Hello alll,

I have a firebird combi oil burner with the riello burner rdb in. It was working perfect up untill yesterday where it's going straight into instant lockout and won't do anything. Not fuel related because I can see it squiring out.

Any guesses to what it could be ? Thank you
 
Ignition problem?, try cleaning the electrodes or possibly photo electric cell.
 
My 16 year old Firebird does a 12 sec purge, followed by ignition coil + oil solenoid energised, it then allows 5 sec for the photo electric cell to see the flame, so even if photo cell failed then might see a flame for a few secs.? You can hear mine lighting off quite clearly.
 
It’s possible a cell is functioning but not well enough. Using a multimeter in series you can check the micro amps. Don’t know what that reading should be though. An RDB box going straight to lockout suggests the box itself. If a little more information was provided I’d have a better picture of the problem.
