Question about Panasonic NN-H264 Microwave Oven

Microwave stopped working while cooking. Is there a fuse?

Where is the fuse located for the over the range microwave oven models nn-h264/s254. The microwave is not working. It is plugged in and the outlet that it is on is working. Wondering if there is a fuse somewhere on the microwave that may be blown.

If the display is not working, there is a fuse inside the cabinet. You will need to take the unit down from the wall and open it up.

Chances are, either the controller board has failed, or something having to do with the magnetron, transformer, diode or capacitor (the microwave circuit.). More likely it's the controller, as when the microwave circuit fails, the display usually continues to display.

ALWAYS REPLACE THE FUSE WITH A FUSE OF THE SAME RATING!

Hello dutch.

This is an excellent microwave, over the range, white only. Here is a link to all of the features, and even the owner manual http://www2.panasonic.com/consumer-electronics/support/Home-Appliances/Microwave-Ovens/Over-the-Range-Microwaves/Technical-Specification/model.NN-S254WF.T#ts

My model is nn-s253wf, micowave stopped working, no power, checked circuit breaker, is ok ?, unplugged, then plugged back in, still no power ?


Inside the external case and usually to the right left ( from Front) in some models There is a 30 amp fuse ( This may vatry on oven output amperage) Replace that and you should be back in cook mode.
Removing the case you should remember to disconnect from the power plug.

My NN-S254 Microwave comes on intermittently, mostly dead


Try cleaning (pull the power cord plug first) the inner side of the sheet metal waveguide which may have a layer of grease that could short out the microwaves. This waveguide runs from the magnetron base over to the cooking cavity and usually can be removed by undoing some sheet metal screws along it's length. There is a fan-like device called a 'stirrer' that is located near the cavity opening under the wave guide and it should be cleaned also along with the cavity entry window. Hope this helps!

Microwave fuses are normally located either on a filter board near where the power cord comes in, behind the control panel between the door switches, or behind the control panel in a hodler, sometimes on the floor of the chassis.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa.

At our site, we have a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can find an authorized Panasonic servicer here.

You can order Panasonic parts from Tritronics, but if you don't find what you're looking for there, try here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

I have a panasonic range microwave oven model NN-H264/S254 clock cannot be set. (It use to work but no longer can be set)


Sounds like you disabled the clock function. If you do not have the user manual, you can get a copy at this website and use the function keys to reactivate and set the clock...

http://safemanuals.com/user-guide-instructions-owner-manual/PANASONIC/NN-H264-_E

I belive the information you seek is on page 12 of the manual.
Hope that helps...

Panasonic microwave does not heat , but the rest seem's to work?


High voltage parts are suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing either the magnatron or the high-voltage capacitor and diode. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

It is possible that the magnatron is bad but hard to say on a no heat problem without checking all components. A lot of model give 5-7 yr warranty on that part.

This door screen as it's called protects the metal mesh screen from moisture and food debris. The door screen must be replaced or the mesh screen can arc and be damaged, which can lead to microwave leakage. You can order a new screen from Panasonic at: http://www.pasc.panasonic.com/Epartr/PartsListChoice.asp It may be this part: F31455H00AP DOOR SCREEN A 5.75 But it might be better to call Panasonic at 800-833-9626 and be sure this is the right part. Be sure to have your FULL model nuber (with suffix) when you call. Be sure to use a cleaner like acetone, etc. to remove all the old adhesive before applying the ne wone, or it will not stick. The door must be squeaky clean and dry.
