Hi to all,
I used this site a few yrs ago and recieved good advice on re-soldering PCB.
I have a potterton Suprima 60 that appears to run up correctly but will not spark.
Once system is on flashing red light showing, press reset button, fan runs, solid green light comes on, green light then flashes @ ignition but no spark @ electrode, can smell gas. Cycle repeats three times then cuts out.
I fitted re-con PCB, system worked fine for a few weeks then started to degrade, boiler locking out, would start if reset, then spark became weeker untill spark was lost.
Have just changed, HT lead, electrode, overheat stat and Temp thermister. Earth checks out ok Gas is being released @ time of ignition, still no spark.
Am I now back to problems with PCB, (possible faulty component that generates pulse for spark)???
Any help would be very much appreciated.
