Our microwave oven turns on but makes a loud vibrating sound and does not seem to heat anything put in it. Does this sound like the tube that just went bad??

In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

I have a "continuous" humming sounding when units are heating. The sound is very loud


The humming sound that occurs may be similar to the annoying buzzing my GE microwave produces at random. It could be mechanical vibration. Doesn't seem to affect cooking.

Danby microwave does not heat food and makes loud constant noise


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.

Loud buzzing noise with Whirpool microwave oven when it comes on. All lights, heating and fan seems to work but not sure why loud buzzing. What is the problem?


The loud buzzing you hear is the sound of the magnatron tube.That is what emits the microwave radiation and buzzing should be normal. The mag tube may be nearing its end at witch time you will hear no buzzing and hence no heating of foods. Replacement can be costly depending on the model so most people just opt for a new one. Hope this helps

Vibrating noise when cooking


In order to try to set your mind at ease I will have to explain the Basics on how a Microwave Oven Functions.
When a Microwave Oven is set to COOK ...START. It cooks at 100%. There is no lowering of the heat as with a Range ( Cook Top) Control. So in order to do the other things such as DEFROST, WARM, or anything other than 100% COOK. A COOK ON- COOK OFF system was utilized. To DEFROST, the Microve COOKS at 100% for 30% of the TIME, then IDLES for 70% of the TIME. COOK ON 30% of the TIME, COOK OFF 70% of the TIME = DEFROST This is why you can hear the CYCLE. More power is required during the ON CYCLE, thus the lower vibration. The Vibration occurs when the High Voltage Transformer is turned ON ( COOK ON).
The VIBRATION seems to have got louder with age. This is somewhat normal as there is a vibration from the High Voltage Transformer present every time the Microwave is used. screws and other metal parts seem to get loose with this vibration. There is no solution, unless you can tighten EVERY screw, nut, and bolt in the unit.
Sorry!

Microwave makes loud buzzing sound when on and no heat


Have you tried putting a cup of water in it and cooking on a low power level? If it buzzes only when it is on the cook cycle, that would narrow it down. More detals might help us help you, including the model number.
