I have an AEG microwave MCD2660E-m. It won't heat properly

I have an AEG microwave MCD2660E-m. It won't heat properly and have found fuse F2 on the power card blown, thought it might be the high voltage diode, replaced it but still blowing F2.

Hi the Microwave is 8 yrs old, yes it runs the whole cook time set but the F2 fuse which is 8 amps blows after about 1-2 seconds.

Hi Michael, I have tested the magnetron, across the contacts I get 0.3 ohms both directions and OL across the terminals and casing.

I replaced the high voltage diode, I have rechecked both the old one and the new one, the old one is reading 0.01 both ways on my diode function, the new one is reading OL in both directions.
Are you testing the diode in or out of the circuit?And are you familiar with your metes operations?Thanks Tech Michael
Customer: replied 1 year ago.
I am testing it out of the circuit, I am not an expert but have some knowledge.
It sounds like you may have a bad NEW diode
Customer: replied 1 year ago.
Would a faulty diode cause the fuse to blow so quickly. There are 2 fuses on the power card, the main fuse and an 8 amp fuse, it's the 8 amp one that is blowing.
Hi no unfortunately that has nothing to do with the fuse blowing.Its either going to be a bad transformer or mag tube.But usually it is the mag.I have done thousands of these hands on so I am pretty sure lol.It could be your meter isn't reading that diode correctly due to its extremely high value
Customer: replied 1 year ago.
But is that readings from the mag not ok, how do I check the transformer.
Hi, on this one you really cant be sure on the transformer. What you can do is unplug the transformer and see if it will run without blowing the fuse but even that doesnt tell you much. Its just that mot times it is the mag that is shorted.If you want to be sure, buy both parts ;-)But I would advise just the mag.Tech Mike ;-)

Ok Michael, at 8 years old I think we'll just get a new one, I've priced the 2 parts and it's hardly worth repairing. Thank you very much for your assistance, I've also learned something today so that's good.
