My dumb refrigerator has a circuit board controlling the compressor based on temperature sensors.
My dumb gas water heater has a digital control unit even though it doesn’t use AC or battery power.
Same thing for gas furnace - control board running fan and gas igniter+valves. This isn’t just relays…
It’d be a substantial effort to design analog drop-in replacement parts - if even possible. Installation probably wouldn’t be pretty.
At least I think my toaster and rice cooker are fully analog.
