C3B05 IH temperature sensor
defect
• While the IH heater was on, IH temperature
sensor was disconnected for more than the
predetermined period of time.
• While the IH heater was on, short circuit on
IH temperature sensor continued for more
than the predetermined period of time.
• While the IH heater was on, temperature
change occurred within the predetermined
period of time with over the predetermined
range, and they continued for more than the
predetermined period of time.
• While the IH heater was on, temperature
around the heat radiator stayed high for over
the predetermined period of time.

A
C3B06 IH surge error • While the IH heater was on, IH stopped due
to input voltage which exceeded that of
surge detection voltage, and the surge
detection voltage continued for more than
the predetermined period of time.
 A

halt was detected.
 A
C3B08 IH input voltage error • While the IH heater was on, input power
was at the high voltage detection value or
over for more than the predetermined period
of time.
• While the IH heater was on, input voltage
was at the low power detection value or
under for more than the predetermined
