hi there, my first post on here, just wondering if anyone can help.I have a fairly old oil fired camray 2 boiler with a riello 40/3bm burner.For the last 6 months i knew from the horrible noises that the burner motor was on the way out but just wanted to put off the expense of dealing with it until it was dead,at the same time as making horrible noises (which would sometimes go away for a few weeks before returning again) the lockout was kicking in every few hours requiring me to press the reset on the control box.Eventually even pressing that didnt fire it up again but i found that by opening the hydrolic door on the fan housing and physically pushing the fan round a bit with a pen that it would fire up on the next push on the re set button.This continued until recently when it did finally die,so i ordered a new motor online and paid an engineer(will have a go at most things but not when oil joints are involved) to fit it.He then showed me that the oil pump was also dead so i got one from a plumbcentre parts store and he fitted that.Boiler fired up and off went the engineer ,then 1.5 hrs later,yes thats right..the lockout came on again and after calling him he said it had to be the solenoid on its way out,being an easy job i got the part and fitted it, and still the damn thing goes to lockout at regular intervals.Is the next option to replace the capacitor,or is that nothing to do with the problem? Next in my list after capacitor would be to see if i can get a new /secondhand photocell for the control box and then if that fails a whole new control box.The odd thing is that yesterday after locking out it wouldnt re start until i did the little "push the fan around a bit"trick, maybe that was just a coincidence and it was going to start anyway but it puzzles me as its a new motor and oil pump and both run quitly and smoothly and are not catching on anything.Any help would be very much appreciated. Thanks
