When the oven is empty none, or almost none of the microwaves are absorbed. A large amount of energy reflects around the oven chamber resulting in large standing waves that can damage the unit. If the microwave works after it has been run while empty, then the unit is safe to use.
What happens if you microwave nothing?
When a microwave runs without anything inside, or if an item contains no water molecules, the microwaves in the machine will be redirected into the magnetron. When the magnetron begins to absorb as many microwaves as it produces, it can be damaged.
How long can you microwave nothing?
Typically you can even run a microwave for 2-3 minutes, sometimes longer while empty (no load) and it will be fine. This is what happens when you run it without a load. At first, everything is fine because the cavity, the door, the tray (or shelf) absorb the excess energy.

It depends on the rock. Some rocks, like those made of silica, are microwave transparent. And so the microwaves will pass through and nothing will happen. Because ores are typically composed of different phases with different microwave properties, some phases heat while others do not.
Why microwave is bad for health?
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat.
Is microwave cancerous?
Microwaves are not known to cause cancer. Microwave ovens use microwave radiation to heat food, but this does not mean that they make food radioactive. Microwaves heat food by causing water molecules to vibrate and, as a result, food is heated.
