Microwave Vent Grille (Black) WPW10310713

Literally a five minute job to install. A few screws.
The problem is the part itself. This is like the third one like this we’ve had. The first failed under warranty, the second after a few years. I don’t know if it’s the heat or what, but the attachment area is weak and breaks after a few years. I epoxied it back together which helped for a while. Just a poor design.
