A microwave is pretty basic, all the "intelligence" is in the magnetron, you don't touch it.
Probable cause, food. There is the power supply for the filaments of the tube, unlikely that the fault is there since it is connected directly to a winding of the transformer. It is therefore necessary to check the HV power supply. We must have> 4 KV. If less, possible causes: the HT diode (also unlikely, in the event of a fault it would frankly burn out), the HT capa, or even the capa protection diode. You have to test them one by one and be equipped for that.
Of course we cannot eliminate more annoying things to locate, such as a partial short-circuit of the secondary winding of the transformer, a protection that is triggered wrongly, the timer that messes up ...
I would start by opening the box, warming something up for it, and checking that there isn't a component that heats up abnormally (or already blackened), which is always a good lead to find a fault.
