I found out why my burner wouldn't stay running at the BBB, it has a burnt out component in the control box, and a replacement box is best part of £100, so I'm looking on fleabay/gumtree etc for another burner, either running and cheapish, or a dirt cheap non runner for the control box.

That's a shame... Is the burnt component replaceable or is the damage too extensive?

Jules asked the same question Tony, it probably could be replaced, but I'm crap at solder work on circuit boards, I'll get a picture taken of the burnt out component/circuit board and see what folks think.

Chug,

Upload the photo, and we can see, but also -

What are you wanting the unit for? If its going to be attended use, then a lot of the control board could be done away with anyhow.

But its probably repairable - they are way more basic than modern units.

there is a picture here, its not very clear but its the oblong box shape component on the left hand side, you can just see the melted top of it, I will try and get a better photo later when Mahli is back from work with her better camera.

It looks like there may be some print on the inner face of it?

If there is (or if there are any markings anywhere on it) try and get a snap of them.

Also, does the control unit itself have a brand / part number? I have one of those burners, and so does jules, but they all have different variations.

Split the topic so it has its own thread.

Agreed it would help to have make and model of the burner and PCB if possible. Looks like it got quite oily, like it would enjoy a good rinse with IPA.

It's not immediately clear what that component is - relay, big capacitor? May have to wait for Mahli's photo.

Its an Electro Oil inter 11 burner the control box is Danfoss BH011 057H2011 but its obselete and replaced by

Danfoss BH972.10 which can also be replaced by a later control box but that also needs a new wiring base
Later box = 057H8102 and wiring base = 057H7224

There is also a Satronic version TF830.3 fitted to some burners

Ill have a look to see whats fitted to mine in a few days. I cant get to it at the moment, as there's 2 drums of bio just in front of it, but im set to pump that elsewhere shortly.

That is just a big capacitor, data sheet for it here

http://www.farnell.com/datasheets/1943741.pdf

really easy to change too.

In fact, by the looks of it, everything on that board is old fashioned and easy to change, no nasty fiddly surface mount stuff
The relay would be a pain to get but as your burner was firing up and running for 10 seconds we can assume that is fine.

I will have a look at the control box on my burner tomorrow to confirm but I suspect it is an easy job. If you want to send it in the post to me I will have a go for you

Chug · « **Reply #11 on:** July 16, 2015, 10:23:15 PM »

aha, that sounds like good news Jules,

whilst you are having a look at yours....
can you look in the very centre of the board at the little barrel component with just one leg that goes between the big black plastic box and the black box orange solenoid thing, as it just fell apart when I was cleaning the board, so it needs that replacing now too!

Wish I was still working at the pressure washer place I used to fall over these.

That is a mains filter capacitor its only there to stop interference from
the boiler the panel will work OK with out it fitted.

its almost identical to this

OK, I took the controller apart on my boiler and took some high resolution pics as below...

The numbers on the outer casing

The rear of the PCB

Closeup of the mains filter capacitor, you will notice that there are some components under it, rectifier diodes and resistors.

the main relay contacts

Mains filter cap from above

The remaining components - a few more caps, some diodes, two transistors and lots of resistors

and finally the whole device from above

It is all real basic stuff electronics wise, all the components should be available and easy to replace.
The transistors do have writing on the can but I was unable to read it with them in situ, you would have to replace one to read what they are.
