Introduction to Induction Cooking
How Induction Cooking Works
Induction cooking uses high frequency (20-50 K hz)
magnetic energy to heat a ferrous metal pan when
it is placed over the induction coil. The induction
fields have no affect on non magnetic surfaces
such as paper, plastic, or non ferrous metals like
aluminum, or copper. Thermal sensors under the
glass surface communicate with microprocessor
controls for pan sensing and turn-down.
Part one: Coil produces electromagnetic energy
The first component needed is an induction coil or
element. The induction coil generates the magnetic
field needed for induction cooking.
Part two: Pan uses the energy to produce heat
The second component is the ferromagnetic cooking
pan with a bottom constructed of material that will
attract a magnet. If a magnet will not stick to the
bottom of the pan, it can not be used for induction
cooking.
When the proper type of pan is placed over an
energized induction coil, a field of magnetic waves
will cause the bottom of the pan to heat.
Induction cooking is very efficient. The energy
Glass Cooktop Surface Induction Coil
Testing Bottom of Pan with Magnet
Water
Glass Cooktop Surface Induction Coil
Pan with Bottom of
Magnetic Material
created by the induction coil is applied to only the
bottom of the pan.
The contents of the pan are therefore heated more
quickly than they would be if heated by a gas
flame or a traditional radient heating element.
By heating only the bottom of the pan, the
surrounding surface remains cooler than with
traditional cooktops.
Features:
Easy cleanability• ―Cooktop cleaning is easier
since spills and splatters do not burn on the
cooktop, which is about 500°F vs 1200°F for
radiant.
Control and responsiveness equal to gas• ―
This induction cooktop give you instant control
of the amount of heat added to the cookware.
Fast and Powerful• ―providing an incredibly
fast boil time. 3700 w, 8.5 min. to boil vs 12 to
14 min. for radiant and 14 to 16 min. for gas
(18k BTU).
Efficient performance• ―Induction technology
heats only the pan and its contents, not the
kitchen. Efficiency ratings are: Induction 83%,
Radiant 72%, and gas 38%.
Induction Fields
Note: There are no health risks associated with the use of this cooktop. The RF field from an induction
element dies away to almost nothing at a distance of about one foot (30 centimeters). You will not receive
even trivial radiation from an induction cooktop unless you spend a long time well within one foot of an
operating element.

Installation
WARNING: Before beginning the installation,
switch power off at the service panel and lock the
service disconnecting means. When the service
disconnecting means cannot be locked, securely
fasten a warning tag to the service panel.
Note: The complete installation instructions are
inclosed with the Use and Care Manual. Carefully
read and follow these instructions.
The following minimum clearance dimensions must
be maintained.
Power Supply
The cooktop must be connected to a supply circuit
of the proper voltage and frequency as specified
on the rating plate. Wire size must conform to the
National Electrical Code or the prevailing local code.
The rating plate is located on the bottom of the
burner box.
Wiring
Built-in power leads are UL-approved for connection
to larger gauge household wiring. The insulation of
these leads is rated at temperatures much higher
than the temperature rating of household wiring.
The current-carrying capacity of a conductor is
governed by the temperature rating of the insulation
around the wire rather than the wire gauge alone.
WARNING: Improper connection of aluminum house
wiring to these copper leads can result in a serious
problem. Use only connectors designed for joining
copper to aluminum and follow the manufacturer's
recommended procedure closely.
Ceramic Glass Cooktop
If the glass is damaged, it may be replaced as a
separate part. The touch board and electronics are
separate parts.

