The capacitor is definitely good. Otherwise it will blow the fuse.
The HV transformer is the last thing to think about because their failure is very rare.
You can find the instructions on how to check the diode in one of our previous threads; diode testing
If the diode is good then the magnetron is the culprit.
Only you can decide if it worth it.
- The magnetron Part number: W10210845
- The diode Part number: W10163432
