The first knackered Potterton PCB of the season.
My Potterton Suprima 30 was refusing to fire up for more than a few
seconds yesterday, so I followed Potterton's Fault Finding flow chart. This got me as far as "are the two yellow wires to the thermister (sic) shorted?", which was a no. The next but one step was "are the two white wires to the temp control shorted?", which was a yes and therefore "replace Electronic Control", by which I assume they mean the PCB. However, as part of checking, I inspected the wiring to the thermistor and carefully pulled it in and out. On reassembling everything, it now seems to be working as normal. Is it possible that it is the thermistor not conducting heat properly rather than the PCB? -- Hugo Nebula 'What you have to ask yourself is, "if no-one on the internet wants a piece of this, just how far from the pack have you strayed?"' |

Sorry - I can't help with your question but an an aside, how do I get hold
of a Fault Finding flowchart for my boiler: a Potterton Netaheat 60e ? The only relevant document I can find is the User's Guide at http://www.potterton.co.uk/literatur...e_30-80_ug.pdf Thanks Paul "Hugo Nebula" abuse@localhost wrote in message ...

Is it possible that it is the thermistor not conducting heat properly rather than the PCB? Unlikely I would have thought Even if it doesn't have heat sink compound around it, being physically held in place, there's bound to be reasonable conduction to it from the immediate area. What's the resistance at room temp and up at operating temperature ? The information contained in this post may not be published in, or used by http://www.diyprojects.info -- geoff |

When my P S 80 adopteded the 'fire, fail to fault' mode of operating this time last year I remade all the solder joints on the PCB and it has worked fine ever since. Correction; it has worked as well as one can expect from that model ;-) Richard -- Real email address is RJS at BIGFOOT dot COM The information contained in this post may not be published in, or used by http://www.diyprojects.info |
