My Potterton Profile 80 Boiler, will not start, the system is live,
the fan Kicks in and out, along burst at first, then a 5 second gap
follwed a a 2 second burst on the fan. But throughout it simply wont
fire up. I have tried using the reset button on the bottom og the
boiler but still nothing.

Does anybody have any ideas??

Not to familiar with the boiler, but does it have pilot flame or an electronic
ignition system ? It could be that the main gas valve inside the boiler isn't working
properly or the pilot flame / electronic ignition detector is shot.

possibly sensor or over-heat thermostat problem? not too expensive if it is.
Check the boilers manual for fault-finding, and 'phone Potterton technical
dept. with the symptoms - they should give you a list of possibilities.

Is this a repeating cycle? If so its the control box.

I'm not totally sure but I think the underlying cause is that the relay is
stuck. Mechanical encouragement may unstick for a while.
The problem is that the fan start the APS responds but the relay does not
switch over to keep the fan running so the APS fails after a second or
two. Then the fan is powered again and so on....

Replacements are readily avilable from cetltd.com .

IMHO you should chuck it and install a replacement by a different
manufacturer to save you long term grief

It's either the air pressure switch, or, more likely the pcb

It's not the relay sticking, it's either a capacitor or the zener diode
