Potterton Starting Problem

[lordwoody]

My Potterton Suprima 60 is having trouble starting.

Its flashes orange then clicks (not ignition clicks) and goes back to continuous orange this keeps going until it eventually ignites.
the fan does not run when this is happening.

I have had a new PCB 5111603 fitted last year, a new fan and motor fitted this year, the electrode is fine.

Could it be the air pressure switch or does that kick in after the fan starts?

Any ideas anyone

This is a a gas/combustion problem which we don't advise on here.

You have already been dabbling with parts you should not have accessed.

Best to call a gas reg engineer.

It is fairly rare for the new ones to fail.

Only one of the perhaps 10 that I have fitted have subsequently failed.

Have to fit one soon to replace an old one.
