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?
