UL really trusts thermal fuses, they're reliable and can not be reset which calls attention to the user that something is very seriously wrong. If the oven was getting hot enough to trip the thermals, then something was seriously wrong and replacing the thermals would not be the cure.
I'm sure that replacing the firmware was the real cure, and that's scary. What if self-clean code was causing a runaway condition? There might be consumers that jumper out the blown thermal fuses rather than paying $260 for the proper repair and then they have a runaway oven with no way to shut it down.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
