Merry Christmas! Advice needed on blown ACB - just replace or investigate further?

Hi all - I'm looking for advice from someone who knows more about ACBs than I do!

Woke up this Christmas morning to no hot water or central heating - boiler refused to fire. Further investigation showed that the problem was with the ACB board on the Boilermate 2000 - LED light 1 for 'boiler on' was off and when I looked closely at the small black rectangular component next to it (sorry don't know its name!) one of the silver connections looked decidedly frazzled and there was a black burn mark on the board. I obviously need to find out whether the board can be repaired or will have to be replaced, but my question to all you helpful Boilermate 2000 experts is do I first need to find out what caused the connection to blow? The board was a reconditioned one from Ebay so maybe that's the problem; or could it be because the system has been on full-pelt for over a week due to the bad weather? I don't want to spend £250 on a new board just for it to go again.

Any advice would be appreciated.

Re-con board / e bay sounds iffy.
Did you program the board to your appliance?
Would say get a new board and fit it properly
Should be ok.

Hi Mike, thanks for your reply. The Ebay company sold it as a GT155 board for a Boilermate 2000 and I installed it as per the instructions in the manual that came with the appliance. It has worked fine for just over 3 months (the guarantee was for 3 months of course!) Not sure about any programming that was needed?!

When fitting a new board.
You normally have to put a jumper on number 5 to check it is for your unit.
It might be A01 or A03 etc.
Its in the book.
After accepting the right code, you switch off remove the jumper.
And away you go.
Some books give the wrong code though.
Can be confusing.

Hi Mike - thanks again. Yes, did the business with jumper no.5. I'm still thinking it could be the board though - I knew I was taking a chance with a reconditioned one but the new one is so expensive.

Hi all - just thought I'd give an update to (hopefully) finish this topic off. Bought a new (genuine) ACB and installed it this morning - so far everything is working fine. Fingers crossed there is no repeat of the problem and we can enjoy hot water and heating for the first time in a week.
