3 Testing Power Component

1. When alarm messages and disabled zones exist ("E“ in cooking phase display), please make

a note of the power component which is affected.

2. (7) Check whether the lead from the filter board is connected, also check the bus lines (6)

µprocessors filter to power component.

3. If (8) IGBT has become shorted, this normally means that the IGBT housing is damaged.

Replace power component

4. (8) Measure resistance at the IGBTs

Pin1-Pin2 or Pin2-Pin3 >50kOhm Æ Okay

<50Ohm Æ power component defect & replace

Only replace the affected power component and (9) insert 20A fuse, completely separate the

fuse strip conductor.

S12 = right power component

S11 = left power component

5. By a short-circuit and destroyed power component, it is imperative that the coil lines be

inspected for signs of damage.

6. Also replace the filterboard should the replacement of the power component not succeed.
