check to see if your intake pipe or vent is clear this could cause a flame jump and make it look like a bad flame sensor let me know if this helps

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.

Yes. On the board mounted inside the furnace box. There will be a series of posts that have numbers printed below each post. The heat motor uses low speed so it should be a sort of fat (larger than most of the other wires) red wire attached to one of the posts. If the wire is on 60, for example, then move it to the next lower post, like 30. unplug the cord on the furnace first. The wire SHOULD be red but may be blue, don't let the color guide you, look for the place where the wires go. If you find the place I'm talking about and the wire is black, then let me know, because its wired to high speed, which is wrong. I will help you.
