Yes, there is main AC fuse in the power supply module, it is usually marked on the board as F??.
If is has blown fuse, then you will need to Ohm out the circuits to see if it has any shorted out components such as brdige rectifiers, MOSFET, ECT.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Suddenly microwave stopped working


(would really like more info- digital number dead as well?)

(assuming completely dead) Could be a couple of things:
- blown fuses (inside, relatively easy to replace, std size avail at Raioshack) <-- most likely
- cut/loose power cord connection inside.
- (unlikely but worse case scenario) Door was closed crooked- one tong hit one door switch before the other- causing a short circuit internally that "self destructs" the microwave to prevent it ever operating with an open (or even crookedly ajar) door, irradiating any users. Typically it just blows the fuses, but if fuses blow immediately upon replacing and turning power on, then possibly one of the switches fused or melted internally, and needs to be replaced.

How do I replace the internal fuse on my Over the Range GE microwave? I opened the microwave door and and there was a quick spark after which the microwave went dead with no power. I have checked the...


I would say the lamp popped and took the fuse, so you will need to replace the lamp also.

Dead appliance, power on wall outlet.

YOUR SAFETY IS PARRAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

DEAD, NO TURN ON, CHECKED INTERNAL FUSE OK


If the internal fuse is okay, then what you got here is a bad power supply. Many power supply's do die with the internal fuse intact what happends is the High voltage tranformer or relay goes out on you causing this to happed, Best thing to do is replace the unit becuase a new power supply would cost you more then the unit new. Let me know if you have any question.

please do not forget to rate.

Dead Microwave - Internal Fuse?


After replacing the internal fuse (see other posts to see how I did it) the microwave is working fine (so far). We have used it 5 or 6 times without any issues.

Heard a pop then screen went blank. Now TV wont turn on.


Sounds like your fuse.

If not the fuse in your plug, then the internal fuse in the TV. to get too this you need to open the TV by taking off the back plastic panel and look at the fuse.

the fuse is the glass tube on the board, will no doubt be near where the power cord connects to the TV. and are easy to replace with another fuse. you will know soon as you open it if its blown as the little glass tube will be blackened or the little wire inside the tube will be missing or severed.

Fuses in TVs are actually designed to blow over time with ware (usually to last a bit longer then the warranty time frame) so after the cover has ended the TV can go in for repair work at extra cost. Its a little known fact.
