Hiya all,

I've got a Potterton 30F gas boiler in the kitchen which (today of all
days!) has gone on the blink. What's happening is that it is trying to start
but not lighting. I can hear the fan engage then the microswitch on the
Pressure Switch clicks (which I assume is in response to the fan) but maybe
it isn't it?! The boiler stays like this for 5 ish seconds then powers down
the fan and it does this repeatedly.

It's a tad cold today and I'd appreciate it if someone has some advice on
what to look at/replace without having to spend £'s on a call out.

Thanks in advance, Adam

A potterton WHAT 30F?
A bit like saying you have a ford 1600

Prima 30F

A little bit more info:
Blowing/sucking on the tubes from the fan does cause the microswitch to
activate. The gas value isn't supplied any power from the control module.
Anyone care to guess at what I should check next?

TIA

I heard a whisper about Potterton sending out boilers with faulty
circuit boards. My mate at work has had a similar problem, he contacted
Corgi(of all people), apparently there is a big court case about this
fiasco, as potterton knew they were faulty when they sent them out. My
mate
got it repaired even out of warranty.
Try corgi, ask if they have heard anything.
If you have no joy, come back to me, and I'll ask him if I can give his
e-mail address, so he can tell you the whole story.

Have you any URL's or other references regarding this matter, PLEASE ?

You can guess who I'll be writing to about the failure of my boilers
PCB......

I read what you say, but do you mean that the microswitch is not
actually changing over from normally closed to normally open, or that it
doesn't cause the pcb to go further through the sequence?

If the microswitch isn't actually changing over when you (gently) suck
or blow, then either the diaphragm in the APS is ruptured or the
contacts have welded themselves together

If the microswitch is physically changing state, then have the contacts
gone high resistance?

If the APS is actually working correctly, then it's the pcb at fault

part no. 407677

The gas value isn't supplied any power from the control module.
Anyone care to guess at what I should check next?

The gas valve won't receive any power from the pcb until the APS
normally open contacts power the pilot valve/spark circuit

p.s. Please don't top post

Do you know which boiler these faulty boards are on ?

Hiya Geoff,

The microswitch does change from open to closed (or the other way depending
on which pipe you blow into!). I can only therefore summise that it's the
controller unit that's not working properly. However, it is also fed by some
sensors which I guess could have failed?

Cheers, Adam

Problem now solved. It was a capacitor inside the control unit. Quick visit
by an electronics friend, quick examination of the PCB, re-solder a dry
joint, swap out the capacitor and the boiler is now working well again.
Certainly beats the £90+ for a replacement!

Dry joints seem to be something Potterton specialise in it seems... :~(

They're not technically dry joints, they're cracked joints due to crap
flow soldering

sorry about the delay in coming back to the group, have had permission from
mate to offload e-mail address to those interested in the potterton fiasco,
and the problems with the pcb boards in them.
if you mail to he will explain , what the problems
are, who he talked to and who sorted the problems out etc, he will tell you
how corgi and trading standards got involved
