20 Most Recent Panasonic NN-S950BA Microwave Oven Questions & Answers


No sorry the issue will be with eiher the inverter, the magnetron or the main timer board. There is a tracer signal that comunicates through these components and if it doesnt get to where it is supposed to go it wil just shut off, the big hint at that is the time interval. It is not something like a sensor heating up and causing a fault. it is not running long enough to get any thing hot it is in the electroincs. Too expoensive to repair, im sorry better to get a new one. Good Luck

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

It may be that the wheels on the support may be a bit dry. You can use a tiny amount of cooking spray or cooking oil to try to lube it.

Petroleum-based lubricants are not advised in food preparation areas such as the inside of the oven.

You'll want to be sure the support and the floor of the oven are very clean before applying the spray.

If that fixes it, great, but if it fails again in a short time, then the support needs to be replaced.

I have just had this problem where the oven will only run for 5 seconds and then turns off model #NNS561. Cant find any solution.

It's possible that the vents got blocked. If it vents to the outside, look for debris in the vent exit at the side or attic of the home. If you're lucky, these will dry put (sometimes it helps to remove the cover) but sometimes the excess moisture gets in and cannot get out. This causes a keypad or control board failure. Please post an update if you still need help.

Prepare yourself for an expensive repair. If it is the older style with a large mains transformer, it may be just a blown fuse but the newer switching power modules will have serious issues.

That is an odd series of events. Microwave ovens don't have a reset button but they do have a slow blow fuse. It is no point replacing it because you have a more serious short circuit that tripped the breaker immediately. You can't work on Microwave ovens yourself as they are so dangerous inside. Also the case is fixed with special security screws. Panasonic are pretty much the best in the business and I have used many in a commercial kitchens environment. The old ones are much better made than any new one these days, so it is well worth getting it repaired. Pull it out and take in. https://www.google.com/search?safe=off&rlz=1C1QJDB_enCA643CA644&sxsrf=ALeKk03OWWscqQi9U5hA-vDA8sHRuHMF2A%3A1615660600337&ei=OAZNYKfnE--3ggeCxZbQCw&q=panasonic+microwave+service+near+me ..

  1. Unplug the microwave from electrical power.
  2. Remove all the screws holding the outer wrapper in place, back and sides (note which screws fit in which locations).
  3. From the rear lift the wrapper slightly and it should slip back to release tabs/flaps located along the front. (A putty knife or flat blade screwdriver can help.)
  4. Components inside have sharp edges and there may be considerable residual electrical power retained that can cause injury - proceed with caution!
  5. Inside the component compartment (on the right hand side) and just behind the control panel and door latch assembly you will see the oven cavity light assembly. Check for a bad light and replace as needed.
  6. Exercise caution during reassembly to confirm all wires are in their proper location and nothing is pinched, trapped or otherwise going to cause problems upon reassembly.
  7. Restore electrical power and check operation.

Either the magnetron, power board or both have failed.

The directions to access the charcoal filter are given in the basic operation manual on page 25 (page 27 of the PDF). First tilt the vent grille louver above the door of the microwave down towards yourself. (The vent grille goes across the entire width of the microwave). Next remove three screws, one on each side and one in the center top of the vent grille. Remove the vent grille. Place your finger under the bottom of the standard charcoal filter in the center of this filter. Use that finger to slide the filter forward. Since the replacement filter gets secured with two screws, remove the screws if you can't slide the filter forward. This manual is available on the Panasonic support site: https://shop.panasonic.com/support-only/NN-P295SF.html . The current link to the manual is ftp://ftp.panasonic.com/microwaveoven/om/nn-p295bf_mul_om.pdf . I hope this helps. Cindy Wells

The transformer is probably drawing too much power by a low resistance or a short somewhere on the secondary's side. The components on that side include the HV cap, the HV diode, and the magnetron all of which should be tested. I would try the cap first but make sure you discharge it before operating on it.

Purchase a replacement lamp from somewhere like espares or the like. It should be a standard E17 or SES 20Watt bulb.

I don't think the door film is part of the shielding - mostly the shielding is a sheet of perforated metal sandwiched in the door and covering the glass window. I think the glass film is just there to make it seem dark and mysterious until there is something going on inside. Try shining a flashlight through the door and see if there is in fact a perforated sheet... Microwave energy leakage meters are commercially available though they are less used these days as users have increased confidence. When a new microwave is obtained it is a good idea to accurately time the boiling of a measured quantity of water as a performance benchmark and then repeat the experiment at intervals - any significant extension of the time taken signals it is time for maintenance because the lost energy could be due to leakage...

This looks like it. It is a standard Philips compact florescent. You can get them at home Depot, or here https://www.repairclinic.com/PartDetail/Light-Bulb/FFV3420085S/4546044 ..
