Potterton prima F 50F not firing

[jameshayes]

never had air presure switch faults on these nice boilers.
fan to cycle on and off with no ignition is usually the pcb.
had lots of corroded flues with these boilers but potterton bought out a remedial flue kit which makes it an easy repair.thanky you potterton.

Have found pcb fault to usually be poor solder joins where the main plug clips in
I have before resoldered these and never had a call back
Got a few used ones in my shed i have fixed and checked Always nice to turn up and get it going quickly
