its model is NN-ST757W
and no error display only when i set it to timing and press the start button it would go off
Electronics Technician: Pete, Electronic Engineer replied 11 months ago

Ok, so there is likely a problem with the magnetron that generates the microwaves, and it is shutting the system down when it tries to start up.

The magnetron will need to be replaced at a service center.

Electronics Technician: Pete, Electronic Engineer replied 11 months ago

Yes, a faulty magnetron will draw excessive current, causing the fuse to blow.

Electronics Technician: Pete, Electronic Engineer replied 11 months ago

There may be other faults as well, however the service center should check for those when replacing the magnetron.

No, this part is not user serviceable. It requires a qualified inverter technician and specialist tools and training.
