You'd be surprised what kinds of things have firmware (although maybe not, if you work in IoT). A normal dumb fridge, a normal dumb dishwasher, most ovens, and definitely microwaves will have firmware. Even if they have no interface to update it. In some cases, the firmware was written using a chip programmer before the chip was soldered in. But there's still firmware. Any appliance with a clock will have it, because otherwise, you have to implement a clock in a CPLD or discrete logic gates or something. A microcontroller is just cheaper.
