
energy efficiency. Cookware with rounded, warped, ribbed or
dented bottoms could cause uneven heating and poor cooking
results.
Determine flatness by placing the straight edge of a ruler
n
across the bottom of the cookware. While you rotate the
ruler, no space or light should be visible between it and the
cookware.
Cookware designed with slightly indented bottoms or small
n
expansion channels can be used.
Make sure the bottoms of pots and pans are clean and dry
n
before using them. Residue and water can leave deposits
when heated.
To avoid damage to the cooktop, do not cook foods directly
n
on the cooktop.
