Power Rating
ATTENTION
The heating area is warmed up by the
hot pan. To avoid injuries (burns) do
not touch the heating area.
Step Action Level Result
1 Place the pan
on the heating
area until water is
boiling
9 (12) Heat, water is
boiling
2 Reduce the power
by turning slowly
the control knob
(12) 9...1 Heat rating
reduces (water
does not boil
anymore), phase
current reduces
continuously
Fan
With this test, the fan observation as well as the degree of
soiling is verified. At the beginning of the test, the induction
cooker should be cold. You need a pan with a bottom
diameter of 28 cm (11”).
Step Action Level Result
1 Place a pan on the
heating area and
fill it up with 1-
Liter or (34 oz) of
water
9 (12) Heat
2 Measure the time
until the fan starts
working
9 (12) The fan should start
working after 6-8
minutes
3 Go on cooking for
about 30 minutes
9 (12) The heating process
may periodically
be interrupted for a
period of 2 seconds.
Unit keeps working.
4 Stop the induction
cooker
0 The fan keeps
working.
Test Of The Components
CAUTION
The power cord must be disconnected
from the power supply.
Rectifier
The rectifier is fixed at the power board with four wires.
Rectifier connections must be unsoldered for correct test
results To begin, you have to measure the forward voltage
between anode – cathode by means of the multimeter
(please use only multimeters with diode check as an
additional function).
The forward voltage for this diode is of about 0.5VDC in
direction A – K, in the opposite direction is “NO” current flow.
If one of the four diodes shows a short circuit or an
interruption, the rectifier is defective and must be
replaced.
