NEVER blow into the APS!

Its a precision device and you will damage it! Just blow TOWARDS the +ve connection.

Measure the resistance of the C to the NC and then to the NO whilst blowing towards it. Should be less than 1 ohm.

Then you need to find out if the APS is really being operated by the fan!

As a very last resort check the O/H stat has continuity. Its on the right hand side of the main heat exchanger but rarely fails.

If the APS is making when the fan starts then I am afraid it sounds as if its the ignition PCB failed. This will cost about £75 or so.
