My oil fired boiler with a Reillo RDB burner, and has developed a new fault:
The motor starts and quite often instead of lighting there is a sort of short brr hmmm noise which last for 2-3 secs and is then repeated about
The burner does not lock out and quite often eventually fires up normally.
The boiler is about 9 years old and I replaced the motor and oil pump about a year ago.
Which part do you think is failing?
If it's not locking out despite failing to ignite I'd be immediately suspicious of the sequence control box.
Thank you. Oddly enough it has decided to work properly for the moment.
Just biding its time until the next cold snap/Christmas eve/New Year's eve. ;-)

I fear it is waiting until I go away and the temperature outside drops below zero. I did take the burner off the boiler and found a little unburnt oil on the nozzle support. The nozzle is screwed in tight but maybe there is some dirt causing a small leak. I've ordered a new spanner so that I can hold below the nozzle when I try to unscrew it.
