Potterton Profile 60e boiler

[T.W.March]

I have Potterton Profile 60e which is over ten years old. Recently it had been taking longer start up, which got to the point where it refused to fire at all, although it was still drawing air and sparking as usual. It was suggested to me that a hair drier might start it (which it did) after removing the lower cover and playing it on the terminal block area, as the problem may be caused by a component that has begun to deterioate with age. Can anyone advise me on exactly what this part is and if it's still obtainable. many thanks T.W. March.

Most likely PCB 407677. Worth buying genuine Potterton unit as opposed to pattern part though.
