Help no spark

[plumbdoc]

Problems with a worcester camry greenstar. There is no spark across the electrodes.
Have tried 2 diferent control boxes , 2 solenoids and 2 photocells as well as checking the pump and the ht leads . there is 50v across white wire.
the motor and fan runs continuously but no spark comes across the electrodes the solenoid does not open and no oil is pumped out.It never locks out as the sequence never seems to get that far. i suspect a simple solution but cannot see it atm any ideas ?? thanks in advance

Are you an oil engineer? If not, then you are better getting the boiler repaired & probably serviced at same time with an engineer.

As above but question: Have you had water ingress in there recently?

Thats a lot of bits to be chucking at a burner.

Whack a Flux Capacitor on it, link it in to the thing-a-me-bob and then fiddle about with anything that moves on the burner and viola! We will all be reading about another house explosion due to people meddling in things they don't know!!! And the blame would probably be put on the previous engineer (before the fiddler got involved) the poor old chap 🙁 I know it cost £60 to call him out but this custard wanted a chinese not a safe working boiler!!!! OMG!!!! rant over......

I'm reading too many of these things and it winds me up, sorry chaps.

Why try 2 of each part? If the first didn't fix it then why would the 2nd? What are the chances that the new part will have exactly the same fault as the original fault?

Very true. I can't remember many burner new parts with same fault as old one, except oil pumps.
