Samurai Appliance Repair Man posted a blog entry in Samurai Appliance Repair Man's BlogIn the last webinar, we put on our Master Samurai Tech hats and did a cleanup service call on a gas oven after a parts changing monkey (PCM) had already been out and failed to diagnose and repair the problem. We looked at what the PCM did on the service call as well as he did not do but should have done. We did a quick review of how hot surface ignition (HSI) systems work and how variations in supply voltage can affect the operation of these systems. Then we got inside the head of a Master Samurai Tech and analyzed the problem like a professional technician would: by applying a detailed, technical understanding of the system being troubleshot and understanding how to use specifications to interpret electrical measurements and anticipate ignition system response.
