Just to clarify. Often electricians get asked "can you fix this" or "can you have a look at........" and when asked why the asker has asked, the answer is....it uses electricity, you are an electrician.....
It doesn't work like that any more, things are becoming very specialised. If it were the case, who fixes a washing machine? plumber, because it uses water or electrician as it uses electricity. The answer is neither, you get a washing machine repair man (so called washing machine engineer)
I think Andy's idea is easiest
