extractor fan just humming

They may have washed it out with a non conducting oil.... Nah doubt it.

if you wash them out with pure water then it will be fine cause its the contaminents in tap/bottled water that fries electronics

could have used cooking oil, I heared of people using standard cooking oil to cool electronics

You have big domestic fans in you part of world mr Marvo!

I have a 300mm fan in the ceiling of the bathroom in my guest flat (wired directly off the light circuit and no separate isolator) , I'd have thought a 12 inch fan is a bit small for most commercial applications like kitchen extract TBH.

I wasn't doubting you at all, its just that a 4" fan is normal for bathrooms here. You usually only see 6" fans when some numpty installer doesn't understand the basics of ventilation and thinks a bigger fan will improve the ventilation when all it really needs is some airflow into the room.

At 9 years old it's probably full of crud that's baked on so it doesn't owe you anything. So swop it out for a brand new sparkly all singing all dancing 12 million megapixal blowjob thingy, other than that try WD40. lol

You can’t be serious.

The moment you start to wash anything the water picks up contaminates.

OP, just change the fan, if it’s a commercial operation they can afford it.

Vegetable oil is used for some transformers, it’s a bit purer than the stuff in your local geasy spoon.
