I have same problem. Disconnect the power. Take the 3 screws out of the top of vented front thus exposing 2 screws that hold down the touch pad .remove them and move touch pad out of the front and out of the way. on the extreme top right within the compartment there is a circuit board that has a fuse on it. replace the fuse and try to restart the microwave. if the fuse blows again you have a major problem probably the magnetron. If you need further help call me (403)870 9110.........Ron

I have a Panasonic NN-L829BA Microwave. No power or lights - is there an internal fuse and how can I locate & replace it?


Yes this unit should have a fuse, The difficulty is replacing. A qualified technician needs to do the work. Of course the power must be disconnected.

Where is the high voltage capacitor at on panasonic microwave model nn-sn960s


behind the control panel,while your checking the h.v. cap check the h.v. diode for a shorted condition as this will also blow the 20 amp fuse too

No power on microwave panasonic NN-S255


It all depends on your full model number (you left off the suffix) but one version's service manual is here.

In some cases, it is a fuse or thermostat / thermal cutout / TCO, in others a surge has occurred, requiring circuit board repair.

This surge can be from the power line, or due to blown cooktop bulbs.

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

NN-T964SF 1250 Watts Microwave Oven: my microwave went dead and wouldn't turn on at all...


Sounds like a blown fuse. Carefully remove the cover, and the fuse in directly behind the power cord on the top. Radioshack sells 15A ceramic replacements.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

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.

Panasonic nn-p295 blows buss fuse when turned on for cooking


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer. But this is likely an inverter model, so it wouldn't have one and would be some other component in the inverter I'd say.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

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

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

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.
