[QUOTE="kme, post: 330736, member: 113"] Right. Fans ( last time I looked) were electric thingies - most boilers use 230VAC units - so testing `em is as easy as it can be. Ditto for the switch -it IS a switch. If the fan isn`t working, it won`t trip the switch, which tells the boiler that the fan has started. Easily proven to work by GENTLY sucking / blowing on the small rubber tube attached to the switch - if the boiler goes into ignition sequence, and the fan isn`t running, then check for volts at the fan. If the fan doesn`t have volts, its either damaged wiring, or a blown fuse ( most likely). Open it, and check it yourself - don`t let it scare you - you don`t have to touch the gas valve side of things....... n.b. What make / model is the boiler? [/QUOTE]
