I bought a GE microwave oven model wes1450dm1bb at the USA, but now I am in a different conutry that uses 220 volts as standard. I just read the user manual and in any place says the voltage of the microwave. Can someone tell me if I can plug it directly to 220 volts electricity or may be convenient to use an adaptor to go from 110 to 220 Thanks

Take it back to the dealer and enquire if this is normal. If it isnt, then exchange it for another and check in the store itself, before you take it home. If it is normal, then you have nothing to worry about :)

On appliances like this only the heating elements use 220 volts. things like the clock, fan, etc use 110 volts. That is why some things work and other do not. Start at the breaker, sometimes a double pole breaker will have 1 side tripped, but will look perfectly fine. switch the breaker all the way to off then re-set. If nothing changes follow the power to the appliance remove the panel and look for some fuses, check to see if any are blown. Also sometimes the microwave will have a separate power source even though its built in to the same appliance. So that's not always a good symptom to follow.

sounds like the hi-limit switch

Please mention the model of your sharp microwave oven. You can log on to the Sharp site to get details of your model:

First thing that comes to mind is to make sure you are getting the correct voltage to the oven, you need 220 / 240 volts, check your breakers, fuses ,etc.
It is possable for the microwave oven to operate even if the power supplied to the oven is only 110 volts, but that low of voltage is not enough to power up the ovens heating elements.
If all seems well there, then maybe the oven element has failed / shorted ?
Good luck !

Usually this is a bad turntable drive motor in the floor of the microwave but the only way to know for sure is to do some electrical testing with a volt/ohm meter and the wiring diagram located within the appliance.

Not sure, maybe broiler and oven element on different circuits?

Electric ovens use 220 and gas ovens use 110.
