There will be a small tube that goes from the induction blower housing to the switch itself. Try to blow and **** through this tube with it attached to the switch. If you hear a click on the inside of the switch, it is good, if not, then it needs to be replaced. Another thing to try, take a small wire or paperclip and poke through the hole that the hose came off of on the housing, sometimes this gets clogged and will cause the same problem. Other than that, it will be a blocked flue or the inductive blower itself not performing properly. Hope this helps and good luck!

SOURCE: I have a coleman furnace in my mobile home & green light is flashing 3 times. I guess its a centrifugal switch is this expensive and is it something i can do myself?

I would not try to do this, in the uk you need to be properly certified to work on such items. If you make a mistake you could blow up.
