Is it an electrical spark noise or is it actually sparking inside your microwave oven? Watch as you heat something. This also might appear to be the bulb flickering, when it's actually a sparking. I only know how to fix it if it's an actual spark, or what might be called "arcing." This is not supposed to happen.

Inside your microwave, there is a "cover" over the area where your bulb is. If this cover has a burned place in it, or an actual hole in it, then it's your "waveguide cover." And this is the easiest thing to repair. I myself will not attempt any electrical repair, but this waveguide cover was a breeze.

You have to purchase replacement material... Then, when the replacement material arrives, remove the wave guide cover from your microwave, trace it, cut it out and put the new one in. It is very easy to fix. Sort of like paper dolls....

Google "waveguide cover" and you're on your way! IF that's the problem....

Sharp Microwave Oven Model R-403kk-T


Are you talking about the light inside the microwave? The front vent I think will allow you to get to the bulb. Should be a couple of small scrrews holding the vent cover on, remove them take vent off. Start it up again and see if the light bulb wiring or socket is arcing

Light bulb going out


Unplug your unit then you have to remove the cover from the microwave. Just remove the screws that are around and in the back if there are any. once you remove the cover you should have access to your bulb. Befor removing the cover just inspect the inside of the oven to make syre that ther is no access plate in there to remove the bulb. I hope this helps. Don,t forget to rate my answer, thanks.

Shuts off but everything else works


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.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

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

1800 XL JVM1860BD - won't work


It sounds like your controller may be failing. Or it could be an electrical line problem. Any other electrical itmes giving you trouble? Has anyone measured the voltage level of your power line? It should be around 110-125 volts AC. If it's significantly lower or higher, you may have a bad connection in your breaker panel or in the wiring leading to the home.
