why microware is running, no heating?
Answers:
Actually, the microwaves are generated by a device called a magnetron and waveguides direct the electromagnetic radiation toward a diffuser, which then engulf the cabinet interior. The magnetron sounds like it went out. Problem is, they can get expensive to replace/repair, so the best bet is to buy a new oven, but try to find an appliance repair shop that could take the old one in for parts, instead of chucking it in the landfill. Help the environment too!

Sounds like the tube blew. There is a part in the microwave (yes, it is called a tube) that creates the energy. If it burnt out then the lights are on but nobody's home. the tubes have a warrentied life of 5 years.

That is the signal that you need a new microwave.
Check the fuse. You can buy them from the local hardware store.
