Simply use Safety. Unplug. Use Continuity Buzzer, Meter ( With Continuity Tone ). Can Use Meter if You Have & Watch, Check By AC Power Cord Fuse. Use a 500 Ohm to 5000 ohm Resistor on two Insulated clip leads with screwdrivers and Find the Hi-Voltage Capacitor ( Large Metal with Leads and a Diode on it. Short the Condenser from one side to another to BLEED any Voltage left Charged in the Condenser. Newer Microwaves have a Bleeder Resistor 10 MegOhms Built in. But Just do this for Backup/Sure Safety. Will Probally Just find a Blown 15-20 amp fuse ( Electrical Surge ). Any one of the 3 Door switches that DONT open-Close Smoothly Will Blow Fuse. ( Intermittent, Burnt, Skipping, Hanging up ). A Shorted Hi-Voltage Capacitor or Diode Will Blow Fuse. Open in Series Protection device may have opened because of Overload or Surge. These are Metal and loop in-Out AC Line and are Mounted ( Heat Sinked to Metal case ).

Microwave has no power


Hello, welcome to Fixya!
The unit not powering on is an indication that it has a power fault.
First, remove the microwave's power cord from the wall, wait for about 30mins, then plug it back in. It may cool by then and might power on. If it doesn't power on, plug it into another outlet, to make sure there electricity entering into the unit.
If plugging into another power outlet doesn't power it on then the unit is most likely having a power problem.
When electric current comes from the power outlet into the microwave, it goes straight into the power supply board which then circulates the current into the unit. So if the microwave doesn't power on, the first thing is to make sure there is power entering into the machine.
So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.
If any machine or electronics device doesn't power on, it means its having a power problem. It might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.
This microwave must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the microwave turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.
To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store within our vicinity.You might also find visible bad component without testing with a meter. This is the only way by which you can detect the problem.
Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.
I wish you the best of luck.
Take care.
