Microwave is Not Heating
Microwaves have heating components called diode and magnetron, which emits heat to the food. When burned out, your food won’t heat up and thus they need to be replaced with a new one to get your oven up and running once again.
Microwave Stops in the Middle of Cooking
When your Microwave shuts off in the middle of cooking, it’s probably a problem with the switchboard. A bad wiring connection heats up and causes the fuse to trip, and then cuts off the power.
Additionally, microwaves need a good amount of space for ventilation. Placing them in a cramped space may cause them to overheat and shut down in the middle of cooking until it cools down again.
Microwave Plate is Not Spinning
A damaged motor beneath the plate is the most probable culprit behind your microwave plate not spinning as it should. This can be easily replaced by your electrician. In case, it’s not a problem with the motor, the next thing you need to look into is the switchboard. Caution! Don’t try this yourself. Get a licensed electrician check it for you.
Does it look like your microwave is enjoying some fireworks? Well it’s probably just another indication that your oven has a problem. Peeling off paint from the inside walls is one of the most common cause of this, as the microwaves instead of reflecting from a smooth surface begin to get absorbed and cause sparks. Also worth checking is the rack support for any damage and finally, look for the diode burn out.
No Light Inside
We all like to have a peek from time to time as our food cooks inside the microwave. But you feel blindfolded when the microwave lights are not working. This can be caused due a fused bulb, a faulty socket or a bad wiring. In case, all of the above are in good shape, next you need to check the switchboard to see if it is even sending the power to the bulb or not.