How induction cooking works. ge.com
The elements beneath the cooking
surface produce a magnetic field that
causes the electrons in the ferrous
metal pan to vibrate and produce
heat.
The cooking surface itself does not
heat. Heat is produced in the cooking
pan, and cannot be generated until a
pan is placed on the cooking surface.
When the element is activated, the pan
begins to heat immediately and in turn
heats the contents of the pan.
Magnetic induction cooking requires
the use of cookware made of ferrous
metals—metals to which magnets will
stick, such as iron or steel.
Use pans that fit the element size.
The pan must be large enough for the
safety sensor to activate an element.
The cooktop will not start if a very
small steel or iron utensil (less than
the minimum size across the bottom) is
placed on the cooking surface when
the unit is turned on—items such as
steel spatulas, cooking spoons, knives
and other small utensils.
Min. Size
Each cooking element requires a MINIMUM pan
size. If the pan is properly centered, and of the
correct material, but is too small for the cooking
element, the element cannot be activated. The
display will flash “F” along with the power level
selected.
Cookware larger than the element ring may be
used; however, heat will only occur above the
element.
For best results, the cookware must make FULL
contact with the glass surface.
Do not allow the bottom of the pan or cookware to
touch the surrounding metal cooktop trim or to
overlap the cooktop controls.
For best performance, match the pan size to the
element size. Using a smaller pot on a larger burner
will generate less power at any given setting.

Choosing the correct cookware to use.
Cookware not centered on cooking
element surface.
Cookware must fully contact the surface of the
cooking element.
Use flat-bottomed pans sized to fit the cooking
element and also to the amount of food being
prepared.
CAUTION:
■The cooking elements may appear to be cool while
turned ON and after they have been turned OFF.
The glass surface may be HOT from residual heat
transferred from the cookware and burns may occur.
■DO NOT TOUCH HOT COOKWARE or PANS directly
with hands. Always use mitts or pot holders to
protect hands from burns.
■DO NOT SLIDE cookware across the cooktop
surface. Doing so may permanently damage the
appearance of the ceramic cooktop.
Curved or warped pan bottoms
or sides.
Pan does not meet the minimum
size required for the cooking
element used.
Cookware centered correctly
on cooking element surface.
Flat pan bottom.
Pan size meets or exceeds the
recommended minimum size
for the cooking element used.
INCORRECT CORRECT
Pan bottom rests on cooktop trim
or does not rest completely on the
cooktop surface.
Heavy handle tilts pan.
Pan bottom rests completely on the
cooktop surface.
Pan is properly balanced.

For Best Results
■Do not place wet pans or lids on the
cooking surface or induction rings.
■Do not place wet fingers on the glass
cooktop. Wipe up spills on the controls
with dry hands.
■Do not use woks with support rings. This
type of wok will not heat on an induction
element.
■Use only a flat-bottomed wok, available
from many cookware manufacturers.
The bottom of the wok should match the
diameter of the induction ring to insure
proper contact.
■Some special cooking procedures
require specific cookware such as
pressure cookers, deep-fat fryers, etc.
Cookware with flat bottoms that match
the size of the surface element being
used will produce the best results.
Do not place wet pans
on the glass cooktop.
Do not use woks with support
rings on the glass cooktop.
Use flat-bottomed woks
on the glass cooktop.
Use quality cookware with heavier
bottoms for better heat distribution
and even cooking results. Choose
cookware made of magnetic stainless
steel, enamel coated cast iron,
enameled steel and combinations
of these materials.
Some cookware is specifically
identified by the manufacturer for use
with induction cooktops. Use a magnet
to test if the cookware will work.
Flat-bottomed pans give best results.
Pans with rims or slight ridges can be
used.
Round pans give best results. Pans
with warped or curved bottoms will
not heat evenly.
For wok cooking, use a flat-bottomed
wok. Do not use a wok with a support
ring.
Cookware “noise”
Slight sounds may be produced by
different types of cookware. Heavier
pans such as enameled cast iron
produce less noise than a lighter
weight multi-ply stainless steel pan.
The size of the pan, and the amount
of contents, can also contribute to
the sound level.
When using adjacent elements that are
set at certain power level settings,
magnetic fields may interact and
produce a low whistle or intermitted
"hum". These noises can be reduced or
eliminated by lowering or raising the
power level settings of one or both of
the elements. Pans that completely
cover the element ring will produce less
noise.
A low “humming” noise is normal
particularly on high settings.
Use a flat-bottomed wok.
Use a griddle.
Use flat-bottomed pans.
Suitable Cookware

