Riello oil burner problem

thats true sorry did not read all posts

If the Photocell on a riello is faulty, or the solenoid, or if the motor is not kicking out 50Vac on the White, the burner will purge forever ands a day!
Change the B****y Photocell.

P.S You can test the theory, by unplugging the cell from the control box and refitting the box without the cell you should then get Purge 12secs Flame Light 5secs followed by Lock-out, this will prove that the yes youv'e guessed it, the photocell is unbelievebly, FAULTY

if the electrodes or electrode leads are faulty then the control box will continue to allow the motor to run for hours. it does on the reillos fitted to camray 3s. probably does on most

I'm sure with your greater experience you're probably right. Are you saying that the fault can never be in the control box? It's been working for a day now with the old Photocell and a replacement control box.

It could be either one or both. Changing one may make it work, but how near to failing is it?

New control box arrived this a.m. Photocell is in post

Do the Maths! Photocell £5-65, Control Box £65... Which would you try first, hmmmmmmmmmmmmmmmmmm

A decent
Engineer would have a cell a box a coil and a motor on his van so all this pillocking around would be avoided, how long has this franky simple fault been going on for now? my customers would have exploded by now you are very lucky to have a very patient one!!

Maths done
It is my house If it was winter I would have gone 4 miles to our workshop on Sunday. I knew someone would be coming here on Monday, he brought some old kit we had, being peasants we never throw anything away.
Tried changing coil and PE cell to no effect. Try old rough looking control box it works . Job done before 9a.m.
Why are you paying so much for parts when I get them from Scotland, delivered next day for less . Will fit them when/if needed. After all it's only a boiler, not rocket science

I hope you didn't think i was going to Quote you Trade Price for parts silly boy!

Neither did I think you would have told me how much you would charge to come out on a Sunday to do such a simple job

Hi,
My answer comes late, but ... the question why the Riello coil has three wires remained unanswered. And google directed me here in search of this question.
So maybe still this information can be useful...
The coil gets 29 V DC at ignition, switching to 3 Volts during run. The coil has two tappings; the first to use the full coil potential to CLOSE the valve, then reduced voltage to hold it there.
Btw, my google search was how I got to know this website and I'm very glad I found it!
