Question about Panasonic NN-SN657S Microwave Oven

1 Answer

Microwave runs for about 20 seconds then shuts off.

I have a Panasonic Inverter Model NN-T993SF manufactured Jun 2003. Without any significant incident, the microwave now only runs for 20 seconds and then shuts itself off. After 20 seconds, whatever was inside does not appear to have been heated.
I have bought a replacement but before I throw this out, I am wondering if it may be a simple repair where I could then use the old microwave in the basement.

My mother had the same problem and she was going to trash it. Me being an extreme environmentalist, dint wanna let it go to the scrapyard. Got it down to Mumbai India checked with the engineers down here and rectified it. Problem was with the Magnatron. You would need to replace it. Well this one's getting repaired and off to a institution in need like the Home for the Aged rather than some scrapyard.

Microwave stops mid cycle


If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

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.

Microwave stops after 24 seconds


If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

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

The 22 seconds is the giveaway.

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

Panasonic microwave 1200


This model uses an inverter to produce high voltage. That symptom is an usually indication of a problem with the inverter or a bad magnetron. I do not recommend that a person without training and experience ever work on these models. You should be able to locate a Panasonic-authorized servicer here: http://www.pasc.panasonic.com/WhereTo/FindServicer.asp?Pass=1 I would mention the exact symptom when you call so the technician can bring a new inverter with him when he comes out to repair it. Might save you having it pulled into the shop. Good luck!

Microwave shutsdown after 24 seconds, does not heat up


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
