Do i need an expert to change circuit board in boiler?

[Lemmonie]

I know whats wrong with the boiler and it needs a new circuit board, is there any problem with me doing it myself?

[The real Apache]

have a look, if it has connectors you're ok to do it

I have done the PCB board on my boiler, much like a motherboard on a PC, just take lots of photos of the existing connections. Pretty straight forward.

Some boards have potentiometers or dip-switches to set and adjust.
