I've been given a nice big Vent-Axia extractor fan to put in the back wall of my garage extension. Just stuck a plug on it and it's blowing
the wrong way, so the electrical gubbins would be on the outside of the wall and exposed to the elements. The rear of the motor has 4 terminals with
only 3 in use (L,N,E). L is currently connected to A0 and A1 is spare. Is it as simple as swapping the live over to A1 to get it spinning the other
way? Or am I about to blow the thing apart in spectacular fashion??
think yove got a window fan. can you fit it on the outside wall instead?
turn the fan round the other way ?

Can you get the fan blades off the motor and mount it on the other way round

Disconnect the live and see if there's continuity through the spare terminal. If there is, connect your live to it via a piece of 2amp fuse wire. See what occurs!

It is more than likely a shaded pole type motor and therefore designed to only run one way.
Sorry

Maybe, but why the extra terminal then?
I've checked my vent axia cataloge and they no longer use that terminal notation so I really don't see why you can't try connecting the
live to the spare terminal and see what happens.
You might get lucky!
If you have room you could mount it to a bit of ply with a hole in the centre, turn it around then box the sides in.
If the blades are designed as a pusher it will not be efficient if you just reverse the motor. It will move air but not like an extractor fan. The spare terminal looks like another neutral shielded from the live and will be a dead short if you put the live in it. I would put the neutral in it first and see what effect it has.

Yeah,
Its been an hour, are you still alive?!?
If its a shaded pole motor (solid rotor and surrounded by coil wound stator then you can reverse the rotation by flipping 180 degrees the outer stator.If you look closeley you will see a shading ring to ensure correct rotation.

It works!!
TBH, I went to rewire it and noticed instructions inside the cover where they were terminated. Saying to swing N between A1 and A2 for intake or
extract, as we suspected anyway. Feel a bit daft but hey it's working now and thanks for all your help / advice
