it should also been taken into account that a competent person (in this case a gsr engineer) changing a component that is not related to the combustion of the appliance will likely spot any safety issue's with the appliance when its fixed and working again. A non competent person may not and put somebody at risk by turning the appliance back on.
Wether or not the problem component is combustion related a full understanding of the appliance is important in many cases.
Ask yourself : if you was a gsr engineer would you want to give advise to somebody who has no proven competence? its not easy to say yes.
