Scott - Failure analysis and root cause analysis can sometimes be tricky. You can do this yourself, but might miss something. If your company has no one on staff experienced in these tasks, it may be best to hire an outside consultant. If you insist on doing this yourself, it is possible, but can take quite a bit of time. Take small steps as you disassemble the product with greater care than you would otherwise use. Take photos and detailed notes at every step. Try to locate the sources of heat that caused ignition (there may be more than one or a cascading effect). Smoke, discolored metal, bubbled paint, charred boards, etc. Try internet searches on failure analysis and root cause analysis. Regards, Peter L.
