A flat piece or cover that is attached to the front of a device or machine, often used for protection or to hold components in place.
The technician replaced the faceplate on the device to ensure it was properly sealed.
Faceplate → It is formed from "face" (from Old French *face*, meaning the front or surface) and "plate" (from Old French *plate*, meaning a flat object or sheet). The word "faceplate" refers to a flat surface that forms the front of an object, often covering or protecting its inner components.
Think of the 'front' ('face') of an object being covered by a 'flat sheet' ('plate') — that's what a faceplate is.
