I have a Burnham oil boiler with a Beckett burner on it. The burner
does not fire up. It just kind of buzzes or hums a bit for about 30
seconds then shuts off. I am hoping I can get one more week out of
this unit because I am getting the whole unit replaced next week, but
I have a couple of cold days in the mean time.
Any tips on what might be the problem.
Check if your oil is getting to the nozzle. it could be clogged, or
you might have air in the line, in that case you need to unscrew the
bleeder on the burner assembly. Also check the obvious, is oil running
in the line to the burner.
I once had one that wouldn't fire but would if I gave it a good smack
with the side of my fist. I opened it up to find a tiny string of
carbon looped from one electrode to the other. One good smack would
break the loop and it would start. The cause of the problem was the
last guy to service the burner... ME! I had the electrodes adjusted
wrong. Eventually I learned the right way but have forgotten it by now.
The fist smack did the trick. I don't mind doing this for a couple of
days because I have a whole new system coming in on Wednesday. I just
need to make it through a couple of chilly nights until then. If I
get the house up to 70 by bed time, it should stay above 60 unti the
morning when I can smack it another time.
