Electrolux In General - Component Testing: Magnetron, HV Capacitor, HV Transformer

- disconnect the mains plug
- ensure that the capacitor has
been discharged!
- separate the magnetron
- measure the resistance
between the connections
- The resistance of the cathode
(heating) should be approx.
0.5 Ohm.
- The resistance of the
connections to the mass of
the casing must be infinite.
Measuring the high-voltage capacitor
Small resistance increasing fast... ... ok
Small resistance remaining... ... short-circuit
Very high resistance remaining... ... interruption
In the case of a capacitor exchange, please use by all means the original capacitor.
The correct function and the values depend to a great extent on the exact capacity.
