Transistor module (IGBT)
G
E
C
The IGBT (
Insulated Gate Bipolar Transistor
) is fixed onto the
power print (board) with three solder connections.
The IGBT Transistor has as a supplementary protection an
integrated recovery diode. To begin, measure the on-state
voltage of this diode. The forward voltage of this diode is
approximately
0.5VDC.
If the recovery diode shows a short circuit or an
interruption, the IGBT transistor is defective and must be
replaced.
CU (RTCS) Sensors
CU Sensor 1 (Center)
4 – 5.5 Ohms
CU Sensor 2 (Outer)
4 – 5.5 Ohms
The two CU sensors are mounted directly on top of the coil
for base-line, (counter top) cookers. Both the center and
outer sensors, will measure approximately 4 - 5.5 Ohms.
Potentiometer
The potentiometer is mounted onto the main power switch.
On setting “0” the reading will be 0 - Ohms and on the
maximum level, the resistor will read 10kOhm (10,000 Ohms).
Resistor is proportional (linear) to swing angle. (see following
photo for measurement points).
