    Same problem. Extremely noisy fan above the magnatron. It is easy to demonstrate that the fan is the problem. I got a replacement from GE. It was quiet for about 30 days and now the new one is noisier than the old one.

    So worse then selling you junk, they sell you junk replacement parts too.

    Everything inside is marked LG by the way.

After you turn it on, it's a loud noise like it's coming from the fan, but other then that it works wonderfully.

Could you describe the noise?

It may be a noisy fan motor or a failing magnetron or high-voltage transformer.

Microwave occasional loud buzz


make this test and fix it. God bless you


  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.

Magnetron


If the microwave is loud or noisy only when cooking, the magnetron tube might be defective. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances the magnetron is nearly silent. However if it is damaged or nearly burned out it can begin emitting high pitched or growling noises. It's not normally dangerous to use a microwave oven when it makes these noises, but they are an indication that the magnetron is almost dead and will need to be replaced.

Stirrer Motor


If the microwave is loud or noisy the stirrer motor might be worn out. The stirrer is a metal blade which slowly turns around, deflecting the microwave energy in a random pattern inside the microwave oven. As the motor nears the end of its useful life it begins to make grinding noises. The microwave will not heat food evenly without this stirrer, the motor should be replaced.

My microwave makes a loud humming noise when it is turned on.


May as well use the microwave as is until it terminates naturally. All microwave ovens buzz, that nothing unusual, but although you can replace a Magnetron, the cost is unusually high. By the time you take the oven down, open the case and fuss around, perhaps not making things any better; the fact is; a new replacement with a warranty is just over $100. Why bother?

IF the noise is a sound coming from the oven area, its the megatron tube. Typically, replacing the megatron tube is more expensive than replacing wiht a new unit and a new warranty.

hello Frank. Sorry to tell you that the magnetron is going bad and making that terrible noise. Since the inside of a microwave, even unplugged has up to 2000 residual and deadly volts of electricity I recommend either calling a pro or replacing the unit.
