Top Sensor Open Error (Sensor-Top)
It occurs due to a defective sensor, misplaced wires, a defective PCB and
when A/D value that MICOM senses rises over 252.
Also, it may occur when the ambient temperature falls under -10
˚C
.
Top Sensor Short Error (Sensor-Top)
It occurs due to a defective sensor, misplaced wires, a defective PCB and
when A/D value that MICOM senses falls under 10.
IGBT Sensor Open Error (Assy-Inverter Module)
It occurs due to a defective sensor, misplaced wires, a defective PCB and
when A/D value that MICOM senses rises over 239.
Also, it may occur when the ambient temperature falls under -10˚C.
IGBT Sensor Short Error (Assy-Inverter Module)
It occurs due to a defective sensor, misplaced wires, a defective PCB and
when A/D value that MICOM senses falls under 10.

Touch Button Short
Error
It occurs when the control panel’s sensor field is shorted
more than 10 seconds .
ex: No .1 Place a damp cloth on the control panel .
No.2 Liquid boils over and lands on the control panel.
No .3 More than one key is pressed more than
10 seconds .
No .4 Defective Assy-Touch PCB
Low Voltage Error
It occurs when the DC 12V is dropped under 9V .
It may occurs due to defects of PCB or wiring .
Over Temperature Error It occurs when the temperature of the Top Sensor rises
very highly .
(Estimated temperature of ceramic glass’s surface is
more than 250˚C.)
ex: Place a empty cookware on the burner and operate the
hob .
Pan Detection Error
It occurs when the cookware is unsuitable or too small or
no cookware has been placed on the cooking zone .
If the suitable cookware is placed again, the hob will oper-
ate normally .
