There are two possible sources; the fan, which may have a loose sleeve bearing (fan must be replaced), or a transformer with loose laminations. The latter is a rare occurrance since most transformers are 'potted' or treated with epoxy resin.  
After pulling the plug, the housing will be fairly easy to remove with a half-dozen or so screws around the edge of the back panel.
If the fan is then accessible, you could block the blades with any insultating material and briefly turn the unit on. Keep fingers clear of ANY part inside; danger of electrocution. If the vibration is missing, then the fan is at fault.

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.

Jvm1790sk01 GE Microwave Broken - Manufactured Aug 2005. Working fine until tonight. Loud vibrating humming sound coming from Right Side and Burning Odor... No heating on high power. Just burning odor. ...


Sounds like you Magnetron has failed. The only way to repair this is to replace the part. Some microwaves have an extended warranty on this part. Check your manual and Call GE for service if it does. If the warranty has expired you might as well buy a new microwave unless you are very attached to this one. Hope this helps

Is it time to replace the microwave if it makes a loud vibrating sound followed by a pop which is followed by the sound of broken glass?


Yes it is time to replace it, the magnetron has failed and there are two more parts of concern, the high voltage capacitor and diode are also a factor. The high voltage capacitor and diode work with the magnetron to produce the high voltage that heats the food. The vibrating sound is further evidence the magnetron is culprit.

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!
