Inductor
The inductor is similar to the surface element in a
normal cooking system. When the end user makes
a selection, the signal is sent to the filter board via
the interface. The filter board sends power to the
power board and in turn energizes the inductor.
This creates an electromagnetic field and allows
an electromagnetic transfer of energy from the
inductor to the cooking vessel which generates heat
in the vessel causing it to heat up rapidly.
The inductor has two blue wires that plug into the
power board. Resistance should be approximately
990 Ω when unplugged from the power board. If
resistance is within range, verify voltage from the
«ÜiÀÊL>À`Ê«ÃÌÊ8xÊÀÊ8{°ÊÊvÊÊ«ÜiÀÊÛiÀvÞÊ

>`Ê8ÇÊÊ8ÊivÌÊÀi>ÀÊ>`ÊÀ}ÌÊÀi>À®°ÊvÊÌiÊ`ÕVÌÀÊ
leads are secured and no power out, replace the
power board. If power out and no heat, verify the
cooking vessel is proper (a common refrigerator
magnet will stick to it). If the cooking vessel is
proper, replace the inductor.
Thermal Sensor
The unit is protected by two thermal sensors. The
thermal sensors monitor the temperature of the
cooking zone to ensure the glass does not overheat
and monitors the induction generator temperature
to ensure the electronic components do not
overheat.
The sensor is located under the inductor pad and
has two wires going to the power board. If a
mechanical failure of the sensor occurs, an E9 error
code will appear. To correct, check the sensor
resistance and approximately 990 Ω should be
measured. If no resistance is found replace the
inductor. If resistance is found, and error continues,
replace the inductor. If a thermal failure occurs, an
E2 error code will appear. Allow the cooking zone
to cool down.
NOTE: Replacement parts for items covered in
this section are included in a service kit.
