Initial abnormality:

CPU (IH) abnormality is not cleared.

IH power voltage abnormality:

The input voltage becomes above 20% (approx.) or below 20% (approx.) of the rated voltage.

IGBT high temperature abnormality:

Overheating of IGBT or short- or open-circuit of IGBT temperature-detecting sensor.

IH circuit abnormality:

Abnormality in IH circuit

IH coil abnormality:

Temperature-detecting sensor in IH circuit is abnormal, or IH coil is open-circuited or wrongly in- stalled.