Setting the controls.
Touch the pad lightly with the flat part
of your fingertip. Touch the center of the
pad to ensure the cooktop response.
A "beep" sound can be heard with each
touch to any pad.
Using the Touch Control.
Operating the Cooking Elements
Each of the cooking elements have
separate ON/OFF pads and LED display.
Be sure to use cookware that meets the
minimum pan size requirements.
To turn on a cooking element:
Place a pan with food onto the
induction element. The pan size
should match the indicator ring.
Touch the ON/OFF pad. “5” will flash
in the display.
Touch the (+) or (-) pad to select power
level and to activate the induction
element. A sound will beep. The (+) or
(-) pad must be pressed within 10
seconds to activate the element.
NOTE: You can also touch and hold the
pad to scroll quickly to the desired setting.
The induction circuit detects the pan and
allows the element to be activated. Both
the element ON indicator light and the
cooktop HOT SURFACE light will illuminate.
If no power level is selected within 10
seconds, the zone will be deactivated.
To turn the control to OFF, touch the
ON/OFF pad. The induction element will be
turned off and the display will be blank.
With an element control ON:
If a pan is removed or moved to off-center
from the cooking ring, the control will flash
“F” along with the power setting. After 30
seconds, the element will be deactivated
and displays will turn off.
If the pan is placed back on the zone
within 30 seconds, the flashing will stop
and cooking will resume.
Power Level Settings
The cooktop offers 19 power levels,
including a Boost setting. Power levels
range from “L” to 9 in precise half-step
increments. For example: 1, 1-1/2, 2,
2-1/2 and up to power level 9.
Power Level “L”, the lowest setting, is
recommended for “Keep Warm.”
The power level increases one-half level
with each touch.
Power level 9 is the highest normal
power setting.
1/2
The power level with a fraction
indicates the additional half-step
setting.
Flashing “F” in the Display
If a pan is removed or moved off-center
from the cooking ring during the
cooking process, the control will flash
“F” along with the power setting. The
flashing "F" indicates that the pan is no
longer detected. After 30 seconds, the
element will be deactivated and the
display will turn off.
If the pan is returned to the surface
element within 30 seconds, the flashing
“F” will disappear and cooking will
resume.
(Continued next page)

– 13 –
Boost is the highest power level, designed
for large quantity rapid cooking and
boiling. Boost will operate for a maximum
of 10 minutes. After 10 minutes, it will
automatically revert to power level 9.
Boost may be repeated after the initial
10 minute cycle.
CAUTION: Do not leave a pot unattended
while in the Boost Mode.
To start the Boost power setting:
Place a pan matching the size of the
induction element over the selected
indicator ring.
Touch the ON/OFF pad. “5” will flash
in the display.
Touch and hold the (+) pad until the
display reads “H.”
NOTE: If the pan is removed, the display
will flash “F” alternating to “H”. After 30
seconds, the elements will turn off
automatically.
Sounds you may hear:
You may hear a slight “buzz” sound when
cooking with the Boost or high mode. This
is normal. The sound depends on the type
of pot being used. Some pots will “buzz”
louder depending on the material. A “buzz”
sound may be heard if the pan contents
are cold. As the pan heats, the sound will
decrease. If the power level is reduced, the
sound level will go down.

Power Sharing
Four burner cooktops are divided into two separate
heating zones. The right and left side cooking zones
are powered by separate and independent induction
generators. One generator controls 2 elements, or two
cooking zones within a heating section share the power
of one generator.
Five burner cooktops are divided into 3 zones. The
right and left side have separate cooking zones and the
large center element is another separate cooking zone.
Power Sharing is activated when both elements in the
same cooking zone are activated and one element is
set for Boost (H). The element that is not set for Boost
will change to a lower power level. This is called
Power Sharing. When Boost operation is complete
(10 minutes), the other element may be reset to any
power level. Both elements can operate simultaneously
at normal power level settings of “L” to 9.
4 burner cooktops with right and left side (2) induction generators.
5 burner cooktops with right, left and center (3) induction generators.
“H” indicates that the Boost power
level has been selected for rapid
cooking and boiling.
IMPORTANT NOTE FOR FOUR BURNER MODELS:
The elements on the right side share one generator.
Both elements can operate at any non-Boost (level L
to 9) power level at the same time. If the large front
element is set for "H" or Boost, the smaller element
at the right rear will be deactivated or turned off
automatically. The smaller right rear element can be
activated and set for any power level after the Boost
operation of the larger element is completed (10
minutes).

