I'm getting no ignition spark on my Potterton Prima 30F. It has had a new module and pressure switch, and it had a new fan 18 months ago. The fan spins up and the pressure switch is closing, but still no spark.

I'm told that the electrode is getting 115Volts AC a few seconds after the fan spins up. Is this normal, or has a faulty module been fitted?

Probably more out there to be found.
