Netaheat profile 60e - Pilot light won't light
I have a Netaheat profile 60e
Symptoms: No main burn No pilot light Fan is running no 'sparking sound' to be heard The 'cutout' (?) button on the bottom is not out (in the past, the boiler has occasionally cut out, and this button pops out. Pushing and holding it in relights the pilot, and then the main burn) Any ideas?? Neal |

Neal first thing you should look at is the air pressure switch as that is next in sequence, check for split pipes or blocked conections, hope that helps pete |

Netaheat profile 60e - Pilot light won't light
there was a problem with the early models that the spark gap opened
up due to the groung post (bent piece of metal ) moving away from the spark electrode, there should be about 3.5 mm gap try that, pete |

But then - nothing Ah - there are two clicks one from the APS and the other from a relay on the pcb You've reached the stage where it is either necessary to measure something or be bold and operate the APS manually. I don't think that the latter option is a good idea if you don't understand what you're doing. To perform the former also requires you to be competent to make electrical measurements -- geoff |

gasman pete writes there was a problem with the early models that the spark gap opened up due to the groung post (bent piece of metal ) moving away from the spark electrode, there should be about 3.5 mm gap try that, pete Nah - I don't think so you'd still hear the spark discharging somewhere, even if not at the electrode. There is a spark gap on the back of the pcb just for that purpose -- geoff |

Since there is no sparking the chances are that the spark lead is shorted No - you'd still hear the spark gap on the primary discharging, it's just that it's drowned out by the secondary spark during normal operation BTW, did an Indian lady phone you today ?

But then no sparks I also think I can smell a whiff of gas in the flue. I think I have reached the limit of my knowledge, so I have a guy coming this afternoon (name found in littlegreenbook.co.uk- wish me luck) I have told him I strongly the suspect the PCB, so he has agreed to try and bring a re[placement with him... |
