Microwave quit working no power everything quit working

There is a fan inside that blows air across the electromagnet that cooks your food. It gets hot! The fan is most likely broken or spinning to slow to keep the electromagnet cool enough. There is a thermal sensor on the electromagnet to shut off the oven if it gets to hot to prevent it from catching on fire or melting everything inside the oven control area.

One or two of the micro switches have failed, you will need a professional to remedy the situation.

Hi,
Here is a tip that will help you to figure out what is wrong with yourMicrowave Oven....

Microwave Oven Basic Troubleshooting Tips

If there was a power outage, and then your microwave oven never came back on. Then it could be a possible fuse problem. If the circuit breaker had tripped, then after you turned off the cir. brkr. and turned it back on, then everything should've worked fine. Again, I would lean towards a blown fuse in your microwave. Now you're saying there's power to the outlet, and it still won't go on? Then my easy solution would be to plug it into another outlet, and try it again. Your problem could be that plug. After doing everything I just suggested, at any time did you get a digital readout on your time display in the upper right hand corner of the oven. Basically, is there any lights on at all when you're plugged into the wall. If not, then the problem is in the microwave itself! It could be just as simple as a blown fuse, but I would like you to try these other alternatives first. Feel free to contact me again if these don't work. Good Luck, and I hope I've helped you some. Let me know, Jim 

try to unplug and plug back in

Have you checked the fuse in the plug? Also there is an internal fuse that you have to remove the outer casing to get at. Please make sure the power is off and the plug is removed from wall socket before you start and do not power up until the casing is back on. Hope this helps.

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

Danger! You can receive a serious electrical shock from the components inside your microwave oven--even when it's unplugged. Only a qualified appliance repair technician should perform any repair.

It doesn't work at all
It sounds normal, but there's no heat
I can't adjust the power level
The carousel won't turn
I have intermittent cooking problems
The display flickers
There's no heat, but it buzzes loudly
