riello kerosene burner

[buffy27]

rdb series riello 40 [the small one]
when powered up it is doing nothing... the normal humming noise prior to proper firing is not happening at all. the air intake flap at the side does not lift ..there is a really low mermer out of it ..no life !!!!!! [plenty of oil,getting electricity ,etc etc ..nothing very obvious] any idea s appreciated ..buf.

Could be a number of things. Oil may be getting to the burner but is it reaching the nozzel ? Its oing to be a case of checking each item one at a time.

Possibly the motor and / or capacitor which could be why it makes no noise

check if the electrodes are clean , and is nozzle clean, some time after you get an oil delivery dirt and water stirred up from bottom of tank can get into the pump .

replace control box (satronic/honeywell ?)
check oil filter.
check air damper.
check fan motor - that controls oil pump, so no fan, no oil at nozzle
check oil pump pressure.
replace nozzle.

Please read the OP as stated its doing nothing

story is that the boiler stopped working last year and was left idol..i then had a look ..gave it the basic service..it ran like a clock for a month and then the above mentioned sickness struck it down.
...i know and understand the working principals and firing process !!
the burner is spotless..1st thing i did was clean her up ..swapped atomizer .cleaned photocell...gave electrodes a rub..blast-tube scrubbed..checked control box for any discolouration.. baffles and boiler chamber cleaned.
in the mean time i have replaced it with a spare burner i had at home ....

is the fuel in the line , water, is pump cam turning ok

 

[buffy27]

the replacement one is working fine ..straight swap..fuel/water/circ pump a1.
am i correct in saying .....power to the burner energises the solenoid ..this activates the motor which opens the air damper while the fan draws in air to run the fuel pump..
so problem is, i am not getting the air damper to open or the fan to run to draw on air!!!!
