Another possible cause of sparks or arcs is a damaged or worn-out waveguide cover. The waveguide cover is a thin sheet of material that protects the microwave’s antenna from food splatters and moisture. Over time, this cover can become damaged or develop cracks, allowing microwaves to escape and potentially cause sparks or arcing. Regularly inspecting the waveguide cover for any signs of damage and replacing it if necessary can prevent this issue.
Faulty electrical components within the microwave can also lead to sparks or arcs. This can include issues with the magnetron, capacitor, or high-voltage diode. If these components are malfunctioning, they can cause electrical discharge, resulting in sparks. In such cases, it is recommended to contact a professional technician to diagnose and repair the specific faulty component.
Furthermore, excessive food splatters or debris within the microwave can contribute to sparks or arcing. When these substances accumulate on the interior surfaces, they can absorb microwave energy and heat up, potentially causing sparks. Regularly cleaning the microwave and ensuring it remains free from any food remnants can help prevent this issue.
