how can i fix my worcester heatslave boiler? ?

Good Morning,

I have a Worcester oil fired boiler, Model 'Danesmoor 15/19 (HJ.19000.). Boiler works OK apart from an issue with the compustion fan. The fan does not seem to go off and being that the pump is coupled with it also, I'm afraid it's going to wear out quickly. Therefore I'm only switching the boiler on at the moment when I need it. I believe the Over run relay logic board (408401) may be faulty? But I'm not sure, as I don't have a set of drawings. Any help or advice would be gratefully received.

Kind reagrds
Peter
