Question about Microwave Ovens

Microwave -- Panasonic NN-S543BFR

Suddenly, it doesn't work. The light comes on, it beeps when you hit the start button, but nothing happens. No fan, no turntable, no heat, nothing. My wife says it stinks like hot or smoke.
Looks like it's dead, Jim.

    Update: I unplugged it for a while and tried again. This time, after about 3 seconds, a cloud of white smoke erupted from under the microwave. I'm pretty sure he's dead, now. I don't suppose there's something simple I could replace? I hate to just junk the thing if there's something I can do.

I would say either the high voltage transformer or a component on the inverter board has failed.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.

Panasonic microwave NN-S666BA


No! the main fuse is okay because you would not have any power. I would check all door switches because they control light, fan, and turntable. If you are handy with a meter, set to ohms, disconnect one wire on side of switch, use meter to test, readings should show open/short when pressing the button and releasing it, replace wire to switch and repeat, if you hit one with the same readings pressed in or out, change the switch.

Panasonic Microwave NN-T993SF has no power. Was working and suddenly the power went out like it was unplugged. It is not our fuses or cord but something in the microwave itself. Is there a fuse or...


most microwaves do have an internal ceramic fuse either 15 amp or 20 amp the cover has to come off to locate it usually at the top just behind the control board. do not touch the high voltage capacitor as it holds a charge even when the unit is unplugged.
