Chances are there is a short on the power supply board. at this point you may need to replace it.

Replace thermal fuse for LG microwave LMV1813ST


If too much current passes through the microwave circuitry, the line fuse will blow. If the line fuse blows, the microwave won't start. To determine if the line fuse is at fault, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. In addition, you should investigate and resolve the problem that caused the fuse to blow. If you don't resolve the underlying issue, the new fuse will blow too. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the line fuse.)

Can i use another 4a 250v fuse for my cerwin vega LS12 if its not a (slow blow) ,and what would be the outcome


Fuses have different blow characteristics. Such to protect components differently. An extremely fast fuse would protect sensitive components like tweeters and slower fuse will allow transcients to pass and blow on long time fault. If you put a slow blow in place of fast blow, it won't blow as quickly, but it could allow the protected device to be damaged. In reverse, you put a fast blow in place of slow blow, it will blow at normal transcients and be a nuscience to always replace.
You can cross to a fuse of different manufacturer. The reliable manufacturers will have detailed datasheet and subsitute or similar fuse to the fuse you are looking for.

Samsung dlp 5065w keeps blowing fuse


samsung motherboards are bad for going out. they are 125 dollars online, if you have the technical skills to replace them.. basically just plug and play, with LOTS of screws to take off.

What kind of fuses are needed for JVC HR J692U VCR? Slow blow or fast acting? What termination style 1.25 a 250 volts.


I don't know what you mean on "termination style" but I can help you on the fuse type. If you have the dead fuse look inside and see if you can see a coil of wire. If you can it's a slow blow. If you haven't got it or it looks just like a broken wire or it's gone too much, then fit a fast blow. It won't make any difference. If it blows again after a new one is fitted then it's not because it's a fast blow. It means you have a short-circuited semiconductor somewhere causing it to blow.

Please let me know if the speaker output fuses on a KAV2250 are fast or slow blow?


If you have the original fuses you might be able to tell from that. For example are there remains of a coil? If so it's a slow blow.
However you can fit fast blow in there, it should work normally with that. If it blows again it will be an short in a semi-conductor that causes it not the fuse type.

My fan fuse blows when it gets hot


About the only thing that would cause the fan fuse to blow is either the fan has a problem and is dragging or a short in the wiring. I would bet the fan motor is probably bad. The hoses and thermostat have nothing to do with the fan motor fuse blowing.

Blown fuse


You can try a slow blow fuse, but more than likely there is some other issue in the unit that is drawing too much current. By no means would you want to increase the amperage of the fuse. it could cause a fire.
