Question about Microwave Ovens

1 Answer

Noisy Microwave I have had my LG microwave for about 3 months, and its now very noisy whenever its heating something. Nothing is on top or sides which would cause vibration, however when you press in the middle of the outer metal casing of the microwave it stops. should you take your hand off it starts again. Would it be worth getting it fixed? Any ideas if it would be under warranty?

On the right side?

Usually there is a rubber pad on the high voltage transformer which prevents vibration due to the magnetic field of the transformer.

If that falls off, it can make the side vibrate.

Either way, since it's less than one year old, it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

  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.
Exhaust Fan Motor If the microwave is loud when running the fan motor might be
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.
Turntable Motor If the microwave is loud or noisy the turntable motor might be worn out. This is a common problem and relatively easy to replace.

Noisy magnatron


First of all, if you press against the right side of the outer cover of the oven, does that lessen the noise? If so, it may be that a rubber cushion on the side of the HV transformer has fallen off.

If it had that hum but was not heating, I would first check the HV rectifier diode.

But since it's cooking, I would say your magnetron is on the way out.

Unless the warranty is about to expire, I'd continue to use it and watch and wait.

A component of the high voltage section has shorted, possibly the diode. If it was the capacitor, it would normally blow th fuse.
If it is the high voltage transformer and you continue running it,
it should devolpe smoke in about one minute. Either way, a part
will have to be replaced to correct the situation.

Noisy turntable


I has this problem with a Sears unit. The repairman simply removed the glass tray, cleaned all the wheels and the 3 toothed driver wheel in the middle and it became quiet. He explained that if any buildup keeps the plate from properly seating on the gear, it gets very noisy.