Place a pan with food onto the
induction element. The pan size
should match the indicator ring.
Touch the ON/OFF pad. “5” will flash
in the display.
Touch the (-) pad until the display
reads “L.” A sound will beep.
Do not use plastic wrap to cover food.
Plastic may melt onto the surface and be
very difficult to remove.
Use only cookware recommended for
this cooktop.
The Low setting will keep hot, cooked food
at serving temperature. Always start with
hot food. Do not use to heat cold food.
Placing uncooked or cold food on surface
element set for Low could result in food-
borne illness.
For best results, all food set for Low should
be covered with a lid or aluminum foil.
Pastries or breads should be vented to
allow moisture to escape.
Always use pot holders or oven mitts when
removing food from the element set for
Low as cookware and plates will be hot.
Using the "L" Low Setting
CAUTION: Do not warm
food on the “L” power level
for more than two hours.
NOTE: Use the kitchen timer to measure
cooking time or as a reminder. The kitchen
timer does not control the cooking
elements.
Touch the Timer ON/OFF pad.
Touch the (+) or (-) pad to choose the
desired number of minutes. When the
(+) or (-) pad is held for several
seconds, the timer will increase or
decrease at a faster rate. The timer will
automatically start to count down the
minutes you have selected within 5
seconds of the last entry. The display
will show the minutes and a “ .“
will flash.
The timer displays minutes remaining
until it reaches one minute. At one
minute, the timer will beep and start
counting down seconds.
With one minute remaining, the timer
will beep every 10 seconds. When all
time has counted down, the timer will
signal a long beep and the display will
become blank.
Touch the ON/OFF pad to turn the timer
off at any time. Touch (+) or (-) to add or
subtract to the set time.
Using the Kitchen Timer
A HOT SURFACE indicator light (one for each
cooking element) will glow immediately
when any element is activated. The
indicator light(s) glow when the glass
surface is hot, and will remain on until the
surface has cooled to a temperature that is
safe to touch.

Using the surface elements. ge.com
Error alerts indicate a temporary problem
that may be corrected by the user.
Clear Keypad—If the display flashes “E”
alternating to “c”, the keypad is sensing
continuous activation of one or more
keypads. Clean or clear any obstructions
on the keypad area. Obstructions may be
water, food spills, a utensil or other objects.
To resume cooking, touch the ON/OFF pad,
then select the power level.
Over Temperature—If the display flashes
“E” alternating to “o”, the cooktop sensor
indicates that the induction element or
electronics have overheated.
Overheating of the element is caused by
placing an empty pan on the element and
selecting a high power level. The element
sensor detects very high temperatures
(above normal cooking temperatures),
turns off the power and displays the error.
A second potential cause of this error is
a lack of cooling air to the bottom of the
cooktop, which can cause overheating
of the electronics. If this situation occurs,
make sure the air inlet below the cooktop
is unobstructed.
Touch the ON/OFF pad and allow the
cooktop to cool for 30 to 45 minutes before
operation can begin again.
If either of these conditions persist,
call for service.
IMPORTANT: If the “E” flashes alone,
without alternating to a “c” or “o”, a
hardware error has occurred. Call for
service.
Error Alerts (Flashing “E”/”c” and “E” “o”)
IMPORTANT: As a convenience, you can
lock the entire cooktop at any time when it
is not in use or before cleaning. Locking the
cooktop will prevent surface elements from
being turned on accidentally.
To lock the cooktop:
Touch and hold the CONTROL LOCK pad
for 5 seconds.
A two-beep signal will sound, and the
CONTROL LOCK light will glow, indicating
that the cooktop is locked.
If the cooktop is locked while a surface
element is in use, it will automatically
turn off.
The CONTROL LOCK does not affect the
timer. If Control Lock is set while the timer is
counting down, it will continue to operate.
To unlock the cooktop:
Touch and hold the CONTROL LOCK pad
again for 5 seconds. A two-beep signal will
