What Happens When Your Microwave Sparks?
When a microwave sparks, it means that something inside the appliance is causing an arc of electricity, which can be dangerous. This can happen if there is metal or foil in the microwave, if there is damage to the interior, or if food with a high water content is heated for too long. If you notice sparking in your microwave, it’s important to stop the appliance immediately and inspect it for any damage or foreign objects. Do not use the microwave again until the issue has been resolved or it has been checked by a professional.
