Microwave Ovens - Recent Questions, Troubleshooting & Support

I searched using https://www.google.com but did not locate an instruction manual for that model Sharp microwave oven.

Recipe at the link below suggests adding extra sugar before baking.

You will need to take it in for repair. The case is secured by security screws due to the dangers of microwaves and the very high voltage electricity stored in the main capacitor.

Depending on how long you have had it, you may be able to contact Ostler under warranty.

Or if old just replace it

It could be an internal fuse, or there could be a magnetron problem. Irrespective, you can't work on them yourself as the case is fixed with security screws as they are so dangerous inside. The only thing you can check for is a fuse at the back, but unlikely to be that as it works, albeit with no heat.

Most microwave ovens contain a heavy transformer that produces a lethally high voltage that is half-wave rectified by a diode, smoothed by a capacitor and drives a magnetron. The transformer also provides a low voltage for the magnetron cathode heater.

There are also lightweight microwaves that use an inverter instead of a transformer...

If everything else is ok and power is being supplied to the transformer then one of the above components has failed but testing them is beyond the scope of the handyman, though with care some ohm meter checks can be carried out in a unit that is disconnected from the supply and if the capacitor isn't fitted with a discharge resistor great care must be taken to ensure it is fully discharged before handling it.

There is a problem with the magnetron or power supply to the magnetron.
Take it to an authorised Panasonic Domestic Appliance repairer for service.
