Microwave making loud, rapid noise (grinding/knocking)

Our microwave is making a loud, rapid noise (grinding/knocking) when operating (except in convection mode).

The noise appears to come from the under turntable area. The turntable stops turning.

Can anyone please give us some ideas?

Thanks

SOURCE: Microwave turntable is loud and clunky sounding.

If the unit is brand new as you say then it is covered under the warranty and the 800# for Bosch is in your paperwork that came with it.

It sounds like the glass platen (turntable) hub is either binding or else the drive mechanism itself either has a bad tooth on the main gear or tooth wheel. Some may still use a chain type drive mechanism as well.

If you call that 800 number - the customer service dept there will advise you as to what needs to happen next. It's possible they will either replace or repair at their expense.

Who installed the unit?

Let me know?

Best regards,

Frank

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

If yours is a GE, you can usually find helpful exploded view diagrams and order parts by entering your full model number here.

If yours is a GE, there should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

SOURCE: microwave turntable won't turn

You may have a tunrtable motor or spindle problem..
This info is from GE website..( link : http://genet.geappliances.com/geasearch/Dispatcher?REQUEST=GETSEARCHRESULT

To minimize the possibility of electric shock, unplug this appliance from the power supply before attempting any maintenance or cleaning.

  • Make sure the turntable is centered and seated properly. On models with a stirrer motor there is a shaft protruding up through the floor of the microwave. Make sure the turntable is securely fastened to this shaft. On models that turn on a ring with wheels attached, make sure the turntable is seated securely on the ring.
  • Check the turntable to make sure it is placed right side up. If the turntable plate is upside down it will drag on the floor of the microwave.
  • Check to make sure that there is no food or debris under the "wheels" of the turntable ring. Food can prevent the wheels from moving forward.
  • Be certain you are pressing a cook function rather than a timer function.
  • If the microwave has a turntable on/off feature make sure the turntable was not inadvertently turned off. Try depressing the turntable on/off pad to re-engage the turntable.

When you close the oven door the latches operate a couple of interlock switches that control power. It may be that one of the door switches is bad or out of adjustment. It's also possible that one of the door latches is broken so it's not hitting the switch. There should be two door latches. Are they both there? This oven could be fixed by adjusting or replacing the interlock parts as needed. Because of concerns about microwave leakage from an improper door seal, you should have this oven serviced by a professional.

  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.

    Microwave made a loud grinding noise while heating a cup of coffee for 1 minute,now everything is shut off. We checked the curcit breakers all ok, and there is power going to it!


    see this causes and fix it. God bless you
    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.
    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.

    Exhaust Fan Motor If the microwave is loud when running the fan motor might be

    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.
