Fist if it's plugged into a GFI socket,reset it by pressing the red button in the center back in & try it again. If that trips again,replace the microwave.If you dare, be carefull & unplug it, take the cover off. Should be held on by a few screws, & check the fuse inside. If it's solid white, then you need to remove it & check it for continuity with a multi-meter(ohm meter will do). If it's the clear kind, just look for the filiment to be burnt,like a light bulb. You can replace either kind with a standard glass fuse of the same amp rating. Whatever you do DON'T touch any of the circuits with bare hands! There's a transformer that holds enough juice in it to fry 5 people for months,even unplugged. If this scares you, it should. If you are uncertain about trying this,trow it out & buy a new one. Don't get hurt.

My Neff microwave has lost all power. It tripped the main switch at my fuse box. I have re-set the switch but still no power. Any ideas. Is there a fuse in the microwave and if so where is it?


There are two or more fuses on microwaves, but when they cut the power feed it is for something, if you bridge them you will find that your oven doesn't work properly, it will make weird noises and produce a power low in your home. If you want to check it, the main fuse use to be inside a plasitc tube with two wires on it's edges, one conected to a big condensator, and another one to the inner circuit.

Microwave won't work/no power


Then you have blown a fuse. Check inside the oven chamber and look for missing powder paint or signs of arcing, if so dispose of the microwave. If the inside is good remove all the screws and remove the cover. Replace the fuse. If the magnetron was making louder noises prior then replace the magnetron. Since the fuse went the giant capacitor is likely bad. While the cabinet is open make sure to look for burned wires, check the continuity of thermal cutoffs, and check the main circuit-board for burned traces or components. The relays in most electronics are known for arcing (spot welding) and staying in the wrong position. Tap them hard with the back end of a screwdriver. During all of this use safe electrical practices by having the power cord unplugged. The capacitor could still have a high charge on it so be careful.

No power - blown fuse?


If it was run without the fan a thermal protect device was more than likely taken out. Check for that and replace the fan.

My model nn-p295wf microwave stopped working ,all power just stopped, about a year ago. I took it to a repair shop and they replaced the DIODE and the fuse, then it worked again. Afew weeks ago it happened...


Replace the magnetron, safety fuse and diode as a set and check the door interlock switches.
That should get it working for another year or so.
Don't forget microwave mains fuses are special sand filled and semisurge type.

Microwave doesnt power up, suddenly stopped working, can it be the fuse? ow do u check if the fuse is OK?


If there is no power at all then it could be the internal power fuse has blown, there could also be other parts faulty also. I would not recommend you to check this if you are not electricallly qualified as a microwave is a very dangerous piece of equipment to tamper with, even if there is no power to it. It would be best to call a service engineer to check it over for you.

Check for a circuit breaker on the back. If nothing, pull the plug and remove the case. Look for a blown fuse. If so, look for a shorted high voltage diode in the magnetron power supply or a shorted stirrer bearing located above or beside the cavity area where the microwaves enter. The stirrer is a metal fan-like device with a plastic bearing that often arcs internally. That shorts the microwaves out and blows a fuse. Replace the stirrer.

My Panasonic The Genius microwave just stopped working not getting any power to display. Wondering if it is the fuse and where that would be located.


HI, if this unit is totally dead, this may be a power inverter issue. there is a fuse located on this board inside the unit. you will need to gain access to this board and fuse by removing the outer cover. there should be a few screws on the outside of the microwave to remove.

Check the In-line fuse for its value. if the fuse is good, replace the power unit(inverter board)

Microwave stopped working when i pushed the start button


Yes. The white inside the glass that you are describing is a blown fuse. To find out what size fuse it is look around the base or top of the fuse. You will see engraved something like "125V 5A. You can pick these up at Home Depot or Lowes in the electrical isle. You can also type www.google.com and enter the word "fuse" and then the size it is. (125V 5A) If you have found this information at all helpfull, please rate my solution. Thanks D. Lange

Microwave stopped working all of a sudden. NO power supply. I tried placing at different places.But no use..I ddidn't see any problem before it stopped working..


the most common problem with microwaves is the door protection circuit blows a fuse. the door catches operate switch that if they do not operate correctly( normally after the door has been slammed). the good part is they place the fuse inside the casing. so remove the power open the casing( several screws) and check all the fuses in side.
