OP was totally right here. Many of the replies are from years of experience. OP clearly states he’s new to all this. He may not know what to look for regarding damage through a small cut hole. What if the damage was behind some plastic or styrofoam or what if the point of impact caused damage elsewhere?
To boot, these Home versions of Sterns have lesser builds. Different cabinet materials and construction. They don’t even use metal side armor for the PF glass. Plastic lockbar. BG held on by a flimsy plastic thing with 2 small screws. That impact could’ve done damage elsewhere. OP not knowing WTF was going on chose the correct route - the safe route. Hoping it gets resolved properly.
