Nothing, just cut it off 1st time, 2nd time didn't do it, 3rd time started again and haven't used since.
this means that your magnetron is arching out and will be quite an extensive repair and cost quite a bit to correct unfortunately. Here is a link to the magnetron you will need to replace, but in addition to that you will need to sand down the wave guide and repaint it so that it doesn't arch out in the future. The wave guide is the box that the antenna of the magnetron enters. CLICK HERE FOR MAGNETRON
