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. Hugh
Air pressure switch ?
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
look at my site
It's not the relay sticking, it's either a capacitor or the zener diode
