#1 YaXun/Aoyue 968 Hot air Soldering station blows heat element

Hello.

I've got an YaXun 968 (it´s the same as Aoyue 968) hot air soldering station burning the heat element.

Inicially I thought that the problem would be the resistence but I have bought a new one and it burned right after turning the machine on.

I searched for the schematics everywhere but no luck, so I'm trying to identify the ICs but all are scratched. I'm attaching a photo, maybe someone has a station of the same model and could share what are U3, U4, U5, U6, U7 and U8.

Thanks in advance.
