I have checked foe air locks and the power supply and they are fine.
the red light on the re-set button is not showing red anymore.
is there a second re-set button on the Riello RDB burners

not much info to work with, but there is only one reset on reillo burners. if you do have power ,than swithing relay could be defective. possible power surge.you could try jumping thermostat wire at relay. if burner does nothing , than good chance switching relay is no good.
