Panasonic NN-S740BA Microwave oven

Type S333 indicates something about the internal build; it's not the model number. Most Panasonic microwaves have a model number that starts with NN-S followed by 3 numbers and several letters. One microwave with the Type S333 on the serial number plate is the NN-S740BA. The manual for that is on the product support page: http://shop.panasonic.com/support-only/NN-S740BA.html . The direct link to the manual is ftp://ftp.panasonic.com/microwaveoven/om/nn-s740_mul_om.pdf .

Please check for the actual model number. Add a comment with that model number if you would like me to search for the manual.

I hope this helps.

You have a faulty interlock switch (which the door operates).
This needs to be renewed by a qualified microwave service technician ASAP.
A potential hazard if not fixed immediately!

internal short that can damage your control panel but do not try to fix it yourself its got 4000v !!! sorry :( your life worth more then this microwave.

If my wife saw that in our microwave, she would make me replace it after she finished freaking out two hours later. To get into the display, you will need to unplug the microwave and remove the cover to get into the display from the back. Watch out what you touch because you could get zapped by one of the capacitors.

In most cases, this is a problem with the inverter or a bad magnetron.

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. You can find one here.
