Does the Aroma rice cooker actually shut off when it's done?

Quick one for the rice cooker regular out there!
See, when the rice is done, the rice cooker do not power off. Instead it simply turns to “Keep Warm” mode. So it essentially mean the rice cooker will stay on and continue to heat the rice, albeit to a more lower temperature. To power it off completely though, you has to manually press the power button.
I suppose this is to ensure that the rice will always be warm until dinner time! Though, I can see how this may being confusing for many rice cooker buyers!
Have any of you thought about how long you typically leave your rice cooker in “Keep Warm” mode before you power them off?
I’ve heard from others who use rice cookers that leaving the rice cookers on for extended periods of time (hours) can dry out the rice or damage the inner pot coating over a time.
However the rice cooker manual just says that it will switch to warm mode and that's it. There is no explanation of how long the rice cooker should be allowed to remains in warm mode.
Does anyone else have thought on this? Is it worth plugging into the rice cooker after the cooking cycle is complete? Or is it best to keep the rice warm for dinner and then unplug after?

mine sits on warm for like 3-4 hours during dinner prep and the rice is fine. Anything past 5 hrs and the bottom layer start getting that crusty dried out ring. Wouldnt leave it overnight on warm tho, thats just asking for funky rice in a morning
 
Yeah they all do this. Basically every rice cooker that is cheap will do it the same way. Essentially, the rice cooker’s warm setting is just a duty cycle for the same heating element but at a lower wattage.

wait does the keep warm feature pulse on and off or is it a lower wattage setting for the rice cooker?

Same heating element but pulsed on and off with a thermostat or control board. The basic Aroma rice cookers use a bimetal switch that clicks back and forth on and off. You can hear it click.
 
the inner pot coating thing is real if youre cheap with how you treat it.
metal utensils + hours on keep warm = peeling teflon within a year. Ask me how i know lol
 
how does anyone trust a $25 appliance to know when the food is done cooking? the mechanism is pretty dumb as rocks, there's a magnet that loses its grip when the pan hits past 100C as the water boils off the pan. That's all there is to it. People act like rice cookers are some kind of magic.

so if its just a magnet that loses its grip when the pan hits 100C, would that mean its possible to under cook the rice at higher altitudes where the water reaches boiling point at a lower temperature?

yeah that can happen. If you're at a higher altitude the water boils at a lower temperature so the rice will cook to a crunchy texture. To avoid this just add a bit more water when cooking the rice. People who live at higher altitudes already know this.
 
fwiw i've been using my aroma cooktop since 2018 and i've never had an issue with the keep warm function. I leave my rice on for the whole evening. All you have to do is fluff the rice once it clicks over. Otherwise, the top dries out and the bottom gets soggy from condensation.
