HOW TO TEST

[PRASH]

I have a National microwave oven in repair.It was dead I restored it by replacing one defective microswitch.But now it becomes too hot and trip when we try to cook.Also it takes too much of time in cooking. I suspect on the capacitor and diodes at the magnetron because the magnetron also is getting very hot. I want to know if there is any means to check these things (the cap &the diodes).
