Cause 1

Line Fuse

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.)

Cause 2

Main Control Board

The main control board might be defective. However, this is rarely the case. Control boards are often misdiagnosed—check all of the more commonly defective parts. If you have determined that all of the other components are working properly,replace the main control board. (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 main control board.)

Cause 3

Thermal Fuse

The thermal fuse cuts off power to the microwave if the microwave overheats. To determine if the thermal fuse has blown, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. The thermal fuse cannot be reset—if the fuse is blown, it must be replaced. (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 thermal fuse.)

I have a similar issue with my GE Profile Microwave (Model #PVM9215SKSS). There is no power at all. I have checked two ceramic fuses and one Thermal fuse. Those are good. Does it mean that my main control board is faulty? How to make sure if the Main Control Board is faulty?

All the answers here are wrong especially when the microwave is new I don’t think these people answering are understanding the question but I do because I had the same problem!!

It's not the actual microwave itself that is the problem here people it's the outlet we’re plugging it into. You can Google it addressing the outlet not the microwave because my GFCI (the reset button on your kitchen outlet) kept popping out when I would plug it in realizing it’s not the actual microwave mine went on when I finally found the right outlet. However if you live in an apartment and it is two bedroom and up you have an outlet that can handle it, so go find it!! ... HOWEVER, if you have a one bedroom or smaller you will not have an outlet for that microwave and you must have a "Licensed Electrician" come over and switch out the outlet from a 15 amp to 20 amp it will take 5 minutes but don't have anyone else or yourself being unlicensed try doing it to save a few dollars because whoever it is they will die from being fried from the inside out aka ELECTROCUTED!!! It's inevitable THE PERSON MUST BE A "LICENSED ELECTRICIAN" PERIOD !
