Panasonic NN-S760WC sparked and smells burn, should I have it fixed

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

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

See if this describes what's happening:

• Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector

If so, see http://www.microwavedisplay.com/safety.txt , http://www.microwavedisplay.com/disassembly.txt and http://www.microwavedisplay.com/doorsw.txt

Otherwise, if the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

My panasonic microwave model # NN-S540BFW stops after 4 seconds after you hit the start button and cuts off on its own. What is wrong with my microwave?

If it is burning and arcing at the antenna, it is probably arcing in the wave guide area. Probably will have to replace unit. I have had some success by removing the antenna, sanding and repainting the burnt areas of the cavity and sanding off any burnt marks on the antenna. Need to look at top of mag to see if also arcing there too.

if you are talking about the transformer then it will need replacing , because it is about to quit on you and then the microwave will not work at all
are you going to do the repair yourself? or are you going to need to take it to a qualified service shop?

if the is a convection model then the covection coill will smell that way if there is a geese build up and should be ok to use. however you should only smell that if you are using the convection mode.

Replace the h.v. capacitor (the silver can mounted in back under the magnatron) and the h.v. diode and it will be fine.
Hope Ya Fix It!

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