hi,
remember Google is your friend
......
Test 1
Unplug the oven (make sure the oven is completely disconnected from any power source)
DISCHARGE ALL HIGH VOLTAGE CAPACITORS. (Procedure)
Carefully remove all leads from the magnetron terminals. Proper wiring is important so make notes of the wire locations.
Set the ohmmeter to its lowest resistance scale.
Measure the resistance from one magnetron terminal to the other in either direction.
The magnetron filament resistance should be less than one ohm.
Test 2
With the meter set to the highest resistance scale, check from the magnetron terminals to the metal magnetron housing. (Be careful not to touch the meter leads as this will result in a false reading).
The meter should read infinity (open circuit) regardless of meter polarity.
Even a slight reading would indicate a defective magnetron.

Thanks Dave and EF too ....google is great!!
