AC Powered Leaf Blower, blown electronic component.

A/C powered leaf blower will not power up.
Unit is a 2 speed blower (Off / Low / High ).
Unit is a WeedEater, model: Baracuda 2595 Super Blower, 120v, 12A, Type 1. ⏎

Upon disassembly, discovered an electronic component (a diode, or a capacitor ? ), that is across the AC input on the main power switch has failed, and is in pieces!

I need to understand what size of diode (if it is a diode?) goes across the power switch.

Given a 120v input voltage, and rated for 12A...?
I need to know:
i) how to engineer the size of diode for replacement?
ii) why is this unit a "type 1", versus a type 2, or 3, that I've seen on parts lists ( for parts that are not available!! )
