G'day Kiukle,
Is your brother an Electrician?
I think I can see a panel mount fuse in your video so I assume you checked that first up.
If you refer to the attached you have a temperature switch, Heating Element and maybe something mounted under that bracket at the bottom.
The temperature switch should be closed until the fog cylinder reaches a preset temperature.
A few simple checks with a multimeter, by someone who has an Electrical background, should quickly find the fault.
