yes it should, after demand then the valve should move in the airing cupboard then the pump kicks in then fan. If the fuse hasnt blown by this time then your pretty much sorted with the fan being the problem

Will the pump fire up without the boiler firing up because thats what I think is happening

Hi I've tried firing up th boiler by removing the blue wire on Terminal T6 but nothing has happened. Any ideas?

likely to be the fan, if you can disconnect the wires and attempt to fire boiler up and pump runs without blowing fuse then fan would be next stop
