SOURCE: Microwave doesn't heat anything

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

My smeg microwave will not heat the food ...... possible causes

If everything else is working but it won't heat the food, the causes are the magnetron "common failure" or the high voltage capacitor and diode can be a factor, the three work together to heat the food. Depending on the nature of repair it can be close to the cost of a new microwave oven.

Does not heat food.

Dont have many smegs where i am, but smeg is a decent unit, so i would think if there is no heat, look for a reset button (over temp. protection). possibly located at the back where the elements are wired.

the door protection circuit needs attention, the door catches operate microswitches, but there is also a third which is a crowbar microswitch. if all three do not operate in the correct sequence then the safety switch or fuse will go.

Smeg microwave SA 31MX not heating is it repairable and at what cost and where at we live in werribee victoria

it is repairable, the problem is the magnetron needs to be replced ( an element that emits the micro waves ) but will need to be checked to make sure its not the capacitor that starts it or the circut that controls it.
repair shops vary so ask them about how much they would charge to replace the magnetron then you will be able to tell who will end up charging you the most and who would be cheeper(aprox $50-$75 plus parts
