Write a thorough training class on commercial Dryer ignition Box for a course for technicians- it must be very thorough for beginner level

We need a thorough course around 3000 words taking from what is ignition box to what they look like- where to find them. What they do. Signs they are bad - how to troubleshoot or test them. How to remove and replace - guided towards a for dummies approach I would like some pictures added
