So I check the other new one and it's also open both ways. So either I'm testing the diodes wrong or got two faulty "new" diodes.
Or your tester isn't putting out a high enough voltage to exceed the threshold voltage of the diodes, in which case it would read open both ways.

this is what I am leaning towards.
Just my tech data all says to do a test from Anode to Cathode and then reverse it.
The systems is in a microwave and goes up to 3,000 volts. That's what is applied to the Diode which gives it a path from ground. When a microwave buzzes loud, usually its a bad diode.
I already swapped the magnetron and the Transformer to see.
Maybe I'll try a different magnetron.
After this, my company will no longer work on Microwaves. They just aren't worth the headache. Easily the most complicated of appliances.
