The owner's manual won;t tell you that, only the repair or service manual.
While we don't have that exact model, we do have the manual for a similar model uploaded here.
A microwave can be dead for many reasons.
It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.
If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.
Then when it cools, it closes the circuit and allows power through again.
When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
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.
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.
You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.
If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.
If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

i just took out my fuse on the same model. you have to pull down the microwave and take cover off. there should be like 6 screws on backside and cover will slide back and off. then you will see a fuse cover with a small cylinder fuse in a plastic cover. pull it out and check continuity with volt meter. mine unfortunately came up good still, so i dont know what kinda problem mine is having. had a short in light and it popped and power was gone. good luck!!

The outside bottom of your microwave usually has a belt hidden underneath a small cover directly under the turntable. This belt sometimes falls off or breaks, and sometimes the motor that turns the belt fails. Most time the motor can be found if you remove the main top cover of the microwave, about 10 screws.
Parts can be easily found at your local appliance parts store.
Best of luck.

The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts, then most likely the magnetron is done and a new microwave is the way to go.
Let me know how this works out for you.

Most microwave ovens have a fuse. It may be a cartridge-type. You will need to remove the fuse from its socket and use an ohmmeter to check fuse continuity (that current can pass through it). If the reading is very high (kilo-ohms or mega-ohms), the fuse has blown and will need to be replaced.
Be SURE the microwave is unplugged before doing any testing!!!
