Measure the inductance of the reactor using an LCR meter.
Result:
The inductance MUST be as follows:
Measuring points
Inductance
d‑e
104~116 µH
Is the inductance measurement
correct?
Action
Yes
Return to the troubleshooting of the
specific error and continue with the
next step.
No
Replace the reactor, see
3.18.2 Repair procedures
As the reactors are part of the main PCB, replace the complete main PCB. See
