Question about Microwave Ovens
Last night my microwave shut down completely. I had been using it without incident for the evening meal. I stopped the unit with 20 sec remaining in a warming cycle using the 60sec button. When I pushed the stop button to clear the remaining time, the entire unit shut down and all displays went dark. The unit will not revive even after unplugging and replugging. I checked the master electrical circuit panel to insure the outlet has power and all is fine there. I understand that there may be a fuse that can be user serviced. I have an electronics background if it needs more than the average user. We have enjoyed this unit since 1996 without incident; however, in this past year I have noticed a different sound as if the unit begins a little slower and then gains speed. It has not made a difference in performance. Could this be a failure of the Magnetron?
I suspect a door switch firstly followed by the diode pack, magnetron and capacitor. One or a number of these things has taken the internal fuse situated on the mains input panel near where the power cable enters.
BE VERY CAREFUL lethal voltages exist inside and not just mains voltage, many times greater!

SOURCE: Sharp microwave suddenly died !
The high voltage transformer that feed the klystron tube usually has a cartridge fuse on its 110 v side.
YOu will have to remove the case to access the electronics... the screw should be obvious...
Note.. you are handy- so the obvious (unplug first) and the even more obvious - keep fingers and metal away from all capacitors in the power supply area.
