Mine hasn't failed for AC. I think it is inside the disconnect box (I
can check). Not much rain in the desert -- 4" per year.

I do plan to use a Square whole house SPD in the breaker panel
(round-to-it).

Installed one in my brand new panel last week.

Not an expert, but I guess lightning killed an electronic board for
my washer or it was a surge spike? TV was protected during the same
storm, no problem.
