Microwave - Door Design

Microwave doors have an outer door, a mesh screen in the window, and a plastic shield or film that covers the screen. This article explains the design and purpose of the components of the microwave door.

Microwave Door Design

The microwave door components are composed of the following items.

• The mesh screen, which is scientifically designed to allow viewing into the microwave, reflects the microwave energy and prevents it from passing through the window or plastic.
• A choke seal which is a protective layer around the door. This assists in containing the microwave energy into the oven cavity.
• A plastic shield or film on the inside of the door that covers the screen. This should not be removed.
• The door also has two safety interlock switches and one monitor switch.

It is normal to have a small amount of play to the door (up or down) approximately 1/8", especially on over-the-range models.
