These are exactly the kinds of questions that get asked and answered all the time over at Appliantology, so if you are a tech member at that site, post it there. If you aren’t yet a member, what are you waiting for? 😉
The Student Forums are for questions that are specifically related to the coursework. Sometimes the question might come up because of work. For example, trying to apply a particular troubleshooting technique shown in one of our courses to a particular situation you are dealing with in the field.
