When was last service/nozzle etc, I seem to remember sterlings needing to ba accurately set up with regards to electrodes etc. What appliance is it on?

 

[Smac]

Burner is fitted on Turco boiler last serviced 1yr ago what do you advice me on regarding electrodes.

Need some more details.
What made you change control box?
When it fires does it run to lockout, how long does it run for, when it locks out can it be immediately reset.
As above what condition is nozzle? Good oil flow at correct pressure? Fuel filter clean? No water in tank?

It could be a number of things here.Have you checked the photocell?Combustion settings?

 

[Dotty]

As the above also you say it's been a year since last serviced, was it done properly then? are the baffles clean and clear of soot?

 

[Smac]

Oil nozzle has been replaced oil filter has been cleaned checked pump pressure and control box Is siemens loa24 sometimes burner will fire for about 5 to 10 sec and them go to lockout what is best way to check oil tank for wAter

Sounds like photocell, but it could be the solenoid.

 

[Dotty]

sounds like a dirty / dodgy photocell.
