Activity

Comment

M10

• 

Compare on another cooking platform and with an induction 
type pan

Check if the pan is appropriate to 
induction cooking or not: use a 
magnet.

M11

• 

Check connection of coil 

• 

Check coil on line break

• 

Coil overheated (brown color change)

M12

• 

Change power circuit board

M13

• 

Check DIP-Switch adjustment on CPU-circuit board

M14

• 

Replace CPU-circuit board

M30

• 

Clear ventilation system

M31

• Clean 

fan

M32

• 

Connect fan directly at 230V

M33

• Change 

rectifi er circuit board

M34

• 

Measure heat-sink temperature sensor resistor
At 25º Celsius (77ºF) resistor will read 20kOhm
At 70º Celsius (158ºF) resistor will read 3,5kOhm

• 

Check short circuit to case

• 

For a test: short-out the sensor with a 20kOhm fi xed resistor

Disconnect temperature sensor

M40

• Switch 

off  unit, cool down and switch on again. Use a pan with 

cold water

Switch off  fi eld!
