This page covers microwave waveguide covers waveguide basics and waveguide component manufacturers.
The cover, typically made of mica sheets, is usually employed inside a microwave oven. Its purpose is to prevent food and moisture from falling into the open waveguide cavity.
After a period of use, this cover, which is initially rigid and hard, can become soft, leading to the emergence of holes. This can cause sparking during operation and allow moisture and food particles to enter the cavity.
Consequently, the microwave oven may not function as expected. When these symptoms are observed, it is recommended to replace the microwave waveguide cover. Dealers or manufacturers usually handle this replacement.
