I have found that the common cause for this problem is either the 'High Voltage Fuse (HV fuse)' or the 'Magnatron Assembly'. In some instances it can easily be both.
My advice is to read throughly how to discharge a 'High Voltage Capacitor (HV capacitor)' to avoid any injury or worse yet, death.
After doing so you can find the HV fuse runing from the HV capacitor, it will be inside a small plastic casing, you will be able to see with the naked eye if it has blown. If so, replace it.
As for the magnatron Assembly, it looks like a large silver cube with a series of magnets inside it, they are not as easy to test to see if they are faulty or not so if the fuse doesnt repair the issue, replace the magnatron assembly as well. I hope this offers some help. Good luck.
