The Waveguide Cover is an OEM part for Viking microwaves. This part protects the microwave's internal components from food splatter and ensuring the efficient distribution of microwaves within the cavity. The waveguide cover is made from a material that allows microwaves to pass through while preventing food particles and moisture from entering the waveguide itself, where they could cause damage or affect the appliance's performance.

Causes of a bad waveguide cover can include accumulation of food particles, moisture leading to the degradation of the material, or physical damage such as cracks or holes.  

Symptoms of a bad Waveguide Cover include:

• Arcing or sparking inside the microwave during use
• Uneven cooking or hot spots in food
• Visible damage or deterioration of the cover
