Magnetron testing
 

Did magnetrons can be tested by simple ways? for example, using a
Digital Multimeter
How do I know if a magnetron is still good or defective?
Is there an average measure o test between the magnetron's terminals
That could be indicative of a failure?

Its hard to tell on these new invertor ovens ..The tube can test totaly
normal on an ohm meter but not work in the oven .

Invertor power supply or not, this is true. Test the filament, test for
shorts, closely examine for physical problems like cracked magnets.
Beyond that, ruling out other causes and then going for a replacement
is about the only safe option.

Agreed, either it will or will not function. Open filament or shorts to the
case tend to be common failures, cracked or broken magnets due to
overheating or mechanical stress. Continuity check across the filaments for
low reading and from filament leads to case for open.
