Yes, disassembling and tinkering with microwave is almost the only easily available thing I would not recommend at all because it seems so ordinary but actual danger is way too high and hidden. Even if you know exactly the dangers, it takes only one distracted move, just being tired or too complacent to end really badly. Like even some medium time disconnected and expectedly safe units can have real nasty shock in them when discharge resistor is faulty, that failure mode does not usually kill but not recommended.
