When Should You Replace Your Wave Guard Cover?

Replacing a damaged mica plate is essential for microwave safety. You should replace yours if you notice:

  • ⚡ Arcing or Sparks: You see visible sparks inside the microwave during operation.
  • 💥 Burn Marks or Dark Spots: Visible scorching, black spots, or burning on the plate.
  • 💧 Grease Saturation: The card feels soggy, heavily grease-stained, or discoloured.
  • ✂️ Physical Damage: The card is cracked, flaking, broken, or missing pieces.

Safety Tip: Operating a microwave with a missing, burnt, or saturated wave guard can permanently damage the magnetron and create a fire hazard.
