    The
    first thing I would suggest is a hard reset. Unplug the unit for a
    minute or so. Then plug it back in, set the clock and try again.


    If that doesn't work, leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

SOURCE: Microwave shuts off after 3 seconds

Although your model number doesn't seem to show up, the NNS950-series units are powered by an high-voltage inverter. And yours has failed. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Sometimes a whole new inverter is cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized appliance / microwave repair shops and ask then specifically about inverter component-level repair and simple inverter replacement costs for your exact model number.

SOURCE: Panasonic Microwave Turn table rotates when door is open

Found this Panasonic post in the Samsung section!

If it moves just a tiny bit when the door opens and then stops, that's normal.

If it keeps running when the door is open, that's usually due to a bad door switch or broken / loose door switch mount.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

You may instead have a failed keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

If you would like to have us do this for you, we do that for $39.95 plus part costs, which depends on the exact model, one of these:

SOURCE: Panasonic NN-P295 Cooktop Light not working

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

SOURCE: Can't open microwave door

It sounds like the push to open lever is cracked or broken. You have to remove the 'wrapper' to open the door manually from the inside to check the 'door keys' or door hooks to make sure that they are in tact. Then, check the door opening lever between the 'push to open button' and the lower door key.

SOURCE: Door Release Button not working on Panasonic Microwave NN-T664SFT

The problem I had experienced with the Door not opening easily will be resolved by removing the micowave oven top cover with a tamper proof torx head, replacing the door switch and reinstalling the top cover.

PANASONIC Microwave Inverter #NN-SD697S. Everything works except the START button. Works sometimes, and not other times. Checked outlet, all was good.


This is either the door sensing switch (most likely) or a bad membrane switch [start switch] (that's what Panasonic calls it) on the touch pad. The contacts on the door sensing switch can be slightly contaminated and not read "zero ohms" to the control PCB. The control board thinks that the door is open and it will not allow the cook cycle to start.

NN-T774 INVERTER STOPPED WORKING AFTER 4 WEEKS


Check to make sure one of the plastic hooks on the door was not broken off. If both door hook latches are functional then the most likely cause of your problem is one of the latch switches located behind the control panel. These switches will fail if the oven user opens the door frequently BEFORE the cook cycle ends. Always push STOP/RESET before opening any microwave oven door.
