What to do if your microwave is smoking?
Then, is it normal for a microwave to smoke?
Cooking your food too long in the microwave can cause smoke inside the machine. At times, it can even cause a fire. If you notice sparks or smoke coming from the vent, it indicates that you are dealing with some serious electric problem inside the machine.
Just so, what do you do when your microwave starts smoking?
When splatters do happen and you neglect to clean them immediately, the food residue left behind may end up overheating which can cause smoke to generate in the appliance. To prevent this issue from transpiring, you must clean up all spills promptly by simply wiping down the microwaves interior with warm soapy water.
The metal isn't going to hurt the food in any way, the food should be fine. As long as the microwave seems to function properly, it should be ok, as well. Just don't make leaving metal in the microwave a habit. Technically it could short out or catch fire or otherwise start acting up.
