It’s a bit tough to be 100% when you’re
trying to fix stuff over the net.
But if you’re getting a real loud humm, and you
know you’re getting the high voltage to the
mag that you’re supposed to be getting then the mag
is no good. The excess hum is because of the fact that
the secondary circuit is being loaded down more than normal.
Now if you were to pull the wires off of the mag and you
were to still get a loud hum then you would need to suspect
one of the other secondary high voltage components.

(pulled mag out and found no signs off arcing on anttenna or waveguide looks great).

That doesn’t necessarily mean it’s good.
Most of the bad ones I’ve ran into don’t
usually show any visible signs of damage.

another thing is that I can never get a discharge out of the capacitor with a screwdriver even seconds after I run the microwave.could the mag be causing that too?
|
Its possible,
If there is a problem with the mag it could act as a short.
Dont forget there's also a bleed resistor built into the cap.
