Main washroom Fan is running (not turning off)

Hi,
My main washroom fan is suddenly running non stop, it has switches in the washroom and one in the First floor (near thermostat), none seem to be working.
Any idea why ?

I couldn't find any thread discussing this specific issue here, but I did find some threads in the internet , most of them for US...

Thank you so much.

I found vidoes that disconnect the fuse after removing the Fan net, I don't want to do that as it would stop the fan forever.

Thanks again.

So 2 switches (3-way presumably) control the fan? Could be the switches are broken so power is connected all the time.

Remove the fan cover. You should see the plug for the fan. Pull out the plug.

Very possible, I even feel the switch is loose, but why the second switch is not responding. That is why I am surprised and like to see if anyone experienced this.

Could be some strange wiring configuration, and maybe power is supplied direct to the fan (some auto switch feature) and the switches are on a separate switch circuit.

Thank you did it. Fan is stopped now (one less issue), now I need to replace the switch which I will do it. when I opened the cover I see the switch displays the word "Common Switch", I will take it to home depot for replacement.

I doubt anything strange about it (it worked all these years), as said, I felt the switch bit loose, possibly it got worn out. let me investigate replacing it.

It's a 3way switch.. if its loose something broke in the toggle so it's not disconnecting.

Some fans have a switch that automatically turns on the fan when humidity is higher than a certain amount... Check if your fan has those. If not, then you've solved it. If yes, before you change your switches, make sure it's not the humidity in your house auto starting your fan...
