2 Problem with the magnetron tube

If you hear a growing or high pitched sound coming out from the microwave when it is cooking or heating food then this is a signal that the magnetron tube may have become malfunctioned.  This tube basically does the work of creating the frequency which thereby cooks the food.  When it is in good condition, then device works silently however when the appliance becomes noisy, it may indicate that the tube needs to be repaired or replaced.  The magnetron may be failing or burning out.  To repair or replace, you may need to call an experienced technician.

    It’s good that you mentioned that worn out turntable could be the cause of your strange microwave noises. The microwave in my kitchen has been making strange vibrating sounds and I can’t see any problems with the turntable. I think it’d be a good idea to call a professional to see if there is a way to repair my broken microwave.

    Bought new $600 KitchenAid microwave that had 6 tiny bumps on right side of the interior of the bottom, so called KitchenAid who said contact seller for inspection. Seller sent another Microwave but it had same problem with these bumps. Seller ordered 40 new microwaves of this type from KitchenAid, but the one they sent me again had these bumps, so seller now wants to have KitchenAid technician come out to assess whether a problem or not. I am now happy, as suddenly there might not be a problem???? Your view?
