Hi every one ;:)

I have a samsung microwave oven that has stoped heating at all!

it seems to work ok  ( light, fan, and the timer) but it just dous'nt heat what so ever!

I  tested the primery circuit and its OK,

I also teted the secondry HV transformer and it seems to be OK

the only thing that i'm suspecting is the HV capacitor !

 thats because there is no voltage intering the magnitron,, and therfor no radiowave is genarated,,,,!

I need some info on how to test the HV capacitor please

and alos if any othe info in regards to getting this baby its life again.  

thanks in advance for any of  your  feed back:D
