oil boiler blowing rcd on ignition........help please

[billy7771]

hi all
we have a worcester danesmore oil boiler 15 years been brilliant untill christmas eve.........
she will post purge fine then as she goes into the start up sequnce she runs right up to the ignition point( i think ) then the rcd trips.
struggling to find a local guy to come out untill next week just wonderd if there was anything i could look at as i have a load of spares from a friends old boiler i could try replacing.........
hope this makes sense and thanks in advance

Unplug the solenoid and fire the boiler up, if it goes to lock out rather than tripping the rcd then replace the coil.
Look at the transformer to see if it's deformed.

Post back if no joy...
