Help! Magnetron in microwave oven makes jackhammer noise. Answered
My microwave oven was out of order, it kept blowing up the power fuse; finally the trouble was traced to the power capacitor that was shorted.
So, the power capacity was changed and the oven worked again, but now the magnetron becomes noisy with a jackhammer noise when it is working.
This noise starts when the magnetron starts working, but it stops after some two minutes while it continues to work up to the time adjusted for it to finish its operation.
What has happened to the magnetron?
Is it possible to fix it?
On the other hand, it is my best suspicion that it is the magnetron that is making the noise and not the transformer.
What is your experience in this situation?
This is exactly the sound (click on the link below) I am getting from my microwave oven, but it does not go and on until the machine turns off; the sound stops some two minutes into the operation, and the remaining time there is no longer the sound or noise – for the remaining time it keeps ‘quiet’ up to the completion of the time period it has been adjusted to operate, or I turn the switch knob to off.
Thanks for any help or information.
