SOURCE: Panasonic NN-P294SF dead

Yes, there will be a fuse and also on or above the magnetron, there will be a thermal cutout or thermostat, and one on the top of the cavity.

But here is our long answer on a dead microwave:

A microwave can be dead for many reasons.

If the fuse is good, it may be an open thermostat or thermal cutout / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open. Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

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.

If it goes dead or blows the breaker 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 it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

SOURCE: purchased a panasonic NN-H965 microwave and

See if this describes what's happening:

  • Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector
If so, see http://www.microwavedisplay.com/safety.txt , http://www.microwavedisplay.com/disassembly.txt and http://www.microwavedisplay.com/doorsw.txt

Otherwise, if the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.


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

SOURCE: My panasonic over the range microwave model

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

Model nn-n765 Was running made a scrapping noise then shut down now completely dead won't start no lights nothing


A wild guess: the scraping noise was a motor bearing seizing up (fan or turntable). A thermal cutout blew when something overheated. This would have taken several minutes to happen.

Alternate, and more likely explanation: the scraping noise was actually high-voltage arcing in a failed component, most probably the voltage doubler capacitor. This would blow the fuse. Replace both the capacitor and diode; the diode was probably overloaded and could fail at any time if it hasn't already. At $5-$10, it's cheap insurance against having to fix the thing twice.

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.

The fuse is usually a 250V 15 or 20 AMP and can be found at any hardware store. As for those screws...those are special tamper proof screws made to keep the average consumer out of dangerous appliances. There's about 4000 volts inside a microwave oven when it is energized. That's why the manufacturers don't want the average Joe tampering with it. You can, however, buy the tool required to get inside the unit for a reasonable price. I think it's less than $30 and I know Craftsman makes it. The line fuse is located on or near the input line filter board. Just follow the input power cord and you will find it. Just keep in mind, that if the fuse is blown, it usually blows for a reason. You may have other problems. Let me know if this helps you.

Panasonic NN-S789WC - No power on Display, Fuse OK, bulb Lights


The fuse will be a white or gray ceramic fuse, and you really can't tell if it's blown without actually measuring it. If a new fuse blows when you hit START, you probably have a shorted high voltage capacitor. If you have replaced the fuse and still have no display, then it sounds like there's a problem on the control board. The control board has a built-in surge protector which can short (and smoke) and when it does, it will cut the power to the control board, but not blow the fuse. We repair these nationwide for only $39.95 postpaid. If you or a friend want to check it out or send the control unit in for serivce, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
