The magnetron was already replace, the high voltage diode was replace and the door sw was replace. The buzzing happens when the door is close, we can not do any cooking I'm runing out of parts to replace.
ANSWER Hello Josue. Did you replace all three switches for the door, or just one?. If just one, the other switches 3405-001033 3405-001034, may be bad on the unit. Also the switches needs to be installed in the proper locations. Hope this helps.
