Question about Microwave Ovens

1 Answer

I have an Ikea MBI 710 S Microwave. For the first year it was quiet, but it is now very noisy. When the microwave function is used there is a loud buzzing. The whirlpool engineer has diagnosed this problem as the magnatomitor causing the thin metal sheet of the case to reverberate. The engineer said he may be able to provide a special material that may stop this from happening without compromising safety or functionality of the unit.

    Tried this. I have since taken it to a specialist repair centre and they want 140 pounds to replace the transformer. They are confident that this is the cause of the problem... its nice to have a second opinion before spending this sort of money...any comments? AH

Try tightening the screws up on the magnetron and transformer as this often causes the problem. If they are tight, loosening them off and re-seating them can also work.

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.

    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.
