6.7.4.
Component test procedure for magnetron and H.V.inverter
Caution: First, remove wiring of the component to be checked to make it a stand-alone condition.
6.7.4.1.
How to check an H.V.inverter
Mainly use failure diagnosis of F97/FE7/F98/FE8
Caution:
Polarity of a tester is shown below.
Use the tester as shown for measurement.
Otherwise, misjudgment may occur.
