Well thank you "Mr Agile" for pointing out the obvious "you are not a professional (I presume you mean plumber)". If I were I would not be asking questions here now would I? (by the way you have no need to answer, this was more of a rhetorical question, if you don't know what this means I suggest you look it up in a dictionary).
My purpose for posting here was to help people in a similar situation, not to hinder or demean unlike yours presumably?
It is completely obvious that you are an imbecile and have not fully read my post (or at least understood it). As if you had you would not have made the blatant mistakes in your response that you have (i.e. I fitted a repaired PCB NOT a fan as you have seem to have indicated in your reply!).
If you had also read the post correctly you would have noted that I found the wiring diagram after I had initially attempted to diagnose the fault. For your information powering components above their rated current specification (good electronic design prevailing) where a fuse is in place rarely causes them to fail, that is the purpose of the fuse (i.e. to protect the circuit from drawing excess current and damaging more expensive components in the first place). If this wasn't the purpose of a fuse then we need not fit them. We may as well just use a transistor/diode etc as our fuse, after all the component value is somewhat similar.
I would suggest that people like you who are of little or no help on these boards unplug yourself from the Internet and take up something like crochet as a hobby instead. Maybe you would be of more use giving your "professional" advice on a topic such as this at the local W.I.
By the way I also suggest you use a spellchecker when making a post, or learn to type, you might also try not making double posts as this uses precious energy and disk space of people kind enough to provide these message boards.
People like you who have "superior knowledge" make a mockery of these self-help message boards. Also considering the tone and content of your reply I would suggest that in future it may not be a good idea or advertisement for your company.
If I were looking for a “professional plumber” it would be a cold day in hell before I contacted Agile Services.
On a closing note I would just like to let you know that my boiler
is functioning perfectly at a fraction of the price that a "professional plumber" (like yourself no doubt) would have charged, thanks to the friendly advice I have received here and from others.
Do have a nice day.
