This microwave would not heat. I got an OEM replacement diode and magnetron. I first removed and tested the old diode. It was bad(open) both directions. I first took precautions with capacitor, of course. So, I replaced diode and it heated. I only tested heating water twice for 90 sec. After I left, customer called and said it was not heating again. I never checked the magnetron. Should I get another new diode and replace it again AND the magnetron?

Hi,

I only tested heating water twice for 90 sec.

Was the water near boiling after 90 seconds?

I first removed and tested the old diode. It was bad(open) both directions.

We got to the point now if the mag is bad we include the diode, and if the diode is bad we include the mag as they can damage each other.

Some places are saying this mag is NLA now

The water was near boiling after 90 sec. I have the mag, guess I need another diode. The capacitor should be ok, right? Not much to go wrong with that.
