switch heating or water on for heat, indicator light 2 & 3 come on, pump runs and fan starts, but main burner does not light up now. yesterday the main did light up but it took an age, now it will not light up at all, anyone got any ideas, is it the PCB control board?? any help welcome.
By the way I had a new gas valve, fan and air pressure switch fitted last year.
