A couple of years ago in the wok hei thread there were a couple of comments about mother board failures. I never circled back on the subject to address another post, but most people are unlikely to cruise an old post about wok cooking to learn this. Mother boards do not like high heat. In this regard, they do not seem to wear out from multiple high heat uses like cleaning cycles. They just get too hot and fail. I have experienced this on first cleaning cycle (and second). Home made Neapolitan pizza is not worth the cost of a new mother board. Appliance repair people have confirmed that my experiences were not unusual.
