The Smeg microwave is used to cook food in a hurry. If you are having problems with your Smeg microwave, you might be tempted to hire a repair person or to just toss it in the trash. You don't have to hire anybody or buy a new unit. You can troubleshoot the issue yourself with little knowledge of the subject. Most of the time, a microwave only needs a little bit of attention before it is back up to its full potential.
Go to the back of the unit and make sure that it is plugged into a working electrical socket.
Use your fingers to go over the power cord. If you find any breaks or frays, replace the cord immediately through a hardware store.
Open the microwave and check the turntable. The turntable is the glass plate the food spins on. Make sure that the plate is resting properly on the turntable.
Check over the door assembly. If the door does not shut properly, a sensor will disable the microwave from turning on.
Pull the roller out of the microwave. This is the plastic piece that the glass plate rests on. Soak the roller in warm water and then clean it with a rag to get any food particles off it. If the roller isn't working properly, food will not cook correctly.
Clean the interior walls of the microwave if your food is not being heated properly. If the walls are dirty, the heat will not disperse evenly.
Wipe down the touch pad if the buttons do not work or are intermittent in function.
