Almost certainly, the component called the "magnetron" has died. This is the valve (tube in the US) which actually generates the microwaves. The loud humming is the transformer that supplies the magnetron being overloaded and/or the magnetron itself. If the rest of the appliance is OK and not too old, the magnetron can be replaced. If you aren't familiar with these appliances, you *must* get this done by someone who understands the dangers of messing with them - if you get it wrong, they can bite! In some countries, only qualified engineers can buy the spare parts. In the UK, the part costs around £40 - £80, depending on the model. If the appliance is more than around three years old, it may be a false economy to repair it as other parts may fail soon after the repair.

Replace the vent fan


Russ
Try heating a cup of water for two minutes. I bet it doesn't. A sign of a magnetron being defective is a loud hum and no heating. Unit is then not economical to repair.

KEY PAD SEEMS FINE BUT WHEN YOU HIT START UNIT MAKES LOUDER THAN NORMAL HUMMING NOISE AND UNIT DOESN'T HEAT ANYMORE


The magnetron has failed or the high voltage transformer is the problem, either way! it is very expensive to replace, cheaper to buy new.

Magnatron suddenly making more noise. Much louder


Often over the years the Transformer laminations can loosen, from the on/off rising and collapsing magnetic fields, and then they sorta hum louder. I suspect this is what is going on. Shouldn't be too much of a worry.. keep an eye on it tho.
