If you mean a loud buzz that cuts on and off as the oven works, it is probably the outer metal cover vibrating as the magnetron powers up and down. Try holding/ pushing/ poking the metal cover while the oven is working, if the noise abates or goes away, this is the problem.
You may get relief by simply tightening the screws securing the cover, if not, maybe a little careful insertion of a thin strip of cardboard or similar, at the point the vibration occurs, may dampen it. Good luck.

  1. MagnetronIf your microwave is emanating high pitched or growling noises during operation, the magnetron could be going bad. Normally a nearly silent part, the magnetron uses high voltage and induces the frequency required to cook food. Although normally not a safety hazard to operate, this is a sign that the magnetron is failing and will need to be replaced as soon as possible.
  2. Exhaust fan motorIf your microwave is making a very loud humming noise during operation, it could possibly be the exhaust fan motor. If defective the part will need to be replaced to silence the appliance once more.
  3. Stirrer motorAnother leading cause of a noisy microwave is an expired stirrer motor. With use this part becomes worn and makes a loud grinding noise, which is usually a leading indicator that the part needs to be replaced. The stirrer is a metal blade that is slowly turned by the motor. This action disperses the microwave energy in a random pattern, which heats the food evenly. If the stirrer motor is determined to be nearing expiration, it should be replaced to halt the grinding noise.
  4. Turntable motorA very common cause for a noisy microwave is a worn out turntable motor. This is a relatively easy repair and will put an end to the noise once replaced.

    Constant rattling noise during operation


    possibly the "stirrer" motor - this is in the top and turns a metal reflecting ring to disperse the microwaves around the oven more evenly. About $70 on GE site for my oven.
