Any IC can go bad. I think the KAxxxx are made in Korea where they are still learning how to make stuff.
Name brand parts are very reliable.

this and all the questions has to do with this inverter blowing fets but now i found 2 resistors shorted together where the extra wire from conponents on the under side is supposed to be trimmed off so maybe this will prove to be the culprit.
