My Panasonic NN-T994 Microwave oven died today. Would run for a few seconds with a clicking sound and an electrical smell. I removed the cover, restarted and found arcing from the area of what I think is the inverter board...Is this a common fault or a bad magnetron or time buy a new microwave? PS: Non emergency on my part as I put my old, old very old Toshiba back in service/ Would appreciate advice..Thanks in advance

Starts and runs for 5 seconds and clicks off and Problem with the Panasonic NN-S963BF / NN-S963WF 1350 Watts Microwave Oven

my microwave shuts off after a few seconds. is there a fuse that needs replacing?

I have the NN-T994 SFR model and it had a switch that was staying depressed. I removed the screws to (in my case) the stainless steel cabinet, removed the cabinet and unhooked the wires to lay it aside. Found that the switch was cracked or broken, glued it back exactly as it was, then put the cabinet back on and it fixed it! Now about a year later, I have another problem...oh well. Hope this works on yours.

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.

Remove the cover after pulling the power plug. Check the transformer and large capacitor for signs of overheating. If they look ok, then remove the sheet metal wave-guide from the area where the energy enters the cooking cavity. Under the wave guide is a fan-like device called a stirrer that has a plastic bearing. This stirrer bearing is commonly arced over (when the oven is operated with nothing to heat in it). Usually the bearing looks good, but has arced internally. Replace the stirrer as a unit. The machine can be operated with the case off and a cup of water for a load, but keep you hands clear. Look for smoke.

could it be that i didn't follow the manuel because i got it second hand or is it because something is wrong with it,and i have to get it fixed.

That would most likely be a problem with the inverter or magnetron.

having trouble clicking buttons.

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!

Classic symptom of a defective inverter. It it's under warranty, you're probably in luck. If not, expect repair costs of about $120-150. If you can find a servider who will repair the inverter instead of just replacing it, you can save some money. If you or a friend can replace it yourself, you'll really save, assuming you follow safe procedures. You can find my file "safety.txt" via a Yahoo search. It is part # A606Y5X00AP for model NN-T993S and runs $62.83 plus shipping. The inverter can be gotten from Panasonic at http://www.pasc.panasonic.com/epartr
