Icon 30s 12V fan not moving but shutter opened

[Ivan810216]

I fitted an icon 30s 12V fan to the bathroom. The old one is a model 15 with 220V connection. I didn’t realized the old one is 220V, I thought it must be a 12V fan as my house is a new built.

Anyway, I connected the fan directly with 220V and circuit tripped and the lighting switch also damaged.

I replaced the switch and circuit not tripping anymore. When switching on, the shutter opened but not the fan.

Would it be the case the motor had been blowed as the shutter can opened meaning that the power supply is okay.

Anyone can help me with this ?

Sorry, I'm slightly confused.
You wired a 12V fan to the 230V mains supply, causing a trip and damage to the switch.
Then you changed the switch, but didn't remove the 12V fan before reconnecting the 230V supply?

After replace the switch, I of course removed everything and connected again with the transformer and everything and the shutter works fine

But the fan still doesn't work?
The wax motor that opens the shutters may have been slightly more tolerant to the over-voltage than the fan motor and it's associated electronics.
It suggests that the wiring is probably ok.
If you are unsure, post a pic.

Sounds like the 12v fan didn’t like 230v being connected to it

I connected once and then connect them with the transformer provided

Once is enough - why do you think the circuit breaker did its job

Besides, a use a screwdriver tester to touch the Grey terminal which should be neutral but the tester lights up instead.

Those screwdrivers are for detecting mains voltages, not 12v..
Also, they pick up all sorts of spurious voltages. Use a proper test meter, or give up and get someone who knows what they are doing.
