Hi everyone, I have a J25-32 Mk III boiler. The Fan speed regulato
buzzes like hell. I can get hold of the parts to fix it but I wonde can I replace them myself. I need to replace the regulator and also th main control board as I have been told that this is what caused th regulator to go in the first place. I work in Electronic Security so feel it should be something I can tackle. I wondered if there i anything I need to look out for when replacing the parts. Any help o advice very welcome and appreciate
