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

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

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

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.

See: http://www.microwavedisplay.com/doorsw.txt

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.

Lg grill wavedom model no MG-6644B

It all depends which fuse is it the plug fuse as used in the UK or the internal fuse? If it the internal fuse either the magnatron has gone S/C or the high voltage rectifiers have gone S/C and will need replacing the the indentical components

Why r 872 blowing 8w ceramic fuse repeatedly

Most microwaves usually use 15 amp fuses and not 8's. If it keeps blowing fuses there is a short circuit somewhere and you would need to track that down to stop your problem. A frequent possibility might be one of the micro switches in the door circuit.

MODEL R-8476

You may need to find a service person to check this for you, but it sounds like you may have a micro-switch for the door that has gone bad. I have run into this a few times and found that to be the cause. What happens is the bad switch causes a direct short when you turn it on and that blows the fuse to protect the rest of the microwave. Hope this helps.

Fuse blown and replaced it but keeps blowing new fuse

Either s door switch is defective, or the capacitor is shorted.
If it blows immediately, check the door switches.
If it blows when trying to run the micro, check the high voltage capacitor. Be very cqreful when checking the capacitor as it can be very dangerous, holding a large voltage charge long after use.
Good luck.

The internal 8a ceramic fuse has blown on my Sharp platinum collection 900w microwave oven, model R-957. fuse is marked F8AH 240V and is located on a small circuit board inside the rear of the oven. is...

Don't know if this a regular problem with this unit, but for this fuse to blow, there must be a problem further downstream. Maybe with the power supply or the Magnatron.

R-8350, No power to touchpad, but interior light works

The touchpad has its own fuse which has probably blown due to a surge perhaps related to the turning on of the fridge. Removing the cover from a microwave is potentially lethal due to the large capacitor to drive the magnetron. However, this is usually well away from the front panel. If you do venture in you should first unplug the unit and when the outer cover is removed, discharge the large capacitor with well insulated pliers -= otherwise keep well away from it. The fuse you are interested in is on the pc board behind the touchpad. Replace it with exactly the same fuse (usually a slow blow fuse).

Hi our Sahrp Carousel microwave LCD panle display is not working

You have to replace the control board. Sharp has had problems with the display boards for awhile. There is no bulb or fuse you can change.

Sharp half pint

The fuse should be located on an input line filter board INSIDE the microwave. You will need to unplug and remove the outside case to get to it. Simply follow where the power cord comes in and you should see a fuse mounted on a small circuit board somewhere. This is the line filter. The fuse should be a 20 amp appliance fuse that you can purchase at any hardware store. DO NOT attempt to re-energize the oven with the cover removed. There are dangerous voltages present in the high voltage circuit (about 13,000 - 14,000 VAC). Put the outside case back on before trying an op test. Let me know if this helps.
