hello, my boiler shuts its self down including pilot , i already found dry joints on control board,which are done now. the pilot goes out because boilers overheating and when central heating switch is off rads still heat up? gas valve seems to be on all the time when it shouldnt be , it does seem to be an elect fault would i be correct ? ive checked all stats ,pressure sw, vac sw ,flow sw,are ok what am i missing ?
