Hi,

With no sound coming from it then that will be your magnetron tube.If it was the transformer or the other parts inside it would be putting out a very loud humming or smell like it has a short in it.Its in the hi-voltage and can cause you harm working on it so before you start if you do i would like you to read this :-

Consumer Product Safety Commission
Electrocution Hazard with Do-It-Yourself Repairs of Microwave OvensCPSC Document #5061
The U. S. Consumer Product Safety Commission (CPSC) warns against do-it-yourself repairs of microwave ovens. Each year, on average, four people die from electrocution trying to repair their microwave ovens. Microwave ovens use high voltage which makes it particularly hazardous for consumers to remove the cover and touch electrical parts. The possibility for electrical shock from a microwave oven still exists even after the oven is disconnected from the power source. Should certain internal devices fail, even unplugged ovens can cause serious injury.

The Commission strongly recommends that consumers have professionals repair microwave ovens because electrical appliances can be hazardous if consumers expose live electrical parts.


/!\ WARNING

ELECTROCUTION HAZARD
HIGH VOLTAGE

Removing the cover of your microwave oven and touching an electrical part can kill you.

Have a professional repair your microwave oven.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Most likely you have a magnetron problem. Easy to replace (DYI) but make sure the high voltage capacitor is fully discharged first against the case.
