Microwave dead protection testing

so, our microwave has given up the Ghost :/ She is 20 years old and has always worked. She has a built-in Grill, so perfect for frozen pizza or my student life. Accordingly I want to replace it for a new (also because of the durability). Also know I where, how long the pizza in it must be, so it's just perfectly done.

So, so the problem is that the transformer loud buzzing and nothing is hot. The transformer seems to be in order. It is still a good dude, where the primary winding of copper is HV testing. I have the secondary side of the capacitor disconnected and short run = no more hum. Transformer is so fine. Already I have exchanged the same types of the diode, but it brought no improvement. I have measured the capacitor with a DMM and towards this end were 0, 7µF (from 1, 2µF standing on it) out. But I don't know if that's true... Yes a discharge resistor is integrated there and maybe it falsifies the result... : think: but accepted the measurement result is true, should bring only a lower power the magnetron, or? My guess is that the voltage by the low capacity not enough of the voltage doubler to make to swing the magnetron. Otherwise no longer occurs because to me... I don't know but yes also, whether the result is correct. HM...
